Installation documentation:

Upgrade documentation:
https://intelmq.readthedocs.io/en/maintenance/user/upgrade.html

  • Upgraded syntax to Python 3.6 (mostly Format-Strings) using pyuprade (PR#2136 by Sebastian Wagner).

Core

  • intelmq.lib.upgrades:
    • Refactor upgrade functions global configuration handling removing the old-style defaults configuration (PR#2058 by Sebastian Wagner).
    • Pass version history as parameter to upgrade functions (PR#2058 by Sebastian Wagner).
  • intelmq.lib.message:
    • Fix and pre-compile the regular expression for harmonization key names and also check keys in the extra. namespace (PR#2059 by Sebastian Wagner, fixes #1807).
  • intelmq.lib.bot.SQLBot was replaced by an SQLMixin in intelmq.lib.mixins.SQLMixin. The Generic DB Lookup Expert bot and the SQLOutput bot were updated accordingly.
    • Added support for MSSQL (PR#2171 by Karl-Johan Karlsson).
    • Added optional reconnect delay parameter (PR#2171 by Karl-Johan Karlsson).
  • Added an ExpertBot class - it should be used by all expert bots as a parent class
  • Introduced a module for IntelMQ related datatypes intelmq.lib.datatypes which for now only contains an Enum listing the four bot types
  • Added a bottype attribute to CollectorBot, ParserBot, ExpertBot, OutputBot
  • Introduces a module for IntelMQ processmanagers. The processmanagers were up until now part of the intelmqct script.
    They now reside in intelmq.lib.processmanager which also contains an interface definition the processmanager implementations must adhere to.
    Both the processmanagers and the intelmqctl script were cleaned up a bit.
    The LogLevel and ReturnType Enums were added to intelmq.lib.datatypes.
  • intelmq.lib.bot:
    • Enhance behaviour if an unconfigured bot is started (PR#2054 by Sebastian Wagner).
    • Fix line recovery and message dumping of the ParserBot (PR#2192 by Sebastian Wagner).
      • Previously the dumped message was always the last message of a report if the report contained multiple lines leading to data-loss.
    • Fix crashing at start in multithreaded bots (PR#2236 by DigitalTrustCenter).
    • Added default_fields parameter to ParserBot (PR#2293 by Filip Pokorný)
  • intelmq.lib.pipeline:
    • Changed BRPOPLPUSH to BLMOVE, because BRPOPLPUSH has been marked as deprecated by redis in favor of BLMOVE (PR#2149 and PR#2240 by Sebastian Waldbauer and Sebastian Wagner, fixes #1827, #2233).
  • intelmq.lib.utils:
    • Added wrapper resolve_dns for querying DNS, with the support for recommended methods from dnspython package in versions 1 and 2.
    • Moved line filtering inside RewindableFileHandle for easier handling and limiting number of temporary objects.
  • intelmq.lib.harmonization:
    • Fixed DateTime handling of naive time strings (previously assumed local timezone, now assumes UTC) (PR#2279 by Filip Pokorný, fixes #2278)
    • Removes tzone argument from DateTime.from_timestamp and DateTime.from_epoch_millis
    • DateTime.from_timstamp now also allows string argument
  • Removes pytz global dependency
  • Removed support for Python 3.6, including removing conditional dependencies and updating syntax to use features from newest versions. (fixes #2272)

Development

  • Removed Python 3.6 from CI.
  • Enabled tests against Python 3.11.

    • Add support for unverified SSL/STARTTLS connections (PR#2055 by Sebastian Wagner).
    • Fix exception handling for aborted IMAP connections (PR#2187 by Sebastian Wagner).
  • intelmq.bots.collectors.blueliv: Fix Blueliv collector requirements (PR#2161 by Gethvi).
  • intelmq.bots.collectors.github_api._collector_github_api: Added personal access token support (PR#2145 by Sebastian Waldbauer, fixes #1549).

  • intelmq.bots.collectors.shadowserver.collector_reports_api.py: Added file_format option to download reports in CSV format for better performance (PR#2246 by elsif2)

Parsers

  • intelmq.bots.parsers.alienvault.parser_otx: Save CVE data in extra.cve instead of extra.CVE due to the field name restriction on lower-case characters (PR#2059 by Sebastian Wagner).

  • intelmq.bots.parsers.anubisnetworks.parser: Changed field name format from extra.communication.http.x_forwarded_for_#1 to extra.communication.http.x_forwarded_for_1 due to the field name restriction on alphanumeric characters (PR#2059 by Sebastian Wagner).

  • intelmq.bots.parsers.dataplane.parser:

    • Add support for additional feeds (PR#2102 by Mikk Margus Möll).
      • DNS Recursion Desired
      • DNS Recursion Desired ANY
      • DNS Version
      • Protocol 41
      • SMTP Greet
      • SMTP Data
      • Telnet Login
      • VNC/RFB Login

  • Removed intelmq.bots.parsers.malc0de: this bot was marked as deprecated and removed from feed due to offline status (PR#2184 by Tamas Gutsohn, fixes #2178).

  • intelmq.bots.parsers.microsoft.parser_ctip:

    • Handle Payload field with non-base64-encoded JSON content and numbered dictionaries (PR#2193 by Sebastian Wagner)

  • intelmq.bots.parsers.shodan.parser (PR#2117 by Mikk Margus Möll):

    • Instead of keeping track of extra.ftp.<something>.parameters, FTP parameters are collected together into extra.ftp.features as a list of said features, reducing field count.
    • Shodan field rsync.modules is collected.
    • Conversion functions can raise NoValueException with a string argument to signify that the conversion would not succeed, such as in the case of a single IP address being given in hostnames, which would then be passed into source.reverse_dns and fail to validate as a FQDN.
    • 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.
    • _get_first_hostname to handle the first valid FQDN from a list of hostnames for hostnames in the Shodan banner, if there is one, and gives NoValueException otherwise.
    • ssl.cert.serial and ssl.dhparams.generator, which may return both integers and strings, are converted to strings.
    • Changes to method apply_mapping, such as reducing needless loop iterations, removing a big try-except, and adding the NoValueException handling described above.
    • Stops falsy values (False, 0) besides None from being filtered out.

    • Added support for Accessible AMQP, Device Identification Report (IPv4 and IPv6) (PR#2134 by Mateo Durante).

    • Removed legacy reports Amplification-DDoS-Victim, CAIDA-IP-Spoofer, Darknet, Drone, Drone-Brute-Force, IPv6-Sinkhole-HTTP-Drone, Microsoft-Sinkhole, and Sinkhole-HTTP-Drone (PR#2227 by elsif2).
    • Users storing events in a database should be aware that field names and types have been updated (PR#2227 by elsif2).
    • Corrected "Accessible-AMQP" message_length type (int) and added "STUN" support (PR#2235 by elsif2).
    • Added amplification factor to UDP scan reports (PR#2238 by elsif2).

      scan_elasticsearch:status renamed to http_code
    • Added Accessible-HTTP-proxy and Open-HTTP-proxy (PR#2246 by elsif2).
