Beta Features

Using Supervisor as a Process Manager

Warning

Do not use it in production environments yet! It has not been tested thoroughly yet.

Supervisor is process manager written in Python. The main advantage is that it take care about processes, so if bot process exit with failure (exit code different than 0), supervisor try to run it again. Another advantage is that it not require writing PID files.

This was tested on Ubuntu 18.04.

Install supervisor. supervisor_twiddler is extension for supervisor, that makes possible to create process dynamically. (Ubuntu supervisor package is currently based on Python 2, so supervisor_twiddler must be installed with Python 2 pip.)

Change IntelMQ process manager in the global configuration:

process_manager: supervisor
-

After this it is possible to manage bots like before with intelmqctl command.

Using AMQP Message Broker

Starting with IntelMQ 1.2 the AMQP protocol is supported as message queue. To use it, install a broker, for example RabbitMQ. The configuration and the differences are outlined here. Keep in mind that it is slower, but has better monitoring capabilities and is more stable. The AMQP support is considered beta, so small problems might occur. So far, only RabbitMQ as broker has been tested.

You can change the broker for single bots (set the parameters in the runtime configuration per bot) or for the whole botnet (using the global configuration).

You need to set the parameter source_pipeline_broker/destination_pipeline_broker to amqp. There are more parameters available:

source_pipeline_amqp_virtual_host

() (default: '/')

intelmqctl_rabbitmq_monitoring_url

() string, see below (default: "http://{host}:15672")

For getting the queue sizes, intelmqctl needs to connect to the monitoring interface of RabbitMQ. If the monitoring interface is not available under http://{host}:15672 you can manually set using the parameter intelmqctl_rabbitmq_monitoring_url. In a RabbitMQ's default configuration you might not provide a user account, as by default the administrator (guest:guest) allows full access from localhost. If you create a separate user account, make sure to add the tag "monitoring" to it, otherwise IntelMQ can't fetch the queue sizes.

Setting the statistics (and cache) parameters is necessary when the local redis is running under a non-default host/port. If this is the case, you can set them explicitly:

statistics_database

() 3

statistics_host

() "127.0.0.1"

statistics_password

() null

statistics_port

() 6379

Multithreading

First of all: Do not use it in production environments yet! There are a few bugs, see below

Since IntelMQ 2.0 it is possible to provide the following runtime parameter:

instances_threads

Set it to a non-zero integer, then this number of worker threads will be spawn. This is useful if bots often wait for system resources or if network-based lookups are a bottleneck.

However, there are currently a few cavecats:

  • This is not possible for all bots, there are some exceptions (collectors and some outputs), see the FAQ for some reasons.
  • Only use it with the AMQP pipeline, as with Redis, messages may get duplicated because there's only one internal queue
  • In the logs, you can see the main thread initializing first, then all of the threads which log with the name [bot-id].[thread-id].

Common Problems

IntelMQ

Permission denied when using Redis Unix socket

If you get an error like this:

intelmq.lib.exceptions.PipelineError: pipeline failed - ConnectionError('Error 13 connecting to unix socket: /var/run/redis/redis.sock. Permission denied.',)

Make sure the intelmq user as sufficient permissions for the socket.

In /etc/redis/redis.conf (or wherever your configuration is), check the permissions and set it for example to group-writeable:

unixsocketperm 770

And add the user intelmq to the redis-group:

usermod -aG redis intelmq

My bot(s) died on startup with no errors logged

Rather than starting your bot(s) with intelmqctl start, try intelmqctl run [bot]. This will provide valuable debug output you might not otherwise see, pointing to issues like system configuration errors.

Orphaned Queues

This section has been moved to the Management Guide.

Multithreading is not available for this bot

Multithreading is not available for some bots and AMQP broker is necessary. Possible reasons why a certain bot or a setup does not support Multithreading include:

  • Multithreading is only available when using the AMQP broker.
  • For most collectors, Multithreading is disabled. Otherwise this would lead to duplicated data, as the data retrieval is not atomic.
  • Some bots use libraries which are not thread safe. Look a the bot's documentation for more information.
  • Some bots' operations are not thread safe. Look a the bot's documentation for more information.

If you think this mapping is wrong, please report a bug.

IntelMQ API

IntelMQCtlError

If the command is not configured correctly, you will see exceptions on startup like this:

intelmq_manager.runctl.IntelMQCtlError: <ERROR_MESSAGE>
-

This means the intelmqctl command could not be executed as a subprocess. The <ERROR_MESSAGE> should indicate why.

Access Denied / Authentication Required "Please provide valid Token verification credentials"

If you see the IntelMQ Manager interface and menu, but the API calls to the back-end querying configuration and status of IntelMQ fail with "Access Denied" or "Authentication Required: Please provide valid Token verification credentials" errors, you are maybe not logged in while the API requires authentication.

By default, the API requires authentication. Create user accounts and login with them or - if you have other protection means in place - deactivate the authentication requirement by removing or renaming the session_store parameter in the configuration.

Internal Server Error

There can be various reasons for internal server errors. You need to look at the error log of your web server, for example /var/log/apache2/error.log or /var/log/httpd/error_log for Apache 2. It could be that the sudo-setup is not functional, the configuration file or session database file can not be read or written or other errors in regards to the execution of the API program.

Can I just install it from the deb/rpm packages while installing IntelMQ from a different source?

Yes, you can install the API and the Manager from the deb/rpm repositories, and install your IntelMQ from a somewhere else, e.g. a local repository. However, knowledge about Python and system administration experience is recommended if you do so.

The packages install IntelMQ to /usr/lib/python3*/site-packages/intelmq/. Installing with pip results in /usr/local/lib/python3*/site-packages/intelmq/ (and some other accompaning resources) which overrides the installation in /usr/lib/. You probably need to adapt the configuration parameter intelmq_ctl_cmd to the /usr/local/bin/intelmqctl executable and some other tweaks.

sqlite3.OperationalError: attempt to write a readonly database

SQLite does not only need write access to the database itself, but also the folder the database file is located in. Please check that the webserver has write permissions to the folder the session file is located in.

Configuring IntelMQ API

Depending on your setup you might have to install sudo to make it possible for the intelmq-api to run the intelmq command as the user-account usually used to run intelmq (which is also often called intelmq).

intelmq-api is configured using a configuration file in json format. intelmq-api tries to load the configuration file from /etc/intelmq/api-config.json and ${PREFIX}/etc/intelmq/api-config.json, but you can override the path setting the environment variable INTELMQ_API_CONFIG. (When using Apache, you can do this by modifying the Apache configuration file shipped with intelmq-api, the file contains an example)

When running the API using hug, you can set the environment variable like this:

INTELMQ_API_CONFIG=/etc/intelmq/api-config.json hug -m intelmq_api.serve
@@ -21,6 +21,6 @@
 }

On Debian based systems, the default path for the session_store is /var/lib/dbconfig-common/sqlite3/intelmq-api/intelmqapi, because the Debian package uses the Debian packaging tools to manage the database file.

The following configuration options are available:

  • intelmq_ctl_cmd: Your intelmqctl command. If this is not set in a configuration file the default is used, which is ["sudo", "-u", "intelmq", "/usr/local/bin/intelmqctl"] The option "intelmq_ctl_cmd" is a list of strings so that we can avoid shell-injection vulnerabilities because no shell is involved when running the command. This means that if the command you want to use needs parameters, they have to be separate strings.
  • allowed_path: intelmq-api can grant read-only access to specific files - this setting defines the path those files can reside in.
  • session_store: this is an optional path to a sqlite database, which is used for session storage and authentication. If it is not set (which is the default), no authentication is used!
  • session_duration: the maximal duration of a session, its 86400 seconds by default
  • allow_origins: a list of origins the responses of the API can be shared with. Allows every origin by default.

Permissions

intelmq-api tries to write a couple of configuration files in the ${PREFIX}/etc/intelmq directory - this is only possible if you set the permissions accordingly, given that intelmq-api runs under a different user. The user the API run as also needs write access to the folder the session_store is located in, otherwise there will be an error accessing the session data. If you\'re using the default Apache 2 setup, you might want to set the group of the files to www-data and give it write permissions (chmod -R g+w <directoryname>). In addition to that, the intelmq-manager tries to store the bot positions via the API into the file ${PREFIX}/etc/intelmq/manager/positions.conf. You should therefore create the folder ${PREFIX}/etc/intelmq/manager and the file positions.conf in it.

Adding a user

If you enable the session_store you will have to create user accounts to be able to access the API functionality. You can do this using intelmq-api-adduser:

intelmq-api-adduser --user <username> --password <password>

A note on SELinux

On systems with SELinux enabled, the API will fail to call intelmqctl. Therefore, SELinux needs to be disabled:

setenforce 0

We welcome contributions to provide SELinux policies.

Directories

LSB

If you installed the packages, standard Linux paths (LSB paths) are used:

  • /etc/intelmq/ (configurations)
  • /var/log/intelmq/ (logs)
  • /var/lib/intelmq/ (local states)
  • /var/run/intelmq/ (PID files)

Otherwise, the configuration directory is /opt/intelmq/etc/. Using the environment variable INTELMQ_ROOT_DIR allows setting any arbitrary root directory.

You can switch this by setting the environment variables INTELMQ_PATHS_NO_OPT and INTELMQ_PATHS_OPT, respectively.

  • When installing the Python packages, you can set INTELMQ_PATHS_NO_OPT to something non-empty to use LSB-paths.
  • When installing the deb/rpm packages, you can set INTELMQ_PATHS_OPT to something non-empty to use /opt/intelmq/ paths, or a path set with INTELMQ_ROOT_DIR.

The environment variable ROOT_DIR is meant to set an alternative root directory instead of /. This is primarily meant for package build environments an analogous to setuptool's --root parameter. Thus it is only used in LSB-mode.

Using Elasticsearch as a database for IntelMQ

If you wish to run IntelMQ with Elasticsearch or full ELK stack (Elasticsearch, Logstash, Kibana) it is entirely possible. This guide assumes the reader is familiar with basic configuration of ELK and does not aim to cover using ELK in general. It is based on the version 6.8.0 (ELK is a fast moving train therefore things might change). Assuming you have IntelMQ (and Redis) installation in place, lets dive in.

Configuration without Logstash

This case involves two steps:

  1. Configure IntelMQ to output data directly into Elasticsearch.

  2. Configure Elasticsearch for ingesting the inserted data.

Bug

This section of the documentation is currently incomplete and will be updated later.

Configuration with Logstash

This case involves three steps:

  1. Configuring IntelMQ to output data to Redis.

  2. Configure Logstash to collect data from Redis and insert them into Elasticsearch.

  3. Configure Elasticsearch for ingesting the inserted data.

Each step is described in detail in the following sections.

Configuring IntelMQ

In order to pass IntelMQ events to Logstash we will utilize already installed Redis. Add a new Redis Output Bot to your pipeline. As the minimum fill in the following parameters: bot-id, redis_server_ip (can be hostname) , redis_server_port, redis_password (if required, else set to empty!), redis_queue (name for the queue). It is recommended to use a different redis_db parameter than used by the IntelMQ (specified as source_pipeline_db , destination_pipeline_db and statistics_database).

  • hosts - Elasticsearch host (or more) with the correct port (9200 by default)
  • index - name of the index where to insert data

Tip

Authors experience, hardware equipment and the amount of events collected led to having a separate index for each month. This might not necessarily suit your needs, but it is a suggested option.

Warning

By default the ELK stack uses insecure HTTP. It is possible to setup Security for secure connections and basic user management. This is possible with the Basic (free) licence since versions 6.8.0 and 7.1.0.

Configuring Elasticsearch

Configuring Elasticsearch is entirely up to you and should be consulted with the official documentation. What you will most likely need is something called index template mappings. IntelMQ provides a tool for generating such mappings. See ElasticMapper Tool.

Danger

Default installation of Elasticsearch database allows anyone with cURL and connection capability to have administrative access to the database. Make sure you secure your toys!

Using PostgreSQL as a database for IntelMQ

The EventDB is a database (usually PostgreSQL) that gets filled with with data from IntelMQ using the SQL Output Bot.

intelmq_psql_initdb

IntelMQ comes with the intelmq_psql_initdb command line tool designed to help with creating the EventDB. It creates in the first line:

  • A CREATE TABLE events statement with all valid IntelMQ fields as columns and correct types
  • Several indexes as examples for a good read & search performance

Having an events table as outlined in the SQL file, IntelMQ's SQL Output Bot can write all received events into this database table.

In addition, the script supports some additional features supporting use cases described later in this document:

  • --partition-key - for generating schema aligned with TimescaleDB or partitioned tables,
  • --separate-raws - for generating views and triggers needed to eventdb_raws_table (works also together with adjustments for partitioning).

For a full list of supported parameters, call the script help using -h parameter.

All elements of the generated SQL file can be adapted and extended before running the SQL file against a database, especially the indexes. Please review the generated script before applying.

Be aware that if you create tables using another DB user that is used later by the output bot, you may need to adjust ownership or privileges in the database. If you have problems with database permissions, refer to PostgreSQL documentation <https://www.postgresql.org/docs/current/ddl-priv.html>.

EventDB Utilities

Some scripts related to the EventDB are located in the contrib/eventdb folder in the IntelMQ git repository.

Apply Malware Name Mapping

The apply_mapping_eventdb.py script applies the malware name mapping to the EventDB. Source and destination columns can be given, also a local file. If no local file is present, the mapping can be downloaded on demand. It queries the database for all distinct malware names with the taxonomy "malicious-code" and sets another column to the malware family name.

Apply Domain Suffix

The apply_domain_suffix.py script writes the public domain suffix to the source.domain_suffix / destination.domain_suffix columns, extracted from source.fqdn / destination.fqdn.

Usage

The Python scripts can connect to a PostgreSQL server with an eventdb database and an events table. The command line arguments interface for both scripts are the same. See --help for more information:

How to setup

Thanks to TimescaleDB its very easy to setup.

  1. Choose your preferred Timescale DB environment & follow the installation instructions. 2. Now lets create a hypertable, which is the timescale DB time-series structure. SELECT create_hypertable('', 'time.source');. 3. Now our hypertable is setup & timescaleDB takes care of the rest. You can perform queries as usual, for further information please check Timescale DB Documentation.

How to upgrade from my existing database?

To update your existing database to use this awesome time-series feature, just follow the How to setup instruction. You can perform the hypertable command even on already existing databases. BUT there are some limitations from timescaleDB.

Separating raw values in PostgreSQL using view and trigger

In order to reduce the row size in the events table, the raw column's data can be separated from the other columns. While the raw-data is about 30-50% of the data row's size, it is not used in most database queries, as it serves only a backup functionality. Other possibilities to reduce or getting rid of this field are described in the FAQ, section faq-remove-raw-data.

The steps described here are best performed before the events table is filled with data, but can as well be done with existing data.

The approach requires four steps:

  1. An existing events table, see the first section of this document.
  2. Deleting or renaming the raw column of the events table.
  3. Creating a table raws which holds only the raw field of the events and linking both tables using the event_id.
  4. Creating the view v_events which joins the tables events and raws.
  5. Creating the function process_v_events_insert and INSERT trigger tr_events.

The last steps brings us several advantages:

  • All INSERT statements can contain all data, including the raw field.
  • No code changes are needed in the IntelMQ output bot or your own scripts. A migration is seamless.
  • PostgreSQL itself ensures that the data of both tables is consistent and linked correctly.

The complete SQL script can be generated using the intelmq_psql_initdb. It does not cover step 2 to avoid accidental data loss - you need to do this step manually.

Other docs

You have two basic choices to run PostgreSQL:

  1. on the same machine as intelmq, then you could use Unix sockets if available on your platform
  2. on a different machine. In which case you would need to use a TCP connection and make sure you give the right connection parameters to each psql or client call.

Make sure to consult your PostgreSQL documentation about how to allow network connections and authentication in case 2.

PostgreSQL Version

Any supported version of PostgreSQL should work (v>=9.2 as of Oct 2016) [1].

If you use PostgreSQL server v >= 9.4, it gives you the possibility to use the time-zone formatting string "OF" for date-times and the GiST index for the CIDR type. This may be useful depending on how you plan to use the events that this bot writes into the database.

How to install

Use intelmq_psql_initdb to create initial SQL statements from harmonization.conf. The script will create the required table layout and save it as /tmp/initdb.sql

You need a PostgreSQL database-user to own the result database. The recommendation is to use the name intelmq . There may already be such a user for the PostgreSQL database-cluster to be used by other bots. (For example from setting up the expert/certbund_contact bot.)

Therefore if still necessary: create the database-user as postgresql superuser, which usually is done via the system user postgres:

createuser --no-superuser --no-createrole --no-createdb --encrypted --pwprompt intelmq

Create the new database:

createdb --encoding='utf-8' --owner=intelmq intelmq-events

(The encoding parameter should ensure the right encoding on platform where this is not the default.)

Now initialize it as database-user intelmq (in this example a network connection to localhost is used, so you would get to test if the user intelmq can authenticate):

psql -h localhost intelmq-events intelmq </tmp/initdb.sql
-

PostgreSQL and null characters

While null characters (0, not SQL "NULL") in TEXT and JSON/JSONB fields are valid, data containing null characters can cause troubles in some combinations of clients, servers and each settings. To prevent unhandled errors and data which can't be inserted into the database, all null characters are escaped (u0000) before insertion.

Frequently asked questions

How can I improve the speed?

In most cases the bottlenecks are look-up experts. In these cases you can easily use the integrated load balancing features.

Multithreading

When using the AMQP broker, you can make use of Multi-threading. See the multithreading section.

"Classic" load-balancing (Multiprocessing)

Before Multithreading was available in IntelMQ, and in case you use Redis as broker, the only way to do load balancing involves more work. Create multiple instances of the same bot and connect them all to the same source and destination bots. Then set the parameter load_balance to true for the bot which sends the messages to the duplicated bot. Then, the bot sends messages to only one of the destination queues and not to all of them.

True Multiprocessing is not available in IntelMQ. See also this discussion on a possible enhanced load balancing <186>.

Other options

For any bottleneck based on (online) lookups, optimize the lookup itself and if possible use local databases.

It is also possible to use multiple servers to spread the workload. To get the messages from one system to the other you can either directly connect to the other's pipeline or use a fast exchange mechanism such as the TCP Collector/Output (make sure to secure the network by other means).

Removing raw data for higher performance and less space usage

If you do not need the raw data, you can safely remove it. For events (after parsers), it keeps the original data, eg. a line of a CSV file. In reports it keeps the actual data to be parsed, so don't delete the raw field in Reports - between collectors and parsers.

The raw data consumes about 50% - 30% of the messages' size. The size of course depends on how many additional data you add to it and how much data the report includes. Dropping it, will improve the speed as less data needs to be transferred and processed at each step.

In a bot

You can do this for example by using the Field Reducer Expert. The configuration could be:

  • type: blacklist
  • keys: raw

Other solutions are the Modify bot and the Sieve bot. The last one is a good choice if you already use it and you only need to add the command:

remove raw

In the database

In case you store data in the database and you want to keep its size small, you can (periodically) delete the raw data there.

To remove the raw data for a events table of a PostgreSQL database, you can use something like:

UPDATE events SET raw = NULL WHERE "time.source" < '2018-07-01';

If the database is big, make sure only update small parts of the database by using an appropriate WHERE clause. If you do not see any negative performance impact, you can increase the size of the chunks, otherwise the events in the output bot may queue up. The id column can also be used instead of the source's time.

Another way of reducing the raw-data from the database is described in the EventDB documentation: eventdb_raws_table.

How to Uninstall

If you installed intelmq with native packages: Use the package management tool to remove the package intelmq. These tools do not remove configuration by default.

If you installed manually via pip (note that this also deletes all configuration and possibly data):

pip3 uninstall intelmq
 rm -r /opt/intelmq

Hardware Requirements

Do you ask yourself how much RAM do you need to give your new IntelMQ virtual machine?

The honest answer is simple and pointless: It depends ;)

IntelMQ and the messaging queue (broker)

IntelMQ uses a messaging queue to move the messages between the bots. All bot instances can only process one message at a time, therefore all other messages need to wait in the queue. As not all bots are equally fast, the messages will naturally "queue up" before the slower ones. Further, parsers produce many events with just one message (the report) as input.

The following estimations assume Redis as messaging broker which is the default for IntelMQ. When RabbitMQ is used, the required resources will differ, and RabbitMQ can handle system overload and therefore a shortage of memory.

As Redis stores all data in memory, the data which is processed at any point in time must fit there, including overheads. Please note that IntelMQ does neither store nor cache any input data. These estimates therefore only relate to the processing step, not the storage.

For a minimal system, these requirements suffice:

  • 4 GB of RAM
  • 2 CPUs
  • 10 GB disk size

Depending on your data input, you will need the twentiethfold of the input data size as memory for processing.

When using Redis persistence, you will additionally need twice as much memory for Redis.

Disk space

Disk space is only relevant if you save your data to a file, which is not recommended for production setups, and only useful for testing and evaluation.

Do not forget to rotate your logs or use syslog, especially if you use the logging level "DEBUG". logrotate is in use by default for all installation with deb/rpm packages. When other means of installation are used (pip, manual), configure log rotation manually. See logging configuration.

Background on memory

For experimentation, we used multiple Shadowserver Poodle reports for demonstration purpose, totaling in 120 MB of data. All numbers are estimates and are rounded. In memory, the report data requires 160 MB. After parsing, the memory usage increases to 850 MB in total, as every data line is stored as JSON, with additional information plus the original data encoded in Base 64. The further processing steps depend on the configuration, but you can estimate that caches (for lookups and deduplication) and other added information cause an additional size increase of about 2x. Once a dataset finished processing in IntelMQ, it is no longer stored in memory. Therefore, the memory is only needed to catch high load.

The above numbers result in a factor of 14 for input data size vs. memory required by Redis. Assuming some overhead and memory for the bots' processes, a factor of 20 seems sensible.

To reduce the amount of required memory and disk size, you can optionally remove the raw data field, see this section in the FAQ.

Additional components

If some of the optional components are in use, they can add additional hardware requirements.

Those components do not add relevant requirements:

  • IntelMQ API: It is just an API for intelmqctl.
  • IntelMQ Manager: Only contains static files served by the webserver.
  • IntelMQ Webinput CSV: Just a webinterface to insert data. Requires the amount of processed data to fit in memory, see above.
  • Stats Portal: The aggregation step and Graphana require some resources, but no exact numbers are known.
  • Malware Name Mapping
  • Docker: The docker layer adds only minimal hardware requirements.

Database

When storing data in databases (such as MongoDB, PostgreSQL, ElasticSearch), it is recommended to do this on separate machines for operational reasons. Using a different machine results in a separation of stream processing to data storage and allows for a specialized system optimization for both use-cases.

IntelMQ cb mailgen

While the Fody backend and frontend do not have significant requirements, the RIPE import tool of the certbund-contact requires about 8 GB of memory as of March 2021.

In a nutshell, MISP stores manually curated indicators (called attributes) grouped in events. An event can have an arbitrary number of attributes. MISP correlates these indicators with each other and can synchronize the data between multiple MISP instances.

On the other side, IntelMQ in it's essence (not considering the EventDB <eventdb>) has no state or database, but is stream-oriented. IntelMQ acts as a toolbox which can be configured as needed to automate processes of mass data with little or no human interaction At the end of the processing the data may land in some database or be sent to other systems.

IntelMQ - n6 Integration

n6 is an Open Source Tool with very similar aims as IntelMQ: processing and distributing IoC data. The use-cases, architecture and features differ and both tools have non-overlapping strengths. n6 is maintained and developed by CERT.pl.

Information about n6 can be found here:

n6 schema

n6 data flow

Data format

The internal data representation differs between IntelMQ and n6, so any data exchange between the systems requires a format conversion. For example, in n6 one message can contain multiple IP addresses, but IntelMQ is intentionally restricted to one IP address per message. Therefore, one n6 event results in one or more IntelMQ events. Because of this, and some other naming differences and ambiguities, the format conversion is not bidirectional.

Data exchange interface

n6 offers a STOMP interface via the RabbitMQ broker, which can be used for both sending and receiving data. IntelMQ offers both a STOMP collector bot for receiving data from n6, as well as a STOMP output bot for sending data to n6 instances.

  • Stomp Collector Bot
  • N6 Parser Bot
  • Stomp Output Bot

Data conversion

IntelMQ can parse n6 data using the n6 parser and n6 can parse IntelMQ data using the Intelmq n6 parser.

Intro

This guide provides instructions on how to install, configure and manage IntelMQ and it's components.

IntelMQ uses a message broker such as Redis. This is required for IntelMQ to run.

IntelMQ doesn't handle long term storage of processed Events beyond writing to a file. However it provides connectors (output bots) for writing events to various database systems and log collectors. It is recommended to configure such system to preserve processed events.

Base Requirements

The following instructions assume the following requirements. Python versions >= 3.7 are supported.

Supported and recommended operating systems are:

  • Debian
  • openSUSE Tumbleweed/Leap
  • Ubuntu
  • For the Docker-installation: Docker Engine: 18.x and higher

Other distributions which are (most probably) supported include AlmaLinux, CentOS, Fedora, FreeBSD 12, RHEL and RockyLinux.

A short guide on hardware requirements can be found on the page Hardware Requirements.

CHANGELOG

3.3.1 (unreleased)

Configuration

Core

  • intelmq.lib.utils.drop_privileges: When IntelMQ is called as root and dropping the privileges to user intelmq, also set the non-primary groups associated with the intelmq user. Makes the behaviour of running intelmqctl as root closer to the behaviour of sudo -u intelmq ... (PR#2507 by Mikk Margus Möll).

Development

Data Format

Bots

Collectors

  • intelmq.bots.collectors.shadowserver.collector_reports_api.py:
  • Added support for the types parameter to be either a string or a list.
  • Refactored to utilize the type field returned by the API to match the requested types instead of a sub-string match on the filename.
  • Fixed timezone issue for collecting reports.
  • intelmq.bots.collectors.shodan.collector_stream (PR#2492 by Mikk Margus Möll):
  • Add alert parameter to Shodan stream collector to allow fetching streams by configured alert ID
  • intelmq.bots.collectors.mail._lib: Remove deprecated parameter attach_unzip from default parameters (PR#2511 by Sebastian Wagner).

Parsers

  • intelmq.bots.parsers.shadowserver._config:
  • Fetch schema before first run (PR#2482 by elsif2, fixes #2480).
  • intelmq.bots.parsers.dataplane.parser: Use | as field delimiter, fix parsing of AS names including | (PR#2488 by DigitalTrustCenter).

Experts

  • intelmq.bots.experts.sieve.expert:
  • For :contains, =~ and !~, convert the value to string before matching avoiding an exception. If the value is a dict, convert the value to JSON (PR#2500 by Sebastian Wagner).
  • intelmq.bots.experts.filter.expert:
  • Treat value false for parameter filter_regex as false (PR#2499 by Sebastian Wagner).

Outputs

  • intelmq.bots.outputs.misp.output_feed: Handle failures if saved current event wasn't saved or is incorrect (PR by Kamil Mankowski).
  • intelmq.bots.outputs.smtp_batch.output: Documentation on multiple recipients added (PR#2501 by Edvard Rejthar).

Documentation

  • Bots: Clarify some section of Mail collectors and the Generic CSV Parser (PR#2510 by Sebastian Wagner).

3.3.0 (2024-03-01)

Configuration

  • Add new optional configuration parameters for intelmq.bots.collectors.stomp.collector and intelmq.bots.outputs.stomp.output (PR#2408 by Jan Kaliszewski):
  • auth_by_ssl_client_certificate (Boolean, default: true; if false then ssl_client_certificate and ssl_client_certificate_key will be ignored);
  • username (STOMP authentication login, default: "guest"; to be used only if auth_by_ssl_client_certificate is false);
  • password (STOMP authentication passcode, default: "guest"; to be used only if auth_by_ssl_client_certificate is false).
  • Add the possibility to set the ssl_ca_certificate configuration parameter for intelmq.bots.collectors.stomp.collector and/or intelmq.bots.outputs.stomp.output to an empty string - which means that the SSL machinery used for STOMP communication will attempt to load the system’s default CA certificates (PR#2414 by Jan Kaliszewski).

  • Variable _common_keys is moved out of the class.
  • _dict_dict_to_obj_list is introduced, for converting a string-to-dict mapping into a list of dicts with the previous key as an attribute of the dict; this can be useful for preventing issues where, when feeding the data into aggregating tools, you'd end up with many more fields than necessary, e.g vulns.CVE-2010-0001.cvss, CVE-2010-0002.cvss etc.
  • _get_first to get the first item from a list, with NoValueException raised on empty lists.

  • Fix Autoshun Feed URL (#1325).
  • Add parameters name and provider to intelmq/etc/feeds.yaml, docs/Feeds.md and intelmq/bots/BOTS (#1321).
  • Add SECURITY.md file.

Packaging

  • Change the maintainer from Sasche Wilde to Sebastian Wagner (#1320).

Tests

  • intelmq.tests.lib.test_bot: Skip test_logging_level_other on python 3.7 because of unclear behavior related to copies of loggers (#1269).
  • intelmq.tests.bots.collectors.rt.test_collector: Remove test because the REST interface of the instance has been closed (see also https://github.com/CZ-NIC/python-rt/issues/28).

Tools

  • intelmqctl check: Shows more detailed information on orphaned queues.
  • intelmqctl:
  • Correctly determine the status of bots started with intelmqctl run.
  • Fix output of errors during bot status determination, making it compatible to IntelMQ Manager.
  • check subcommand: Show bot ID for messages also in JSON output.
  • run [bot-id] process -m [message] works also with bots without a configured source pipeline (#1307).

Contrib

  • elasticsearch/elasticmapper: Add tlp field (#1308).
  • feeds-config-generator/intelmq_gen_feeds_conf:
  • Add parameters to write resulting configuration directly to files (#1321).
  • Handle collector's feed.name and feed.provider (#1314).

Known issues

  • Bots started with IntelMQ-Manager stop when the webserver is restarted (#952).
  • Tests: capture logging with context manager (#1342).
  • stomp collector bot constantly uses 100% of CPU (#1364).

1.1.0 (2018-09-05)

  • Support for Python 3.3 has been dropped in IntelMQ and some dependencies of it. Python 3.3 reached its end of life and Python 3.4 or newer is a hard requirement now.
  • The list of feeds docs/Feeds.md has now a machine-readable equivalent YAML file in intelmq/etc/feeds.yaml A tool to convert from yaml to md has been added.

Tools

  • intelmq_gen_feeds_docs added to bin directory, allows generating the Feeds.md documentation file from feeds.yaml
  • intelmq_gen_docs merges both intelmq_gen_feeds_docs and intelmq_gen_harm_docs in one file and automatically updates the documentation files.

intelmqctl

  • intelmqctl start prints the bot's last error messages if the bot failed to start (#1021).
  • intelmqctl start message "is running" is printed every time. (Until now, it wasn't said when a bot was just starting.)
  • intelmqctl start/stop/restart/reload/status now has a "--group" flag which allows you to specify the group of the bots that should be influenced by the command.
  • intelmqctl check checks for defaults.conf completeness if the shipped file from the package can be found.
  • intelmqctl check shows errors for non-importable bots.
  • intelmqctl list bots -q only prints the IDs of enabled bots.
  • intelmqctl list queues-and-status prints both queues and bots statuses (so that it can be used in eg. intelmq-manager).
  • intelmqctl run parameter for showing a sent message.
  • intelmqctl run if message is sent to a non-default path, it is printed out.
  • intelmqctl restart bug fix; returned some half-nonsense, now returns return state of start and stop operation in a list (#1226).
  • intelmqctl check: New parameter --no-connections to prevent the command from making connections e.g. to the redis pipeline.s
  • intelmqctl list queues: don't display named paths among standard queues.
  • The process status test failed if the PATH did not include the bot executables and the which command failed. Then the proccess's command line could not be compared correctly. The fix warns of this and adds a new status 'unknown' (#1297).

Contrib

  • tool feeds-config-generator to automatically generate the collector and parser runtime and pipeline configurations.
  • malware_name_mapping: Download and convert tool for malware family name mapping has been added.
  • Added a systemd script which creates systemd units for bots (#953).
  • contrib/cron-jobs/update-asn-data, contrib/cron-jobs/update-geoip-data, contrib/cron-jobs/update-tor-nodes: Errors produce proper output.

Core

  • lib/bot
  • use SIGTERM instead of SIGINT to stop bots (#981).
  • Bots can specify a static method check(parameters) which can perform individual checks specific to the bot. These functions will be called by intelmqctl check if the bot is configured with the given parameters
  • top level bot parameters (description, group, module, name) are exposed as members of the class.
  • The parameter feed for collectors is deprecated for 2.0 and has been replaced by the more consistent name (#1144).
  • bug: allow path parameter for CollectorBot class.
  • Handle errors better when the logger could not be initialized.
  • ParserBot:
    • For the csv parsing methods, ParserBot.csv_params is now used for all these methods.
    • ParserBot.parse_csv_dict now saves the field names in ParserBot.csv_fieldnames.
    • ParserBot.parse_csv_dict now saves the raw current line in ParserBot.current_line.
    • ParserBot.recover_line_csv_dict now uses the raw current line.
  • lib/message:
  • Subitems in fields of type JSONDict (see below) can be accessed directly. E.g. you can do: event['extra.foo'] = 'bar' event['extra.foo'] # gives 'bar' It is still possible to set and get the field as whole, however this may be removed or changed in the future: event['extra'] = '{"foo": "bar"}' event['extra'] # gives '{"foo": "bar"}' "Old" bots and configurations compatible with 1.0.x do still work. Also, the extra field is now properly exploded when exporting events, analogous to all other fields. The in operator works now for both - the old and the new - behavior.
  • Message.add: The parameter overwrite accepts now three different values: True, False and None (new). True: An existing value will be overwritten False: An existing value will not be overwritten (previously an exception has been raised when the value was given). None (default): If the value exists an KeyExists exception is thrown (previously the same as False). This allows shorter code in the bots, as an 'overwrite' configuration parameter can be directly passed to the function.
  • The message class has now the possibility to return a default value for non-existing fields, see Message.set_default_value.
  • Message.get behaves the same like Message.__getitem__ (#1305).
  • Add RewindableFileHandle to utils making handling of CSV files more easy (optionally)
  • lib/pipeline:
  • you may now define more than one destination queues path the bot should pass the message to, see Pipelines (#1088, #1190).
  • the special path "_on_error" can be used to pass messages to different queues in case of processing errors (#1133).
  • lib/harmonization: Accept AS prefix for ASN values (automatically stripped).
  • added intelmq.VAR_STATE_PATH for variable state data of bots.

Bots

  • Removed print statements from various bots.
  • Replaced various occurrences of self.logger.error() + self.stop() with raise ValueError.

Short history

In 2013 and 2014 Aaron Kaplan (back then working at CERT.at) was researching ways to improve the automation of handling and distributing (IT security) incident reports across a whole country as part of the job of a national CERT. We would get many notifications of vulnerable systems, hacked systems, phishing domains, etc etc. The amount of reports we were getting required an automated solution. Back then, Aaron and a couple of other people looked at a tool called "Abusehelper". There was an open source version of Abusehelper, but it was deemed quite complex and complicated at that time.

Frustration with this tool led to discussions amongst multiple CERTs.

The idea and overall concept of an free, truly open source, simple (KISS principle! Keep it simple, stupid) community owned and maintained, extendible software for automated incident handling was born at an meeting of several European CSIRTs in Heraklion, Greece, in 2014. Following the event, Tomás Lima "SYNchroACK" (working at CERT.pt back then) created IntelMQ from scratch. IntelMQ was born on June 24th, 2014. A major support came from CERT.pt at this early stage. Aaron Kaplan (CERT.at until 2020) engaged in the long-term advancement and from 2015 on, CERT.at took the burden of the maintenance and development (Sebastian Wagner 2015-2021 at CERT.at). From 2016 onward, CERT.at started projects, initiated and lead by Aaron Kaplan, receiving CEFF-funding from the European Union to support IntelMQ's development. IntelMQ became a software component of the EU-funded MeliCERTes framework for CSIRTs. In 2020, IntelMQ's organizational structure and architectural development gained new thrive by the newly founded Board and the start of the IEP process, creating more structure and more transparency in the IntelMQ community's decisions.

Adding Feeds

Adding a feed doesn't necessarily require any programming experience. There are several collector and parser bots intended for general use. Depending on the data source you are trying to add as a feed, it might be only a matter of creating a working combination of collector bot (such as URL Fetcher) configuration and a parser bot (such as CSV parser) configuration. When you are satisfied with the configurations, add it to the intelmq/etc/feeds.yaml file using the following template and open a pull request!

If the data source utilizes some unusual way of distribution or uses a custom format for the data it might be necessary to develop specialized bot(s) for this particular data source. Always try to use existing bots before you start developing your own. Please also consider extending an existing bot if your use-case is close enough to it's features. If you are unsure which way to take, start an issue and you will receive guidance.

Feeds Wishlist

This is a list with potentially interesting data sources, which are either currently not supported or the usage is not clearly documented in IntelMQ. If you want to contribute new feeds to IntelMQ, this is a great place to start!

Note

Some of the following data sources might better serve as an expert bot for enriching processed events.

Bot Development

Here you should find everything you need to develop a new bot.

Steps

  1. Create appropriately placed and named python file.
  2. Use correct parent class.
  3. Code the functionality you want (with mixins, inheritance, etc).
  4. Create appropriately placed test file.
  5. Prepare code for testing your bot.
  6. Add documentation for your bot.
  7. Add changelog and news info.

When calling the file directly, only the tests in this file for the bot will be expected. Some default tests are always executed (via the test.BotTestCase class), such as pipeline and message checks, logging, bot naming or empty message handling.

See the testing section about how to run the tests.

Cache

Bots can use a Redis database as cache instance. Use the intelmq.lib.utils.Cache class to set this up and/or look at existing bots, like the cymru_whois expert how the cache can be used. Bots must set a TTL for all keys that are cached to avoid caches growing endless over time. Bots must use the Redis databases >= 10, but not those already used by other bots. Look at find intelmq -type f -name '*.py' -exec grep -r 'redis_cache_db' {} + to see which databases are already used.

The databases < 10 are reserved for the IntelMQ core:

  • 2: pipeline
  • 3: statistics
  • 4: tests

Documentation

Please document your added/modified code.

For doc strings, we are using the sphinx-napoleon-google-type-annotation.

Additionally, Python's type hints/annotations are used, see PEP484.

Testing Pre-releases

Installation

The installation procedures need to be adapted only a little bit.

For native packages, you can find the unstable packages of the next version here: Installation Unstable Native Packages . The unstable only has a limited set of packages, so enabling the stable repository can be activated in parallel. For CentOS 8 unstable, the stable repository is required.

For the installation with pip, use the --pre parameter as shown here following command:

pip3 install --pre intelmq

Skip to content
certtools/intelmq

Data Format

Data passed between bots is called a Message. There are two types of Messages: Report and Event. Report is produced by collector bots and consists of collected raw data (CSV, JSON, HTML, etc) and feed metadata. It is passed to a parser bot which parses Report into a single or multiple Events. Expert bots and output bots handle only Events.

All Messages (Reports and Events) are Python dictionaries (or JSONs). The key names and according types are defined by the IntelMQ Data Format.

The source code for the Data Format can be found in the Python module intelmq.lib.harmonization and the configuration is present inside the harmonization.conf file. (The term Harmonization is used for historical reasons.)

Rules for keys

The keys are grouped together in sub-fields, e.g. source.ip or source.geolocation.latitude.

Only the lower-case alphabet, numbers and the underscore are allowed. Further, the field name must not begin with a number. Thus, keys must match ^[a-z_][a-z_0-9]+(\.[a-z_0-9]+)*$. These rules also apply for the otherwise unregulated extra. namespace.

Data Types

This document describes the IntelMQ data types used for individual events with a description of each allowed field.

ASN

ASN type. Derived from Integer with forbidden values.

Only valid are: 0 < ASN <= 4294967295

See https://en.wikipedia.org/wiki/Autonomous_system_(Internet)

The first and last ASNs of the original 16-bit integers, namely 0 and 65,535, and the last ASN of the 32-bit numbers, namely 4,294,967,295 are reserved and should not be used by operators.

Accuracy

Accuracy type. A Float between 0 and 100.

Base64

Base64 type. Always gives unicode strings.

Sanitation encodes to base64 and accepts binary and unicode strings.

Boolean

Boolean type. Without sanitation only python bool is accepted.

Sanitation accepts string 'true' and 'false' and integers 0 and 1.

ClassificationTaxonomy

classification.taxonomy type.

The mapping follows Reference Security Incident Taxonomy Working Group – RSIT WG: https://github.com/enisaeu/Reference-Security-Incident-Taxonomy-Task-Force/

These old values are automatically mapped to the new ones:

  • 'abusive content' -> 'abusive-content'
  • 'information gathering' -> 'information-gathering'
  • 'intrusion attempts' -> 'intrusion-attempts'
  • 'malicious code' -> 'malicious-code'

Allowed values are:

  • availability
  • fraud
  • information-content-security
  • information-gathering
  • intrusion-attempts
  • intrusions

DateTime

Date and time type for timestamps.

Valid values are timestamps with time zone and in the format '%Y-%m-%dT%H:%M:%S+00:00'. Invalid are missing times and missing timezone information (UTC). Microseconds are also allowed.

Sanitation normalizes the timezone to UTC, which is the only allowed timezone.

The following additional conversions are available with the convert function:

  • timestamp
  • windows_nt: From Windows NT / AD / LDAP
  • epoch_millis: From Milliseconds since Epoch
  • from_format: From a given format, eg. 'from_format|%H %M %S %m %d %Y %Z'
  • from_format_midnight: Date from a given format and assume midnight, e.g. 'from_format_midnight|%d-%m-%Y'
  • utc_isoformat: Parse date generated by datetime.isoformat()
  • fuzzy (or None): Use dateutils' fuzzy parser, default if no specific parser is given

FQDN

Fully qualified domain name type.

All valid lowercase domains are accepted, no IP addresses or URLs. Trailing dot is not allowed.

To prevent values like '10.0.0.1:8080' (#1235), we check for the non-existence of ':'.

Float

Float type. Without sanitation only python float/integer/long is accepted. Boolean is explicitly denied.

Sanitation accepts strings and everything float() accepts.

IPAddress

Type for IP addresses, all families. Uses the ipaddress module.

Sanitation accepts integers, strings and objects of ipaddress.IPv4Address and ipaddress.IPv6Address.

Valid values are only strings. 0.0.0.0 is explicitly not allowed.

IPNetwork

Type for IP networks, all families. Uses the ipaddress module.

Sanitation accepts strings and objects of ipaddress.IPv4Network and ipaddress.IPv6Network. If host bits in strings are set, they will be ignored (e.g 127.0.0.1/32).

Valid values are only strings.

Integer

Integer type. Without sanitation only python integer/long is accepted. Bool is explicitly denied.

Sanitation accepts strings and everything int() accepts.

JSON

JSON type.

Sanitation accepts any valid JSON objects.

Valid values are only unicode strings with JSON objects.

JSONDict

JSONDict type.

Sanitation accepts pythons dictionaries and JSON strings.

Valid values are only unicode strings with JSON dictionaries.

LowercaseString

Like string, but only allows lower case characters.

Sanitation lowers all characters.

Registry

Registry type. Derived from UppercaseString.

Only valid values: AFRINIC, APNIC, ARIN, LACNIC, RIPE. RIPE-NCC and RIPENCC are normalized to RIPE.

String

Any non-empty string without leading or trailing whitespace.

TLP

TLP level type. Derived from UppercaseString.

Only valid values: WHITE, GREEN, AMBER, RED.

Accepted for sanitation are different cases and the prefix 'tlp:'.

URL

URI type. Local and remote.

Sanitation converts hxxp and hxxps to http and https. For local URIs (file) a missing host is replaced by localhost.

Valid values must have the host (network location part).

UppercaseString

Like string, but only allows upper case characters.

Sanitation uppers all characters.

  • your package registers an entry point in the console_scripts group with a name starting with intelmq.bots. followed by the name of the group (collectors, experts, outputs, parsers), and then your original name. The entry point must point to the BOT.run method,
  • the module in which the bot resides must be importable by IntelMQ (e.g. installed in the same virtualenv, if you use them).

Apart from these requirements, your package can use any of the usual package features. We strongly recommend following the same principles and main guidelines as the official bots. This will ensure the same experience when using official and additional bots.

Naming convention

Building your own extensions gives you a lot of freedom, but it's important to know that if your bot's entry point uses the same name as another bot, it may not be possible to use it, or to determine which one is being used. For this reason, we recommend that you start the name of your bot with an with an organization identifier and then the bot name.

For example, if I create a collector bot for feed source Special and run it on behalf of the organization Awesome, the suggested entry point might be intelmq.bots.collectors.awesome.special. Note that the structure of your package doesn't matter, as long as it can be imported properly.

For example, I could create a package called awesome-bots with the following file structure

   awesome_bots
@@ -18,6 +18,6 @@
         └── special.py

The pyproject.toml file would then have the following section:

   [project.scripts]
    intelmq.bots.collectors.awesome.special = "awesome_bots.special:BOT.run"
-

Once you have installed your package, you can run intelmqctl list bots to check if your bot was properly registered.

Development Guidelines

Coding-Rules

Most important: KEEP IT SIMPLE! This can not be over-estimated. Feature creep can destroy any good software project. But if new folks can not understand what you wrote in 10-15 minutes, it is not good. It's not about the performance, etc. It's about readability.

In general, we follow PEP8. We recommend reading it before committing code.

There are some exceptions: sometimes it does not make sense to check for every PEP8 error (such as whitespace indentation when you want to make a dict=() assignment look pretty. Therefore, we do have some exceptions defined in the setup.cfg file.

We support Python 3 only.

Unicode

  • Each internal object in IntelMQ (Event, Report, etc) that has strings, their strings MUST be in UTF-8 Unicode format.
  • Any data received from external sources MUST be transformed into UTF-8 Unicode format before add it to IntelMQ objects.

Back-end independence and Compatibility

Any component of the IntelMQ MUST be independent of the message queue technology (Redis, RabbitMQ, etc...).

License Header

Please add a license and copyright header to your bots. There is a Github action that tests for reuse compliance of your code files.

IntelMQ Data Format Rules

Any component of IntelMQ MUST respect the IntelMQ Data Format.

Code Submission Rules

Releases, Repositories and Branches

  • The main repository is in github.com/certtools/intelmq.
  • We use semantic versioning.
  • If you contribute something, please fork the repository, create a separate branch and use this for pull requests, see section below.
  • There are a couple of forks which might be regularly merged into the main repository. They are independent and can have incompatible changes and can deviate from the upstream repository.

Branching model

  • "master" is the stable branch. It hold the latest stable release. Non-developers should only work on this branch. The recommended log level is WARNING. Code is only added by merges from the maintenance branches.
  • "maintenance/a.b.x" branches accumulate (cherry-picked) patches for a maintenance release (a.b.x). Recommended for experienced users which deploy intelmq themselves. No new features will be added to these branches.
  • "develop" is the development branch for the next stable release (a.x). New features must go there. Developers may want to work on this branch. This branch also holds all patches from maintenance releases if applicable. The recommended log level is DEBUG.
  • Separate branches to develop features or bug fixes may be used by any contributor.

How to Contribute

  • Make separate pull requests / branches on GitHub for changes. This allows us to discuss things via GitHub.
  • We prefer one Pull Request per feature or change. If you have a bunch of small fixes, please don't create one PR per fix :)
  • Only very small and changes (docs, ...) might be committed directly to development branches without Pull Request by the core-team.
  • Keep the balance between atomic commits and keeping the amount of commits per PR small. You can use interactive rebasing to squash multiple small commits into one (rebase -i [base-branch]). Only do rebasing if the code you are rebasing is yet not used by others or is already merged - because then others may need to run into conflicts.
  • Make sure your PR is merge able in the develop branch and all tests are successful.
  • If possible sign your commits with GPG.

Workflow

We assume here, that origin is your own fork. We first add the upstream repository:

 git remote add upstream https://github.com/certtools/intelmq.git
@@ -30,6 +30,6 @@
 git rebase develop

Using the -i flag for rebase enables interactive rebasing. You can then remove, reorder and squash commits, rewrite commit messages, beginning with the given branch, e.g. develop.

Or using merging. This doesn't break the history. It's considered more , but also pollutes the history with merge commits.

git checkout bugfix
 git merge develop
-

You can then create a PR with your branch bugfix to our upstream repository, using GitHub's web interface.

Commit Messages

If it fixes an existing issue, please use GitHub syntax, e.g.: fixes certtools/intelmq#<IssueID>

Prepare for Discussion in GitHub

If we don't discuss it, it's probably not tested.

License and Author files

License and Authors files can be found at the root of repository.

  • License file MUST NOT be modified except by the explicit written permission by CNCS/CERT.PT or CERT.at
  • Credit to the authors file must be always retained. When a new contributor (person and/or organization) improves in some way the repository content (code or documentation), he or she might add his name to the list of contributors.

License and authors must be only listed in an external file but not inside the code files.

Intro

This guide is for developers of IntelMQ. It explains the code architecture, coding guidelines as well as ways you can contribute code or documentation. If you have not done so, please read the User Guide and the Administrator Guide first. Once you feel comfortable running IntelMQ with open source bots and you feel adventurous enough to contribute to the project, this guide is for you. It does not matter if you are an experienced Python programmer or just a beginner. There is a lot of examples to help you out.

However, before we go into the details, it is important to observe and internalize some overall project goals.

Goals

It is important, that all developers agree and stick to these meta-guidelines. IntelMQ tries to:

  • Be well tested. For developers this means, we expect you to write unit tests for bots. Every time.
  • Reduce the complexity of system administration.
  • Reduce the complexity of writing new bots for new data feeds.
  • Make your code easily and pleasantly readable.
  • Reduce the probability of events lost in all process with persistence functionality (even system crash).
  • Strictly adhere to the existing format for keys and values in events.
  • Always use JSON format for all messages internally.
  • Help and support the interconnection between IntelMQ and existing tools like AbuseHelper, CIF, etc. or new tools (in other words: we will not accept data-silos!).
  • Provide an easy way to store data into log collectors such as ElasticSearch or Splunk.
  • Provide an easy way to create your own black-lists.
  • Provide easy to understand interfaces with other systems via HTTP RESTFUL API.

The main take away point from the list above is: things MUST stay intuitive and easy. How do you ultimately test if things are still easy? Let them new programmers test-drive your features and if it is not understandable in 15 minutes, go back to the drawing board.

Similarly, if code does not get accepted upstream by the main developers, it is usually only because of the ease-of-use argument. Do not give up, go back to the drawing board, and re-submit again.

Mailing list

There is a separate mailing list for developers to discuss development topics: The IntelMQ-DevArchive is public as well.

GitHub

The ideal way to propose changes and additions to IntelMQ is to open a Pull Request on GitHub.

Release procedure

General assumption: You are working on branch maintenance, the next version is a bug fix release. For feature releases it is slightly different.

Check before

  • Make sure the current state is really final ;) You can test most of the steps described here locally before doing it real.
  • Check the upgrade functions in intelmq/lib/upgrades.py.
  • Close the milestone on GitHub and move any open issues to the next one.
  • docs/admin/installation/linux-packages.md: Update supported operating systems.

Documentation

These apply to all projects:

  • CHANGELOG.MD and NEWS.MD: Update the latest header, fix the order, remove empty sections and (re)group the entries if necessary.
  • debian/changelog: Insert a new section for the new version with the tool dch or update the version of the existing last item if yet unreleased. Don't forget the revision after the version number!

IntelMQ

  • intelmq/version.py: Update the version.

Eventually adapt the default log levels if necessary. Should be INFO for stable releases.

IntelMQ API

  • intelmq_api/version.py: Update the version.

IntelMQ Manager

  • intelmq_manager/version.py: Update the version.
  • intelmq_manager/static/js/about.js: Update the version.

Commit, push, review and merge

Commit your changes in a separate branch, the final commit message should start with REL:. Push and create a pull request to the develop branch. Someone else should review the changes. Eventually fix them, make sure the REL: is the last commit, you can also push that one at last, after the reviews.

Why a separate branch? Because if problems show up, you can still force-push to that one, keeping the release commit the latest one.

Tag and release

Tag the commit with git tag -s version HEAD, merge it into develop, push the branches and the tag. The tag is just a.b.c, not prefixed with v (that was necessary only with SVN a long time ago...).

Go to https://github.com/certtools/intelmq/tags and enter the release notes (from the CHANGELOG) for the new tag, then it's considered a release by GitHub.

System Overview

In the intelmq/lib/ directory you can find some libraries:

  • Bots: Defines base structure for bots and handling of startup, stop, messages etc.
  • Cache: For some expert bots it does make sense to cache external lookup results. Redis is used here.
  • Harmonization: For defined types, checks and sanitation methods are implemented.
  • Message: Defines Events and Reports classes, uses harmonization to check validity of keys and values according to config.
  • Pipeline: Writes messages to message queues. Implemented for productions use is only Redis, AMQP is beta.
  • Test: Base class for bot tests with predefined test and assert methods.
  • Utils: Utility functions used by system components.

There are multiple GitHub Action Workflows setup for automatic testing, which are triggered on pull requests. You can also easily activate them for your forks.

Environment variables

There are a bunch of environment variables which switch on/off some tests:

Environment Variable Name Description
INTELMQ_TEST_DATABASES databases such as postgres, elasticsearch, mongodb are not tested by default. Set this environment variable to 1 to test those bots. These tests need preparation, e.g. running databases with users and certain passwords etc. Have a look at the .github/workflows/unittests.yml and the corresponding .github/workflows/scripts/setup-full.sh in IntelMQ's repository for steps to set databases up.
INTELMQ_SKIP_INTERNET tests requiring internet connection will be skipped if this is set to 1.
INTELMQ_SKIP_REDIS redis-related tests are ran by default, set this to 1 to skip those.
INTELMQ_TEST_EXOTIC some bots and tests require libraries which may not be available, those are skipped by default. To run them, set this to 1.
INTELMQ_TEST_REDIS_PASSWORD Set this value to the password for the local redis database if needed.
INTELMQ_LOOKYLOO_TEST Set this value to run the lookyloo tests. Public lookyloo instance will be used as default.
INTELMQ_TEST_INSTALLATION Set this value to run tests which require a local IntelMQ installation, such as for testing the command lines tools relying on configuration files, dump files etc.

For example, to run all tests you can use:

Configuration test files

The tests use the configuration files in your working directory, not those installed in /opt/intelmq/etc/ or /etc/. You can run the tests for a locally changed intelmq without affecting an installation or requiring root to run them.

Getting help

In case you are lost, you need assistance or something is not discussed in this guide, you can ask the community for help. To be most efficient in seeking help, please describe your problem or question with all necessary information, for example:

  • Name and version of the operating system
  • Way of installation (deb/rpm packages, PyPI, docker, local git repository)
  • Used bots and configuration
  • Logs of bots or terminal output
  • Any other useful messages, screenshots

Please report any errors and suggest improvements via issues. Thank you!

GitHub

GitHub offers a discussion platform where you can ask questions and seek assistance.

To report bugs, GitHub issues are the ideal place to do so. Every IntelMQ component has it's own repository on GitHub, with a separate Issue tracker.

To participate on GitHub, you first need to create an account on the platform.

Mailing list

The most traditional way is to ask your question, make a proposal or discuss a topic on the mailing IntelMQ Users mailing list. You need to subscribe to the mailing list before posting, but the archive is publicly available: IntelMQ Users Archive.

Assistance

If your organisation is a member of the CSIRTs Network, you are eligible for support in the MeliCERTes project. You can also ask on for individual support, some members offer support, including, but not limited to:

IntelMQ

Introduction

IntelMQ is a solution for IT security teams (CERTs & CSIRTs, SOCs abuse departments, etc.) for collecting and processing security feeds (such as log files) using a message queuing protocol. It's a community driven initiative called IHAP1 (Incident Handling Automation Project) which was conceptually designed by European CERTs/CSIRTs during several InfoSec events. Its main goal is to give to incident responders an easy way to collect & process threat intelligence thus improving the incident handling processes of CERTs.

IntelMQ is frequently used for:

  • automated incident handling
  • situational awareness
  • automated notifications
  • as data collector for other tools
  • and more!

The design was influenced by AbuseHelper however it was re-written from scratch and aims at:

  • Reducing the complexity of system administration
  • Reducing the complexity of writing new bots for new data feeds
  • Reducing the probability of events lost in all process with persistence functionality (even system crash)
  • Use and improve the existing Data Harmonization Ontology
  • Use JSON format for all messages
  • Provide easy way to store data into databases and log collectors such as PostgreSQL, Elasticsearch and Splunk
  • Provide easy way to create your own black-lists
  • Provide easy communication with other systems via HTTP RESTful API

It follows the following basic meta-guidelines:

  • Don't break simplicity - KISS
  • Keep it open source - forever
  • Strive for perfection while keeping a deadline
  • Reduce complexity/avoid feature bloat
  • Embrace unit testing
  • Code readability: test with inexperienced programmers
  • Communicate clearly

Additional tools

Here you can find a list of additional tools. If you think something is missing, please let us know!

Unless stated otherwise, the tools are maintained by the IntelMQ community.

IntelMQ Webinput CSV

A web-based interface to ingest CSV data into IntelMQ with on-line validation and live feedback.

This interface allows inserting "one-shot" data feeds into IntelMQ without the need to configure bots in IntelMQ.

Developed and maintained by CERT.at.

→ Repository: intelmq-webinput-csv

IntelMQ Mailgen

A solution allowing an IntelMQ setup with a complex contact database, managed by a web interface and sending out aggregated email reports. In different words: To send grouped notifications to network owners using SMTP.

Developed and maintained by Intevation, initially funded by BSI.

It consists of the following three components, which can also be used on their own.

IntelMQ CertBUND Contact

The certbund-contact consists of two IntelMQ expert bots, which fetch and process the information from the contact database, and scripts to import RIPE data into the contact database. Based on user-defined rules, the experts determine to which contact the event is to be sent to, and which e-mail template and attachment format to use.

→ Repository: intelmq-certbund-contact

IntelMQ Fody

Fody is a web based interface for Mailgen. It allows to read and edit contacts, query sent mails (tickets) and call up data from the PostgreSQL database.

It can also be used to just query the database without using Mailgen.

IntelMQ Fody Dashboard

→ Repository: intelmq-fody

→ Repository: intelmq-fody-backend

intelmq-mailgen

Sends emails with grouped event data to the contacts determined by the certbund-contact. Mails can be encrypted with PGP.

→ Repository: intelmq-mailgen

"Constituency Portal" tuency

A web application helping CERTs to enable members of their constituency to self-administrate how they get warnings related to their network objects (IP addresses, IP ranges, autonomous systems, domains). tuency is developed by Intevation for CERT.at.

If features organizational hierarchies, contact roles, self-administration and network objects per organization (Autonomous systems, network ranges, (sub)domains, RIPE organization handles). A network object claiming and approval process prevents abuse. An hierarchical rule-system on the network objects allow fine-grained settings. The tagging system for contacts and organization complement the contact-management features of the portal. Authentication is based on keycloak, which enables the re-use of the user accounts in the portal. The integrated API enables IntelMQ to query the portal for the right abuse contact and notification settings with the intelmq.bots.experts.tuency.expert expert bot.

In 2013 and 2014 Aaron Kaplan (back then working at CERT.at) was researching ways to improve the automation of handling and distributing (IT security) incident reports across a whole country as part of the job of a national CERT. We would get many notifications of vulnerable systems, hacked systems, phishing domains, etc etc. The amount of reports we were getting required an automated solution. Back then, Aaron and a couple of other people looked at a tool called \"Abusehelper\". There was an open source version of Abusehelper, but it was deemed quite complex and complicated at that time.

Frustration with this tool led to discussions amongst multiple CERTs.

The idea and overall concept of an free, truly open source, simple (KISS principle! Keep it simple, stupid) community owned and maintained, extendible software for automated incident handling was born at an meeting of several European CSIRTs in Heraklion, Greece, in 2014. Following the event, Tom\u00e1s Lima \"SYNchroACK\" (working at CERT.pt back then) created IntelMQ from scratch. IntelMQ was born on June 24th, 2014. A major support came from CERT.pt at this early stage. Aaron Kaplan (CERT.at until 2020) engaged in the long-term advancement and from 2015 on, CERT.at took the burden of the maintenance and development (Sebastian Wagner 2015-2021 at CERT.at). From 2016 onward, CERT.at started projects, initiated and lead by Aaron Kaplan, receiving CEFF-funding from the European Union to support IntelMQ's development. IntelMQ became a software component of the EU-funded MeliCERTes framework for CSIRTs. In 2020, IntelMQ's organizational structure and architectural development gained new thrive by the newly founded Board and the start of the IEP process, creating more structure and more transparency in the IntelMQ community's decisions.

Warning

Do not use it in production environments yet! It has not been tested thoroughly yet.

Supervisor is process manager written in Python. The main advantage is that it take care about processes, so if bot process exit with failure (exit code different than 0), supervisor try to run it again. Another advantage is that it not require writing PID files.

This was tested on Ubuntu 18.04.

Install supervisor. supervisor_twiddler is extension for supervisor, that makes possible to create process dynamically. (Ubuntu supervisor package is currently based on Python 2, so supervisor_twiddler must be installed with Python 2 pip.)

apt install supervisor python-pip\npip install supervisor_twiddler\n

Create default config /etc/supervisor/conf.d/intelmq.conf and restart supervisor service:

[rpcinterface:twiddler]\nsupervisor.rpcinterface_factory=supervisor_twiddler.rpcinterface:make_twiddler_rpcinterface\n\n[group:intelmq]\n

Change IntelMQ process manager in the global configuration:

process_manager: supervisor\n

After this it is possible to manage bots like before with intelmqctl command.

"},{"location":"admin/beta-features/#using-amqp-message-broker","title":"Using AMQP Message Broker","text":"

Starting with IntelMQ 1.2 the AMQP protocol is supported as message queue. To use it, install a broker, for example RabbitMQ. The configuration and the differences are outlined here. Keep in mind that it is slower, but has better monitoring capabilities and is more stable. The AMQP support is considered beta, so small problems might occur. So far, only RabbitMQ as broker has been tested.

You can change the broker for single bots (set the parameters in the runtime configuration per bot) or for the whole botnet (using the global configuration).

You need to set the parameter source_pipeline_broker/destination_pipeline_broker to amqp. There are more parameters available:

Bug

This section of the documentation is currently incomplete and will be updated later.

source_pipeline_amqp_virtual_host

() (default: '/')

intelmqctl_rabbitmq_monitoring_url

() string, see below (default: \"http://{host}:15672\")

For getting the queue sizes, intelmqctl needs to connect to the monitoring interface of RabbitMQ. If the monitoring interface is not available under http://{host}:15672 you can manually set using the parameter intelmqctl_rabbitmq_monitoring_url. In a RabbitMQ's default configuration you might not provide a user account, as by default the administrator (guest:guest) allows full access from localhost. If you create a separate user account, make sure to add the tag \"monitoring\" to it, otherwise IntelMQ can't fetch the queue sizes.

Setting the statistics (and cache) parameters is necessary when the local redis is running under a non-default host/port. If this is the case, you can set them explicitly:

statistics_database

() 3

statistics_host

() \"127.0.0.1\"

statistics_password

() null

Yes, you can install the API and the Manager from the deb/rpm repositories, and install your IntelMQ from a somewhere else, e.g. a local repository. However, knowledge about Python and system administration experience is recommended if you do so.

The packages install IntelMQ to /usr/lib/python3*/site-packages/intelmq/. Installing with pip results in /usr/local/lib/python3*/site-packages/intelmq/ (and some other accompaning resources) which overrides the installation in /usr/lib/.

Before Multithreading was available in IntelMQ, and in case you use Redis as broker, the only way to do load balancing involves more work. Create multiple instances of the same bot and connect them all to the same source and destination bots. Then set the parameter load_balance to true for the bot which sends the messages to the duplicated bot. Then, the bot sends messages to only one of the destination queues and not to all of them.

True Multiprocessing is not available in IntelMQ. See also this discussion on a possible enhanced load balancing <186>.

"},{"location":"admin/faq/#other-options","title":"Other options","text":"

For any bottleneck based on (online) lookups, optimize the lookup itself and if possible use local databases.

It is also possible to use multiple servers to spread the workload. To get the messages from one system to the other you can either directly connect to the other's pipeline or use a fast exchange mechanism such as the TCP Collector/Output (make sure to secure the network by other means).

"},{"location":"admin/faq/#removing-raw-data-for-higher-performance-and-less-space-usage","title":"Removing raw data for higher performance and less space usage","text":"

If you do not need the raw data, you can safely remove it. For events (after parsers), it keeps the original data, eg. a line of a CSV file. In reports it keeps the actual data to be parsed, so don't delete the raw field in Reports - between collectors and parsers.

The raw data consumes about 50% - 30% of the messages' size. The size of course depends on how many additional data you add to it and how much data the report includes. Dropping it, will improve the speed as less data needs to be transferred and processed at each step.

In a bot

You can do this for example by using the Field Reducer Expert. The configuration could be:

Other solutions are the Modify bot and the Sieve bot. The last one is a good choice if you already use it and you only need to add the command:

remove raw\n

In the database

In case you store data in the database and you want to keep its size small, you can (periodically) delete the raw data there.

To remove the raw data for a events table of a PostgreSQL database, you can use something like:

UPDATE events SET raw = NULL WHERE \"time.source\" < '2018-07-01';\n

If the database is big, make sure only update small parts of the database by using an appropriate WHERE clause. If you do not see any negative performance impact, you can increase the size of the chunks, otherwise the events in the output bot may queue up. The id column can also be used instead of the source's time.

Another way of reducing the raw-data from the database is described in the EventDB documentation: eventdb_raws_table.

Do you ask yourself how much RAM do you need to give your new IntelMQ virtual machine?

The honest answer is simple and pointless: It depends ;)

"},{"location":"admin/hardware-requirements/#intelmq-and-the-messaging-queue-broker","title":"IntelMQ and the messaging queue (broker)","text":"

IntelMQ uses a messaging queue to move the messages between the bots. All bot instances can only process one message at a time, therefore all other messages need to wait in the queue. As not all bots are equally fast, the messages will naturally \"queue up\" before the slower ones. Further, parsers produce many events with just one message (the report) as input.

The following estimations assume Redis as messaging broker which is the default for IntelMQ. When RabbitMQ is used, the required resources will differ, and RabbitMQ can handle system overload and therefore a shortage of memory.

As Redis stores all data in memory, the data which is processed at any point in time must fit there, including overheads. Please note that IntelMQ does neither store nor cache any input data. These estimates therefore only relate to the processing step, not the storage.

For a minimal system, these requirements suffice:

Depending on your data input, you will need the twentiethfold of the input data size as memory for processing.

When using Redis persistence, you will additionally need twice as much memory for Redis.

"},{"location":"admin/hardware-requirements/#disk-space","title":"Disk space","text":"

Disk space is only relevant if you save your data to a file, which is not recommended for production setups, and only useful for testing and evaluation.

Do not forget to rotate your logs or use syslog, especially if you use the logging level \"DEBUG\". logrotate is in use by default for all installation with deb/rpm packages. When other means of installation are used (pip, manual), configure log rotation manually. See logging configuration.

"},{"location":"admin/hardware-requirements/#background-on-memory","title":"Background on memory","text":"

For experimentation, we used multiple Shadowserver Poodle reports for demonstration purpose, totaling in 120 MB of data. All numbers are estimates and are rounded. In memory, the report data requires 160 MB. After parsing, the memory usage increases to 850 MB in total, as every data line is stored as JSON, with additional information plus the original data encoded in Base 64. The further processing steps depend on the configuration, but you can estimate that caches (for lookups and deduplication) and other added information cause an additional size increase of about 2x. Once a dataset finished processing in IntelMQ, it is no longer stored in memory. Therefore, the memory is only needed to catch high load.

The above numbers result in a factor of 14 for input data size vs. memory required by Redis. Assuming some overhead and memory for the bots' processes, a factor of 20 seems sensible.

To reduce the amount of required memory and disk size, you can optionally remove the raw data field, see this section in the FAQ.

Depending on your setup you might have to install sudo to make it possible for the intelmq-api to run the intelmq command as the user-account usually used to run intelmq (which is also often called intelmq).

intelmq-api is configured using a configuration file in json format. intelmq-api tries to load the configuration file from /etc/intelmq/api-config.json and ${PREFIX}/etc/intelmq/api-config.json, but you can override the path setting the environment variable INTELMQ_API_CONFIG. (When using Apache, you can do this by modifying the Apache configuration file shipped with intelmq-api, the file contains an example)

When running the API using hug, you can set the environment variable like this:

INTELMQ_API_CONFIG=/etc/intelmq/api-config.json hug -m intelmq_api.serve\n

The default configuration which is shipped with the packages is also listed here for reference:

On Debian based systems, the default path for the session_store is /var/lib/dbconfig-common/sqlite3/intelmq-api/intelmqapi, because the Debian package uses the Debian packaging tools to manage the database file.

The following configuration options are available:

"},{"location":"admin/configuration/intelmq-api/#permissions","title":"Permissions","text":"

intelmq-api tries to write a couple of configuration files in the ${PREFIX}/etc/intelmq directory - this is only possible if you set the permissions accordingly, given that intelmq-api runs under a different user. The user the API run as also needs write access to the folder the session_store is located in, otherwise there will be an error accessing the session data. If you\\'re using the default Apache 2 setup, you might want to set the group of the files to www-data and give it write permissions (chmod -R g+w <directoryname>). In addition to that, the intelmq-manager tries to store the bot positions via the API into the file ${PREFIX}/etc/intelmq/manager/positions.conf. You should therefore create the folder ${PREFIX}/etc/intelmq/manager and the file positions.conf in it.

Most of the cases, bots will need to be configured as continuous run mode (the default) in order to have them always running and processing events. Usually, the types of bots that will require the continuous mode will be Parsers, Experts and Outputs. To do this, set run_mode to continuous in the runtime.yaml for the bot. Check the following example:

blocklistde-apache-parser:\n  name: Blocklist.de Parser\n  group: Parser\n  module: intelmq.bots.parsers.blocklistde.parser\n  description: Blocklist.DE Parser is the bot responsible to parse the report and sanitize the information.\n  enabled: false\n  run_mode: continuous\n  parameters: ...\n

You can now start the bot using the following command:

In many cases, it is useful to schedule a bot at a specific time (i.e. via cron(1)), for example to collect information from a website every day at midnight. To do this, set run_mode to scheduled in the runtime.yaml for the bot. Check out the following example:

blocklistde-apache-collector:\n  name: Generic URL Fetcher\n  group: Collector\n  module: intelmq.bots.collectors.http.collector_http\n  description: All IP addresses which have been reported within the last 48 hours as having run attacks on the service Apache, Apache-DDOS, RFI-Attacks.\n  enabled: false\n  run_mode: scheduled\n  parameters:\n    feed: Blocklist.de Apache\n    provider: Blocklist.de\n    http_url: https://lists.blocklist.de/lists/apache.txt\n    ssl_client_certificate: null\n

You can schedule the bot with a crontab-entry like this:

0 0 * * * intelmqctl start blocklistde-apache-collector\n

Bots configured as scheduled will exit after the first successful run. Setting enabled to false will cause the bot to not start with intelmqctl start, but only with an explicit start, in this example intelmqctl start blocklistde-apache-collector.

"},{"location":"admin/configuration/intelmq/#additional-runtime-parameters","title":"Additional Runtime Parameters","text":"

Some of the parameters are deliberately skipped from the User Guide because they are configured via graphical user interface provided by the IntelMQ Manager. These parameters have to do with configuring the pipeline: defining how the data is exchanged between the bots. Using the IntelMQ Manager for this have many benefits as it guarantees that the configuration is correct upon saving.

However as an administrator you should be also familiar with the manual (and somewhat tedious) configuration. For each bot there are two parameters that need to be set:

source_queue

(optional, string) The name of the source queue from which the bot is going to processing data. Each bot has maximum one source queue (collector bots don't have any source queue as they fetch data from elsewhere). Defaults to the bot id appended with the string -queue.

Example: a bot with id example-bot will have a default source queue named example-bot-queue.

destination_queues

(optional, object) Bots can have multiple destination queues. Destination queues can also be grouped into named paths. There are two special path names _default and _on_error. The path _default is used if the path is not is specified by the bot itself (which is the most common case). In case of an error during the processing, the message will be sent to the _on_error path if specified (optional).

Only few of the bots (mostly expert bots with filtering capabilities) can take advantage of arbitrarily named paths. Some expert bots are capable of sending messages to paths, this feature is explained in their documentation, e.g. the Filter expert and the Sieve expert.

Example:

blocklistde-apache-collector:\n  # ...\n  parameters:\n    # ...\n    destination_queues:\n      _default:\n        - <first destination pipeline name>\n        - <second destination pipeline name>\n      _on_error:\n        - <optional first destination pipeline name in case of errors>\n        - <optional second destination pipeline name in case of errors>\n      other-path:\n        - <second destination pipeline name>\n        - <third destination pipeline name>\n

"},{"location":"admin/database/elasticsearch/#configuration-without-logstash","title":"Configuration without Logstash","text":"

This case involves two steps:

  1. Configure IntelMQ to output data directly into Elasticsearch.

  2. Configure Elasticsearch for ingesting the inserted data.

Bug

This section of the documentation is currently incomplete and will be updated later.

"},{"location":"admin/database/elasticsearch/#configuration-with-logstash","title":"Configuration with Logstash","text":"

This case involves three steps:

  1. Configuring IntelMQ to output data to Redis.

  2. Configure Logstash to collect data from Redis and insert them into Elasticsearch.

  3. Configure Elasticsearch for ingesting the inserted data.

Each step is described in detail in the following sections.

"},{"location":"admin/database/elasticsearch/#configuring-intelmq","title":"Configuring IntelMQ","text":"

In order to pass IntelMQ events to Logstash we will utilize already installed Redis. Add a new Redis Output Bot to your pipeline. As the minimum fill in the following parameters: bot-id, redis_server_ip (can be hostname) , redis_server_port, redis_password (if required, else set to empty!), redis_queue (name for the queue). It is recommended to use a different redis_db parameter than used by the IntelMQ (specified as source_pipeline_db , destination_pipeline_db and statistics_database).

Example values:

bot-id: redis-output\nredis_server_ip: 10.10.10.10\nredis_server_port: 6379\nredis_db: 4\nredis_queue: logstash-queue\n

Warning

You will not be able to monitor this redis queue via IntelMQ Manager.

"},{"location":"admin/database/elasticsearch/#configuring-logstash","title":"Configuring Logstash","text":"

Logstash defines pipelines as well. In the pipeline configuration of Logstash you need to specify where it should look for IntelMQ events, what to do with them and where to pass them.

"},{"location":"admin/database/elasticsearch/#input","title":"Input","text":"

This part describes how to receive data from Redis queue. See the example configuration and comments below:

input {\n  redis {\n    host => \"10.10.10.10\"\n    port => 6379\n    db => 4 \n    data_type => \"list\"\n    key => \"logstash-queue\"\n  }\n}\n

Tip

You can use environment variables for the Logstash configuration, for example host => \"${REDIS_HOST:10.10.10.10}\". The value will be taken from the environment variable $REDIS_HOST. If the environment variable is not set then the default value of 10.10.10.10 will be used instead.

"},{"location":"admin/database/elasticsearch/#filter-optional","title":"Filter (optional)","text":"

Before passing the data to the database you can apply certain changes. This is done with filters. See an example:

filter {\n  mutate {\n    lowercase => [\"source.geolocation.city\", \"classification.identifier\"]\n    remove_field => [\"__type\", \"@version\"]\n  }\n  date {\n    match => [\"time.observation\", \"ISO8601\"]\n  }\n}\n

Tip

It is recommended to use the date filter: generally we have two timestamp fields - time.source (provided by the feed source this can be understood as when the event happened; however it is not always present) and time.observation (when IntelMQ collected this event). Logstash also adds another field @timestamp with time of processing by Logstash. While it can be useful for debugging, I recommend to set the @timestamp to the same value as time.observation.

Warning

It is not recommended to apply any modifications to the data (within the mutate key) outside of the IntelMQ. All necessary modifications should be done only by appropriate IntelMQ bots. This example only demonstrates the possibility.

"},{"location":"admin/database/elasticsearch/#output","title":"Output","text":"

The pipeline also needs output, where we define our database (Elasticsearch). The simplest way of doing so is defining an output like this:

output {\n  elasticsearch {\n    hosts => [\"http://10.10.10.11:9200\", \"http://10.10.10.12:9200\"]\n    index => \"intelmq-%{+YYYY.MM}\"\n  }\n}\n

Tip

Authors experience, hardware equipment and the amount of events collected led to having a separate index for each month. This might not necessarily suit your needs, but it is a suggested option.

Warning

By default the ELK stack uses insecure HTTP. It is possible to setup Security for secure connections and basic user management. This is possible with the Basic (free) licence since versions 6.8.0 and 7.1.0.

"},{"location":"admin/database/elasticsearch/#configuring-elasticsearch","title":"Configuring Elasticsearch","text":"

Configuring Elasticsearch is entirely up to you and should be consulted with the official documentation. What you will most likely need is something called index template mappings. IntelMQ provides a tool for generating such mappings. See ElasticMapper Tool.

Danger

Default installation of Elasticsearch database allows anyone with cURL and connection capability to have administrative access to the database. Make sure you secure your toys!

Timescale DB is a PostgreSQL extension to add time-series support, which is quite handy as you don't have to learn other syntaxes as you already know. You can use the SQL Queries as before, the extension will handle the rest. To see all limitations, please check the Timescale DB Documentation.

"},{"location":"admin/database/postgresql/#what-is-time-series","title":"What is time-series?","text":"

Time-series has been invented as traditional database design like relational or nosql are not made for time-based data. A big benefit of time-series instead of other database designs over a time-based search pattern is the performance. As IntelMQ uses data based upon time, this design is awesome & will give you a performance boost.

"},{"location":"admin/database/postgresql/#how-to-choose-the-time-column","title":"How to choose the time column?","text":"

To utilize the time-series, choose a column containing the right time. This is then used by you for manual queries and graphs, and also by the database itself for organizing the data.

An Event has two fields that can be used for this: time.source or time.observation. Depending on your needs (tracking when the event occurred or when it was detected, if different), choose one of them.

You can use the :ref:intelmq_psql_initdb tool to generate SQL schema valid for TimescaleDB by passing the partitioning key:

intelmq_psql_initdb --partition-key \"time.source\"\n
"},{"location":"admin/database/postgresql/#how-to-setup","title":"How to setup","text":"

Thanks to TimescaleDB its very easy to setup.

  1. Choose your preferred Timescale DB environment & follow the installation instructions. 2. Now lets create a hypertable, which is the timescale DB time-series structure. SELECT create_hypertable('', 'time.source');. 3. Now our hypertable is setup & timescaleDB takes care of the rest. You can perform queries as usual, for further information please check Timescale DB Documentation.

To update your existing database to use this awesome time-series feature, just follow the How to setup instruction. You can perform the hypertable command even on already existing databases. BUT there are some limitations from timescaleDB.

"},{"location":"admin/database/postgresql/#separating-raw-values-in-postgresql-using-view-and-trigger","title":"Separating raw values in PostgreSQL using view and trigger","text":"

In order to reduce the row size in the events table, the raw column's data can be separated from the other columns. While the raw-data is about 30-50% of the data row's size, it is not used in most database queries, as it serves only a backup functionality. Other possibilities to reduce or getting rid of this field are described in the FAQ, section faq-remove-raw-data.

The steps described here are best performed before the events table is filled with data, but can as well be done with existing data.

The approach requires four steps:

  1. An existing events table, see the first section of this document.
  2. Deleting or renaming the raw column of the events table.
  3. Creating a table raws which holds only the raw field of the events and linking both tables using the event_id.
  4. Creating the view v_events which joins the tables events and raws.
  5. Creating the function process_v_events_insert and INSERT trigger tr_events.

The last steps brings us several advantages:

The complete SQL script can be generated using the intelmq_psql_initdb. It does not cover step 2 to avoid accidental data loss - you need to do this step manually.

"},{"location":"admin/database/postgresql/#other-docs","title":"Other docs","text":"

You have two basic choices to run PostgreSQL:

  1. on the same machine as intelmq, then you could use Unix sockets if available on your platform
  2. on a different machine. In which case you would need to use a TCP connection and make sure you give the right connection parameters to each psql or client call.

Make sure to consult your PostgreSQL documentation about how to allow network connections and authentication in case 2.

PostgreSQL Version

Any supported version of PostgreSQL should work (v>=9.2 as of Oct 2016) [1].

If you use PostgreSQL server v >= 9.4, it gives you the possibility to use the time-zone formatting string \"OF\" for date-times and the GiST index for the CIDR type. This may be useful depending on how you plan to use the events that this bot writes into the database.

How to install

Use intelmq_psql_initdb to create initial SQL statements from harmonization.conf. The script will create the required table layout and save it as /tmp/initdb.sql

You need a PostgreSQL database-user to own the result database. The recommendation is to use the name intelmq . There may already be such a user for the PostgreSQL database-cluster to be used by other bots. (For example from setting up the expert/certbund_contact bot.)

Therefore if still necessary: create the database-user as postgresql superuser, which usually is done via the system user postgres:

createuser --no-superuser --no-createrole --no-createdb --encrypted --pwprompt intelmq\n

Create the new database:

createdb --encoding='utf-8' --owner=intelmq intelmq-events\n

(The encoding parameter should ensure the right encoding on platform where this is not the default.)

Now initialize it as database-user intelmq (in this example a network connection to localhost is used, so you would get to test if the user intelmq can authenticate):

psql -h localhost intelmq-events intelmq </tmp/initdb.sql\n

PostgreSQL and null characters

While null characters (0, not SQL \"NULL\") in TEXT and JSON/JSONB fields are valid, data containing null characters can cause troubles in some combinations of clients, servers and each settings. To prevent unhandled errors and data which can't be inserted into the database, all null characters are escaped (u0000) before insertion.

"},{"location":"admin/database/splunk/","title":"Splunk","text":""},{"location":"admin/database/splunk/#sending-intelmq-events-to-splunk","title":"Sending IntelMQ events to Splunk","text":"
  1. Go to Splunk and configure in order to be able to receive logs (intelmq events) to a TCP port
  2. Use TCP output bot and configure accordingly to the Splunk configuration that you applied.
"},{"location":"admin/database/sqlite/","title":"SQLite","text":""},{"location":"admin/database/sqlite/#sqlite","title":"SQLite","text":"

Similarly to PostgreSQL, you can use intelmq_psql_initdb to create initial SQL statements from harmonization.conf. The script will create the required table layout and save it as /tmp/initdb.sql.

Create the new database (you can ignore all errors since SQLite doesn't know all SQL features generated for PostgreSQL):

sqlite3 your-db.db\nsqlite> .read /tmp/initdb.sql\n

Then, set the database parameter to the your-db.db file path.

To output data to SQLite use SQL Output Bot with parameter engine set to sqlite. For more information see SQL Output Bot documentation page.

While MISP and IntelMQ seem to solve similar problems in the first hindsight, their intentions and strengths differ significantly.

In a nutshell, MISP stores manually curated indicators (called attributes) grouped in events. An event can have an arbitrary number of attributes. MISP correlates these indicators with each other and can synchronize the data between multiple MISP instances.

On the other side, IntelMQ in it's essence (not considering the EventDB <eventdb>) has no state or database, but is stream-oriented. IntelMQ acts as a toolbox which can be configured as needed to automate processes of mass data with little or no human interaction At the end of the processing the data may land in some database or be sent to other systems.

Both systems do not intend to replace each other or do compete. They integrate seamless and combine each other enabling more use-cases and

"},{"location":"admin/integrations/n6/#data-format","title":"Data format","text":"

The internal data representation differs between IntelMQ and n6, so any data exchange between the systems requires a format conversion. For example, in n6 one message can contain multiple IP addresses, but IntelMQ is intentionally restricted to one IP address per message. Therefore, one n6 event results in one or more IntelMQ events. Because of this, and some other naming differences and ambiguities, the format conversion is not bidirectional.

In IntelMQ, the botnet is the set of all currently configured and enabled bots. All configured bots have their configuration in runtime.yaml. By default, all bots are enabled.

If no bot id is given, the command applies to all bots / the botnet. All commands except the start action are applied to all bots. But only enabled bots are started.

In the examples below, a very minimal botnet is used.

"},{"location":"admin/management/intelmq/#start","title":"start","text":"

The start action applies to all bots which are enabled.

> intelmqctl start\nStarting abusech-domain-parser...\nabusech-domain-parser is running.\nStarting abusech-feodo-domains-collector...\nabusech-feodo-domains-collector is running.\nStarting deduplicator-expert...\ndeduplicator-expert is running.\nfile-output is disabled.\nBotnet is running.\n

As we can file-output is disabled and thus has not been started. You can always explicitly start disabled bots.

The stop action applies to all bots. Assume that all bots have been running:

> intelmqctl stop\nStopping Botnet...\nStopping abusech-domain-parser...\nabusech-domain-parser is stopped.\nStopping abusech-feodo-domains-collector...\nabusech-feodo-domains-collector is stopped.\nStopping deduplicator-expert...\ndeduplicator-expert is stopped.\nStopping file-output...\nfile-output is stopped.\nBotnet is stopped.\n
"},{"location":"admin/management/intelmq/#status","title":"status","text":"

With this command we can see the status of all configured bots. Here, the botnet was started beforehand:

And if the disabled bot has also been started:

> intelmqctl status\nabusech-domain-parser is running.\nabusech-feodo-domains-collector is running.\ndeduplicator-expert is running.\nfile-output is running.\n

If the botnet is stopped, the output looks like this:

This command is used for debugging purposes.

If launched with no arguments, the bot will call its init method and start processing messages as usual -- but you see everything happens.

To send directly to the bot's output queue, just as it was sent by self.send_message() in bot's process() method, use the send argument. In our case of file-output, it has no destination queue so that nothing happens.

> intelmqctl run file-output message send '{\"time.observation\": \"2017-05-17T22:00:33+00:00\", \"time.source\": \"2017-05-17T22:00:32+00:00\"}'\nfile-output: Bot has no destination queues.\n

If run with --dryrun|-d flag, the message gets never really popped out from the source or internal pipeline, nor sent to the output pipeline. Plus, you receive a note about the exact moment the message would get sent, or acknowledged. If the message would be sent to a non-default path, the name of this path is printed on the console.

> intelmqctl run file-output process -d\nfile-output:  * Dryrun only, no message will be really sent through.\n...\nfile-output: DRYRUN: Message would be acknowledged now!\n

You may trick the bot to process a JSON instead of the Message in its pipeline with --msg|-m flag.

The intelmqctl check tool can search for orphaned queues. \"Orphaned queues\" are queues that have been used in the past and are no longer in use. For example you had a bot which you removed or renamed afterwards, but there were still messages in it's source queue. The source queue won't be renamed automatically and is now disconnected. As this queue is no longer configured, it won't show up in the list of IntelMQ's queues too. In case you are using redis as message broker, you can use the redis-cli tool to examine or remove these queues:

redis-cli -n 2\nkeys * # lists all existing non-empty queues\nllen [queue-name] # shows the length of the queue [queue-name]\nlindex [queue-name] [index] # show the [index]'s message of the queue [queue-name]\ndel [queue-name] # remove the queue [queue-name]\n

When bots are failing due to bad input data or programming errors, they can dump the problematic message to a file along with a traceback, if configured accordingly. These dumps are saved at in the logging directory as [botid].dump as JSON files. IntelMQ comes with an inspection and reinjection tool, called intelmqdump. It is an interactive tool to show all dumped files and the number of dumps per file. Choose a file by bot-id or listed numeric id. You can then choose to delete single entries from the file with e 1,3,4, show a message in more readable format with s 1 (prints the raw-message, can be long!), recover some messages and put them back in the pipeline for the bot by a or r 0,4,5.

Bots and the intelmqdump tool use file locks to prevent writing to already opened files. Bots are trying to lock the file for up to 60 seconds if the dump file is locked already by another process (intelmqdump) and then give up. Intelmqdump does not wait and instead only shows an error message.

By default, the show command truncates the raw field of messages at 1000 characters to change this limit or disable truncating at all (value 0), use the --truncate parameter.

Assuming you want to create a bot for a new 'Abuse.ch' feed. It turns out that here it is necessary to create different parsers for the respective kind of events (e.g. malicious URLs). Therefore, the usual hierarchy intelmq/bots/parser/<FEED>/parser.py would not be suitable because it is necessary to have more parsers for each Abuse.ch Feed. The solution is to use the same hierarchy with an additional \"description\" in the file name, separated by underscore. Also see the section Directories and Files naming.

Example (including the current ones):

/intelmq/bots/parser/abusech/parser_domain.py\n/intelmq/bots/parser/abusech/parser_ip.py\n/intelmq/bots/parser/abusech/parser_ransomware.py\n/intelmq/bots/parser/abusech/parser_malicious_url.py\n

"},{"location":"dev/bot-development/#logging","title":"Logging","text":""},{"location":"dev/bot-development/#log-messages-format","title":"Log Messages Format","text":"

Log messages have to be clear and well formatted. The format is the following:

Format:

<timestamp> - <bot id> - <log level> - <log message>\n

Rules:

When the logger instance is created, the bot id must be given as parameter anyway. The function call defines the log level, see below.

The Bot class creates a logger with that should be used by bots. Other components won't log anyway currently. Examples:

self.logger.info('Bot start processing.')\nself.logger.error('Pipeline failed.')\nself.logger.exception('Pipeline failed.')\n

The exception method automatically appends an exception traceback. The logger instance writes by default to the file /opt/intelmq/var/log/[bot-id].log and to stderr.

Parameters for string formatting are better passed as argument to the log function, see https://docs.python.org/3/library/logging.html#logging.Logger.debug In case of formatting problems, the error messages will be better. For example:

self.logger.debug('Connecting to %r.', host)\n
"},{"location":"dev/bot-development/#error-handling","title":"Error handling","text":"

The bot class itself has error handling implemented. The bot itself is allowed to throw exceptions and intended to fail! The bot should fail in case of malicious messages, and in case of unavailable but necessary resources. The bot class handles the exception and will restart until the maximum number of tries is reached and fail then. Additionally, the message in question is dumped to the file /opt/intelmq/var/log/[bot-id].dump and removed from the queue.

"},{"location":"dev/bot-development/#initialization","title":"Initialization","text":"

Maybe it is necessary so setup a Cache instance or load a file into memory. Use the init function for this purpose:

You can always start any bot directly from command line by calling the executable. The executable will be created during installation a directory for binaries. After adding new bots to the code, install IntelMQ to get the files created. Don't forget to give an bot id as first argument. Also, running bots with other users than intelmq will raise permission errors.

$ sudo -i intelmq\n$ intelmqctl run file-output  # if configured\n$ intelmq.bots.outputs.file.output file-output\n

You will get all logging outputs directly on stderr as well as in the log file.

"},{"location":"dev/bot-development/#examples","title":"Examples","text":""},{"location":"dev/bot-development/#parsers","title":"Parsers","text":"

Parsers can use a different, specialized Bot-class. It allows to work on individual elements of a report, splitting the functionality of the parser into multiple functions:

For common cases, like CSV, existing function can be used, reducing the amount of code to implement. In the best case, only parse_line needs to be coded, as only this part interprets the data.

You can have a look at the implementation intelmq/lib/bot.py or at examples, e.g. the DummyBot in intelmq/tests/lib/test_parser_bot.py. This is a stub for creating a new Parser, showing the parameters and possible code:

class MyParserBot(ParserBot):\n\n    def parse(self, report):\n        \"\"\"A generator yielding the single elements of the data.\n\n        Comments, headers etc. can be processed here.

"},{"location":"dev/bot-development/#parse_line","title":"parse_line","text":"

One line can lead to multiple events, thus parse_line can't just return one Event. Thus, this function is a generator, which allows to easily return multiple values. Use yield event for valid Events and return in case of a void result (not parsable line, invalid data etc.).

"},{"location":"dev/bot-development/#tests","title":"Tests","text":"

In order to do automated tests on the bot, it is necessary to write tests including sample data. Have a look at some existing tests:

Ideally an example contains not only the ideal case which should succeed, but also a case where should fail instead. (TODO: Implement assertEventNotEqual or assertEventNotcontainsSubset or similar) Most existing bots are only tested with one message. For newly written test it is appreciable to have tests including more then one message, e.g. a parser fed with an report consisting of multiple events.

import unittest\n\nimport intelmq.lib.test as test\nfrom intelmq.bots.parsers.exampleparser.parser import ExampleParserBot  # adjust bot class name and module\n\n\nclass TestExampleParserBot(test.BotTestCase, unittest.TestCase):  # adjust test class name\n    \"\"\"A TestCase for ExampleParserBot.\"\"\"\n\n    @classmethod\n    def set_bot(cls):\n        cls.bot_reference = ExampleParserBot  # adjust bot class name\n        cls.default_input_message = EXAMPLE_EVENT  # adjust source of the example event (dict), by default an empty event or report (depending on bot type)\n\n    # This is an example how to test the log output\n    def test_log_test_line(self):\n        \"\"\"Test if bot does log example message.\"\"\"\n        self.run_bot()\n        self.assertRegexpMatches(self.loglines_buffer,\n                                 \"INFO - Lorem ipsum dolor sit amet\")\n\n    def test_event(self):\n        \"\"\"Test if correct Event has been produced.\"\"\"\n        self.run_bot()\n        self.assertMessageEqual(0, EXAMPLE_REPORT)\n\n\nif __name__ == '__main__':  # pragma: no cover\n    unittest.main()\n

When calling the file directly, only the tests in this file for the bot will be expected. Some default tests are always executed (via the test.BotTestCase class), such as pipeline and message checks, logging, bot naming or empty message handling.

See the testing section about how to run the tests.

Bots can use a Redis database as cache instance. Use the intelmq.lib.utils.Cache class to set this up and/or look at existing bots, like the cymru_whois expert how the cache can be used. Bots must set a TTL for all keys that are cached to avoid caches growing endless over time. Bots must use the Redis databases >= 10, but not those already used by other bots. Look at find intelmq -type f -name '*.py' -exec grep -r 'redis_cache_db' {} + to see which databases are already used.

Expert bots and output bots handle only Events.

All Messages (Reports and Events) are Python dictionaries (or JSONs). The key names and according types are defined by the IntelMQ Data Format.

For development purposes, you need two directories:

The default root directory of the IntelMQ installation is /opt/intelmq. This directory is used for configurations (/opt/intelmq/etc), local states (/opt/intelmq/var/lib) and logs (/opt/intelmq/var/log). If you want to change it, please set the INTELMQ_ROOT_DIR environment variable with a desired location.

For repository directory, you can use any path that is accessible by users you use to run IntelMQ. For globally installed IntelMQ, the directory has to be readable by other unprivileged users (e.g. home directories on Fedora can't be read by other users by default).

To keep commands in the guide universal, we will use environmental variables for repository and installation paths. You can set them with following commands:

# Adjust paths if you want to use non-standard directories\nexport INTELMQ_REPO=/opt/dev_intelmq\nexport INTELMQ_ROOT_DIR=/opt/intelmq\n

Building your own extensions gives you a lot of freedom, but it's important to know that if your bot's entry point uses the same name as another bot, it may not be possible to use it, or to determine which one is being used.

For example, if I create a collector bot for feed source Special and run it on behalf of the organization Awesome, the suggested entry point might be intelmq.bots.collectors.awesome.special. Note that the structure of your package doesn't matter, as long as it can be imported properly.

For example, I could create a package called awesome-bots with the following file structure

   awesome_bots\n   \u251c\u2500\u2500 pyproject.toml\n   \u2514\u2500\u2500 awesome_bots\n        \u251c\u2500\u2500 __init__.py\n        \u2514\u2500\u2500 special.py\n

Most important: KEEP IT SIMPLE! This can not be over-estimated. Feature creep can destroy any good software project. But if new folks can not understand what you wrote in 10-15 minutes, it is not good. It's not about the performance, etc. It's about readability.

In general, we follow PEP8. We recommend reading it before committing code.

There are some exceptions: sometimes it does not make sense to check for every PEP8 error (such as whitespace indentation when you want to make a dict=() assignment look pretty. Therefore, we do have some exceptions defined in the setup.cfg file.

We assume here, that origin is your own fork. We first add the upstream repository:

 git remote add upstream https://github.com/certtools/intelmq.git\n

Syncing develop:

 git checkout develop\n git pull upstream develop\n git push origin develop\n

You can do the same with the branches master and maintenance.

Create a separate feature-branch to work on, sync develop with upstream. Create working branch from develop:

 git checkout develop\n git checkout -b bugfix\n# your work\n git commit\n

Or, for bugfixes create a separate bugfix-branch to work on, sync maintenance with upstream. Create working branch from maintenance:

git checkout maintenance\ngit checkout -b new-feature\n# your work\ngit commit\n

Getting upstream's changes for master or any other branch:

git checkout develop\ngit pull upstream develop\ngit push origin develop\n

There are 2 possibilities to get upstream's commits into your branch. Rebasing and Merging. Using rebasing, your history is rewritten, putting your changes on top of all other commits. You can use this if your changes are not published yet (or only in your fork).

git checkout bugfix\ngit rebase develop\n

Using the -i flag for rebase enables interactive rebasing. You can then remove, reorder and squash commits, rewrite commit messages, beginning with the given branch, e.g. develop.

Or using merging. This doesn't break the history. It's considered more , but also pollutes the history with merge commits.

git checkout bugfix\ngit merge develop\n

You can then create a PR with your branch bugfix to our upstream repository, using GitHub's web interface.

This guide is for developers of IntelMQ. It explains the code architecture, coding guidelines as well as ways you can contribute code or documentation. If you have not done so, please read the User Guide and the Administrator Guide first. Once you feel comfortable running IntelMQ with open source bots and you feel adventurous enough to contribute to the project, this guide is for you. It does not matter if you are an experienced Python programmer or just a beginner. There is a lot of examples to help you out.

First, import the Python module and a helper. More about the BotLibSettings later.

from intelmq.lib.bot import BotLibSettings\nfrom intelmq.bots.experts.domain_suffix.expert import DomainSuffixExpertBot\n

Then we need to initialize the bot's instance. We pass two parameters:

domain_suffix = DomainSuffixExpertBot('domain-suffix',  # bot id\nsettings=BotLibSettings | {\n'field': 'fqdn',\n'suffix_file': '/usr/share/publicsuffix/public_suffix_list.dat'}\n

As the bot is not fully initialized, we can process messages now. Inserting a message as dictionary: 

queues = domain_suffix.process_message({'source.fqdn': 'www.example.com'})\n

The return value is a dictionary of queues, e.g. the output queue and the error queue. More details below.

The methods accepts multiple messages as positional argument:

domain_suffix.process_message(\n    {'source.fqdn': 'www.example.com'},\n    {'source.fqdn': 'www.example.net'}\n)\ndomain_suffix.process_message(*[\n    {'source.fqdn': 'www.example.com'},\n    {'source.fqdn': 'www.example.net'}\n])\n

The \\\"botnet\\\" represents all currently configured bots which are explicitly enabled. It is, in essence, the graph of the bots which are connected together via their input source queues and destination queues.

To get an overview which bots are running, use intelmqctl status or use the IntelMQ Manager. Set \"enabled\": true in the runtime configuration to add a bot to the botnet. By default, bots will be configured as \"enabled\": true. See bots{.interpreted-text role=\"doc\"} for more details on configuration.

Disabled bots can still be started explicitly using intelmqctl start <bot_id>, but will remain in the state disabled if stopped (and not be implicitly enabled by the start command). They are not started by intelmqctl start in analogy to the behavior of widely used initialization systems.

Task: create a setup where each bot MAY run in a docker container

Background: It might make sense to be able to run each bot in a docker container since it fits with a lot of new paradigms in orchestration. With a proper template, each bot running in a docker container could send its logs to some central logger (for example splunk or similar) and the sysadmin/devops teams which are already using these systems for monitoring alerts can properly fit the IntelMQ logs and alerts to their regular daily routine. Docker also allows the sysadmin/devops folks to centrally manage the system.

Whilst restart is a mere stop & start, performing intelmqctl reload <bot_id> will not stop the bot, permitting it to keep the state: the same common behavior as for ( Linux) daemons. It will initialize again (including reading all configuration again) after the current action is finished. Also, the rate limit/sleep is continued (with the new time) and not interrupted like with the restart command. So if you have a collector with a rate limit of 24 h, the reload does not trigger a new fetching of the source at the time of the reload, but just 24 h after the last run -- with the new configuration. Which state the bots are keeping depends on the bots of course.

IntelMQ has a modular structure consisting of bots. There are four types of bots:

Each bot has one source queue (except collectors) and can have multiple destination queues (except outputs). But multiple bots can write to the same pipeline (queue), resulting in multiple inputs for the next bot.

Every bot runs in a separate process. A bot is identifiable by a bot id.

Currently only one instance (i.e. with the same bot id) of a bot can run at the same time. Concepts for multiprocessing are being discussed, see this issue: Multiprocessing per queue is not supported #186 <186>. Currently you can run multiple processes of the same bot ( with different bot ids) in parallel.

Example: multiple gethostbyname bots (with different bot ids) may run in parallel, with the same input queue and sending to the same output queue. Note that the bot providing the input queue must have the load_balance option set to true.

The right decision whom to contact about a specific incident is vital to get the incident resolved as quick as possible. Different types of events may required different abuse-contact to be selected. For example, issues about a device, e.g. a vulnerability in the operating system or an application, is better sent to the hoster which can inform the server administrator. For website-related issues, like defacements or phishing, the domain owner (maintaining the content of the website) could be the better and more direct contact. Additionally, different CERT's have different approaches and different contact databases. Multiple information sources have different information, and some sources are more accurate than others. IntelMQ can query multiple sources of abuse-contacts and combine them. Internal databases, like a Constituency Portal provide high-quality and first-hand contact information.

Bug

This section of the documentation is currently incomplete and will be added later.

"},{"location":"user/api/#usage-from-programs","title":"Usage from programs","text":"

The IntelMQ API can also be used from programs, not just browsers. To do so, first send a POST-Request with JSON-formatted data to http://localhost/intelmq/v1/api/login/

{\n    \"username\": \"$your_username\",\n    \"password\": \"$your_password\"\n}\n

With valid credentials, the JSON-formatted response contains the login_token. This token can be used like an API key in the Authorization header for the next API calls:

Authorization: $login_token\n

Here is a full example using curl:

  1. Authentication step: 

    curl --location --request POST \"http://localhost/intelmq/v1/api/login/\" \\\n     --header \"Content-Type: application/x-www-form-urlencoded\" \\\n     --data-urlencode \"username=$username\"\\\n     --data-urlencode \"password=$password\"\n
    {\"login_token\":\"68b329da9893e34099c7d8ad5cb9c940\",\"username\":\"$username\"}\n

    curl --location \"http://localhost/intelmq/v1/api/version\" \\\n     --header \"Authorization: 68b329da9893e34099c7d8ad5cb9c940\"\n

"},{"location":"user/bots/#request-tracker","title":"Request Tracker","text":"

Request Tracker Collector fetches attachments from an RTIR instance.

This rt bot will connect to RT and inspect the given search_queue for tickets matching all criteria in search_*, Any matches will be inspected. For each match, all (RT-) attachments of the matching RT tickets are iterated over and within this loop, the first matching filename in the attachment is processed. If none of the filename matches apply, the contents of the first (RT-) \"history\" item is matched against the regular expression for the URL (url_regex).

The parameter http_timeout_max_tries is of no use in this collector.

Search

The parameters prefixed with search_ allow configuring the ticket search.

Empty strings and null as value for search parameters are ignored.

File downloads

Attachments can be optionally unzipped, remote files are downloaded with the http_* settings applied.

If url_regex or attachment_regex are empty strings, false or null, they are ignored.

Ticket processing

Optionally, the RT bot can \"take\" RT tickets (i.e. the user is assigned this ticket now) and/or the status can be changed (leave set_status empty in case you don't want to change the status). Please note however that you MUST do one of the following: either \"take\" the ticket or set the status (set_status). Otherwise, the search will find the ticket every time and get stuck in an endless loop.

In case a resource needs to be fetched and this resource is permanently not available (status code is 4xx), the ticket status will be set according to the configuration to avoid processing the ticket over and over. For temporary failures the status is not modified, instead the ticket will be skipped in this run.

Time search

To find only tickets newer than a given absolute or relative time, you can use the search_not_older_than parameter. Absolute time specification can be anything parseable by dateutil, best use a ISO format.

Relative must be in this format: [NUMBER] [TIMESPAN]s, e.g. 3 days. Timespan can be hour, day, week, month or year. Trailing 's' is supported for all timespans. Relative times are subtracted from the current time directly before the search is performed.

"},{"location":"user/bots/#shodan-stream","title":"Shodan Stream","text":"

Queries the Shodan Streaming API.

Requires the shodan library to be installed:

Module: intelmq.bots.collectors.shodan.collector_stream

Parameters (also expects feed parameters and HTTP parameters):

Only the proxy is used (requires shodan-python > 1.8.1). Certificate is always verified.

countries

() A list of countries to query for. If it is a string, it will be spit by ,.

alert

() Alert ID from monitor.shodan.io.

If the stream is interrupted, the connection will be aborted using the timeout parameter. No error will be logged if the number of consecutive connection fails does not reach the parameter error_max_retries. Instead of errors, an INFO message is logged. This is a measurement against too frequent ERROR logging messages. The consecutive connection fails are reset if a data line has been successfully transferred. If the consecutive connection fails reaches the parameter error_max_retries, an exception will be thrown and rate_limit applies, if not null.

Module: intelmq.bots.parsers.generic.parser_csv

Parameters

columns

(required, string/array of strings) A list of strings or a string of comma-separated values with field names. The names must match the IntelMQ Data Format field names. Empty column specifications and columns named __IGNORE__ are ignored. E.g.

columns:\n  - \"source.ip\"\n  - \"source.fqdn\"\n  - \"extra.http_host_header\"\n  - \"__IGNORE__\"\n

is equivalent to:

columns: \"source.ip,source.fqdn,extra.http_host_header,__IGNORE__\"\n

The fourth column is not used in this example.

It is possible to specify multiple columns using the | character. E.g.

columns:\n  - \"source.url|source.fqdn|source.ip\"\n  - \"source.fqdn\"\n  - \"extra.http_host_header\"\n  - \"__IGNORE__\"\n

First, the bot will try to parse the value as URL, if it fails, it will try to parse it as FQDN, if that fails, it will try to parse it as IP, if that fails, an error will be raised. Some use cases:

columns:\n  - \"source.url|source.fqdn|source.ip|source.network\"\n
columns:\n  - \"source.url|__IGNORE__\"\n

column_regex_search

(optional, object) A dictionary mapping field names (as given per the columns parameter) to regular expression. The field is evaluated using re.search. Eg. to get the ASN out of AS1234 use: {\"source.asn\": \"[0-9]*\"}. Make sure to properly escape any backslashes in your regular expression (see also this issue).

compose_fields

(optional, object) Compose fields from multiple columns, e.g. with data like this:

# Host,Path\nexample.com,/foo/\nexample.net,/bar/\n

Using this parameter:

compose_fields:\n  source.url: \"http://{0}{1}\"\n

You get:

http://example.com/foo/\nhttp://example.net/bar/\n

in the respective source.url fields. The value in the dictionary mapping is formatted whereas the columns are available with their index.

default_url_protocol

(optional, string) For URLs you can give a default protocol which will be prepended to the data. Defaults to null.

delimiter

(optional, string) Character used for columns separation. Defaults to , (comma).

skip_header

(optional, boolean/integer) Whether to skip the first N lines of the input (true equals to 1, false requalis to 0). Lines starting with # will be skipped additionally, make sure you do not skip more lines than needed! Defaults to false/0.

time_format

(optional, string) Allowed values: timestamp, windows_nt or epoch_millis. When null then fuzzy time parsing is used. Defaults to null.

type

(optional, string) Set the classification.type statically. Deprecated in favour of default_fields . Will be removed in IntelMQ 4.0.0.

data_type

(optional, object) Sets the data of specific type, currently only json is a supported value.

Example:

columns:\n  - source.ip\n  - source.url\n  - extra.tags\ndata_type:\n  extra.tags: json\n

It will ensure that extra.tags is treated as JSON.

filter_text

(optional, string) Only process the lines containing or not containing specified text. It is expected to be used in conjunction with filter_type.

filter_type

(optional, string) Allowed values: whitelist or blacklist. When whitelist is used, only lines containing the text specified in filter_text option will be processed. When blacklist is used, only lines NOT containing the text will be processed.

Example (processing ipset format files):

filter_text: 'ipset add '\nfilter_type: whitelist\ncolumns:\n  - __IGNORE__\n  - __IGNORE__\n  - __IGNORE__\n  - source.ip\n

type_translation

(optional, object) If the source does have a field with information for classification.type, but it does not correspond to IntelMQ's types, you can map them to the correct ones. The type_translation field can hold a dictionary, or a string with a JSON dictionary which maps the feed's values to IntelMQ's.

Example:

type_translation:\n  malware_download: \"malware-distribution\"\n

columns_required

(optional, array of booleans) An array of true/false for each column. By default, it is true for every column.

The Shadowserver parser operates on CSV formatted data.

How this bot works?

There are two possibilities for the bot to determine which report type the data belongs to in order to determine the correct mapping of the columns:

  1. Automatic report type detection

    Since IntelMQ version 2.1 the parser can detect the feed based on metadata provided by the collector.

    When processing a report, this bot takes extra.file_name from the report and looks in config.py how the report should be parsed. If this lookup is not possible, and the feedname is not given as parameter, the feed cannot be parsed.

    The field extra.file_name has the following structure: %Y-%m-%d-${report_name}[-suffix].csv where the optional suffix can be something like country-geo. For example, some possible filenames are 2019-01-01-scan_http-country-geo.csv or 2019-01-01-scan_tftp.csv. The important part is the report_name, between the date and the suffix. Since version 2.1.2 the date in the filename is optional, so filenames like scan_tftp.csv are also detected.

  2. Fixed report type

    If the method above is not possible and for upgraded instances, the report type can be set with the feedname parameter. Report type is derived from the subject of Shadowserver e-mails. A list of possible values of the feedname parameter can be found in the table below in the column \"Report Type\".

Module:

intelmq.bots.parsers.shadowserver.parser

Parameters:

feedname

(optional, string) Name of the Shadowserver report. The value for each report type can be found in the schema feed_name field.

For example using curl -s https://interchange.shadowserver.org/intelmq/v1/schema | jq .[].feed_name.

overwrite

(optional, boolean) If an existing feed.name should be overwritten.

** auto_update**

(optional, boolean) Enable automatic schema download.

Supported reports:

The report configuration is stored in a shadowserver-schema.json file downloaded from https://interchange.shadowserver.org/intelmq/v1/schema.

The parser will attempt to download a schema update on startup when the auto_update option is enabled.

Schema downloads can also be scheduled as a cron job for the intelmq user:

  02  01 *   *   *     intelmq.bots.parsers.shadowserver.parser --update-schema\n

For air-gapped systems automation will be required to download and copy the file to VAR_STATE_PATH/shadowserver-schema.json.

The parser will automatically reload the configuration when the file changes.

Schema contract

Once set in the schema, the classification.identifier, classification.taxonomy, and classification.type fields will remain static for a specific report.

The schema revision history is maintained at https://github.com/The-Shadowserver-Foundation/report_schema/.

Sample configuration

  shadowserver-parser:\n    bot_id: shadowserver-parser\n    name: Shadowserver Parser\n    enabled: true\n    group: Parser\n    groupname: parsers\n    module: intelmq.bots.parsers.shadowserver.parser\n    parameters:\n      destination_queues:\n        _default: [file-output-queue]\n      auto_update: true\n    run_mode: continuous\n
"},{"location":"user/bots/#shodan","title":"Shodan","text":"

Parses data from Shodan (search, stream etc).

The parser is by far not complete as there are a lot of fields in a big nested structure. There is a minimal mode available which only parses the important/most useful fields and also saves everything in extra.shodan keeping the original structure. When not using the minimal mode if may be useful to ignore errors as many parsing errors can happen with the incomplete mapping.

Module: intelmq.bots.parsers.shodan.parser

Parameters:

ignore_errors

(optional, boolean) Defaults to true.

minimal_mode

(optional, boolean) Defaults to false.

Default scheme

The dependency url-normalize changed it's behavior in version 1.4.0 from using http:// as default scheme to https://. Version 1.4.1 added the possibility to specify it. Thus you can only use the default_scheme parameter with a current version of this library >= 1.4.1, with 1.4.0 you will always get https:// as default scheme and for older versions < 1.4.0 http:// is used.

This does not affect URLs which already include the scheme.

"},{"location":"user/bots/#aggregate","title":"Aggregate","text":"

Aggregates events based upon given fields & timespan.

Define specific fields to filter incoming events and aggregate them. Also set the timespan you want the events to get aggregated.

The \"cleanup\" procedure, sends out the aggregated events or drops them based upon the given threshold value. It is called on every incoming message and on the bot's initialization. If you're potentially running on low traffic ( no incoming events within the given timestamp ) it is recommended to reload or restart the bot via cronjob each 30 minutes (adapt to your configured timespan). Otherwise you might loose information.

This bots uses an offline database to add the public suffix to the event, derived by a domain. See or information on the public suffix list: https://publicsuffix.org/list/. Only rules for ICANN domains are processed. The list can (and should) contain Unicode data, punycode conversion is done during reading.

Note that the public suffix is not the same as the top level domain (TLD). E.g. co.uk is a public suffix, but the TLD is uk. Privately registered suffixes (such as blogspot.co.at) which are part of the public suffix list too, are ignored.

Rule processing

A short summary how the rules are processed:

The simple ones:

com\nat\ngv.at\n

example.com leads to com, example.gv.at leads to gv.at.

Wildcards:

*.example.com\n

www.example.com leads to www.example.com.

"},{"location":"user/bots/#domain-valid","title":"Domain Valid","text":"

Checks if a domain is valid by performing multiple validity checks (see below).

If the field given in domain_field does not exist in the event, the event is dropped. If the domain contains underscores (_), the event is dropped. If the domain is not valid according to the validators library, the event is dropped. If the domain's last part (the TLD) is not in the TLD-list configured by parameter tlds_domains_list, the field is dropped. Latest TLD list: https://data.iana.org/TLD/

Module: intelmq.bots.experts.domain_valid.expert

Parameters:

domain_field

(required, string) The name of the field to be validated.

"},{"location":"user/bots/#deduplicator","title":"Deduplicator","text":"

Bot responsible for dropping duplicate events. Deduplication can be performed based on an arbitrary set of fields.

Module: intelmq.bots.experts.deduplicator.expert

Parameters (also expects cache parameters):

bypass

(optional, boolean) Whether to bypass the deduplicator or not. When set to true, messages will not be deduplicated. Defaults to false.

filter_type

(optional, string) Allowed values: blacklist or whitelist. The filter type will be used to define how Deduplicator bot will interpret the parameter filter_keys in order to decide whether an event has already been seen or not, i.e., duplicated event or a completely new event.

filter_keys

(optional, string) string with multiple keys separated by comma. Please note that time.observation key will not be considered even if defined, because the system always ignore that key.

When using a whitelist field pattern and a small number of fields (keys), it becomes more important, that these fields exist in the events themselves. If a field does not exist, but is part of the hashing/deduplication, this field will be ignored. If such events should not get deduplicated, you need to filter them out before the deduplication process, e.g. using a sieve expert. See also this discussion thread on the mailing-list.

Configuration Example

Example 1

The bot with this configuration will detect duplication only based on source.ip and destination.ip keys.

parameters:\n  redis_cache_db: 6\n  redis_cache_host: \"127.0.0.1\"\n  redis_cache_password: null\n  redis_cache_port: 6379\n  redis_cache_ttl: 86400\n  filter_type: \"whitelist\"\n  filter_keys: \"source.ip,destination.ip\"\n

Example 2

The bot with this configuration will detect duplication based on all keys, except source.ip and destination.ip keys.

parameters:\n  redis_cache_db: 6\n  redis_cache_host: \"127.0.0.1\"\n  redis_cache_password: null\n  redis_cache_port: 6379\n  redis_cache_ttl: 86400\n  filter_type: \"blacklist\"\n  filter_keys: \"source.ip,destination.ip\"\n

"},{"location":"user/bots/#filter","title":"Filter","text":"

The filter bot is capable of filtering specific events.

A simple filter for messages (drop or pass) based on a exact string comparison or regular expression.

Module: intelmq.bots.experts.filter.expert

Parameters:

Parameters for filtering with key/value attributes

filter_key

(required, string) - key from data format

filter_value

(required, string) - value for the key

If this attribute is not empty (can be true, yes or whatever), the bot uses python's re.search function to evaluate the filter with regular expressions. If this attribute is empty or evaluates to false, an exact string comparison is performed. A check on string inequality can be achieved with the usage of Paths described below.

Parameters for time based filtering

not_before

(optional, string) Events before this time will be dropped. Example: 1 week.

not_after

(optional, string) - Events after this time will be dropped.

Both parameters accept string values describing absolute or relative time:
