handling of time frames
by Sebastian Wagner 14 Dec '17

14 Dec '17

Dear list, in pull request #944 (netlab 360 enh [0]) by navtej an issue came up which can't be solved trivially: The feed Netlab 360 DGA[1] - which is already included in intelmq - provides a validity time frame for each domain. Most of those (~90%) end in 2030 while the start date is the current day at 00:00. So both start and end time are artificial. And the source claims the event is valid in the future, which is a very odd. And does it actually make sense to forward this kind of information? Also, we can't really handle this time information using the current harmonization. One idea would be to set time.source to time.observation if the time.source is in the future. So time.source <= time.observation does always apply. What do you think? Sebastian [0]: https://github.com/certtools/intelmq/pull/944 [1]: http://data.netlab.360.com/feeds/dga/dga.txt - attention, quite big! The domains at the beginning have a very near end date. -- // Sebastian Wagner <wagner(a)cert.at> - T: +43 1 5056416 7201 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg

Intelmq-dev newletter 201605

= Intelmq-dev-news 05-2016 Issue 5/2016 == Topics == # Summary of IHAP meeting in April # Status update Intevation # Status update CERT.at # Status update misc == May 2016 == Dear Intelmq-dev mailing list readers, this is the second issue of intelmq developer news. We hope it's useful. TL;DR and important changes ----------------------------- The syntax of intelmqcli was changed to a new format: intelmqctl {start,stop} bot_id. This breaks compatibilty with existing scripts. If you put intelmqctl into some script, please adapt it. Also please be sure to check out the latest version of the intelmq-manager in case you use it. Lots of open issues. Progress with intelmqcli (to connect postgresql to the RT ticket system). / TL;DR === How to contribute to this newsletter? === -> contact Aaron, Dustin for future input === Summary of IHAP meeting in April === In April the IHAP Meeting took place in Vienna. * A Hacksession the night before the meeting was used by Raphael and Aaron in order to bridge MISP and IntelMQ. * Connections between Abusehelper and IntelMQ are on some CERTs wish list. XMPP is a good start. Unfortunately the XMPP Bot upstream was not fit for production. === Status report Intevation === * Still working on the KontaktDB, we appreciate the discussions that started on IHAP Meeting. We received a Pull Request from Cert.at and are currently reviewing it. * We have Scripts to import Data into the KontaktDB. Nevertheless there is some work left. * Demonstrated installation from packages on Ubuntu 14.04 on IHAP-Meeting. We propose to host the **signed** packages on our public apt-repositories. * Working on a tool similar to intelmqcli, intended to process events from the eventdb. Instead of using RT they are sent by e-mail. The tool has the working title "event-processor" and can be found here (https://github.com/Intevation/event-processor) * We did not start with support for IODEF or X-ARF yet. === Status report CERT.at developments === * we moved to python3 only. Intelmq dropped python2 support (https://github.com/certtools/intelmq/commit/2cbb42f1458a7e90539a443ec5e50ee…). This does not apply yet to the certat repo (github.com/certat/intelmq), which still supports python2.7 but only for the intelmqcli tool. * New active contributor: pedro m. reis! Welcome and thanks for working so hard on the Bitsight collector (https://github.com/certtools/intelmq/pull/493) * intelmqcli tool now supports a lot of new flags: https://github.com/certat/intelmq/issues/52 This was necessary for CERT.at since we use intelmqcli via cron job to connect to the (postgresql) eventDB , pull out all of the new data and use RT (ticket system) to send stuff out. Added flags --quiet --batch. Now intelmqcli sends via cronjob. These flags now allow CERT.at to run intelmq in full auto-mode! intelmqcli is started via cron and sends out all events to all ISPs. === Requests === * Intevation searches for testers for the packages. * We'd like to have some nice graphs in the intelmq-manager: events/sec , parse-failures/sec, etc. * implementation of whitelisting of events (filter out events based on whitelists). See https://github.com/certtools/intelmq/issues/426 * A good CSS design for the web page === Community === * RIPE abuse-c contacts can be done locally. RIPE might be able to export abuse-c infos publicly (fingers crossed). * more command line options for intelmqcli (see the https://github.com/certat/intelmq repo) * Aaron gave a presentation at the ENISA workshop "CSIRTs in Europe", 11th of May. Slides will be shared on the ENISA page. ==== intelmq.org ==== The website intelmq.org is now online, but we would like to have more content and a proper design. Do you want to contribute to intelmq, but you are not a programmer? This is your chance! Current ToDos: * Create Website Content: How-Tos / Installation Instructions, Success Stories ** How-Tos / Instructions: If you are using a special feature of IntelMQ, for instance an expert bot, try to find some time to write down a short article how you managed to get it to work and why you are using it. * Website Design == Wishlist == * **we need more test-cases!!!** * a specific config logic for ASNs: do this and that (for example sett ttl = 1 month) if event is in ASN xyz. Or "ignore" if event is in ASN xyz. This should support some kind of more-specific-less-specific inheritance, similarly to Apache directory settings. The most specific setting wins. The order could be: country code -> ASN -> netblock -> ip (/32). Open questions: what's more relevant if both domains and numbers (ASN, IPs, net blocks) exist in an event? * block based processing: for example block based team cymru lookups * parallelisation: We need to revisit this topic == Important Discussions == In case you missed something, here are the headlines of some discussion we consider interesting / important. === Mailing Lists === * [Intelmq-dev] Packaging Strategy for Bots with dependencies * [Intelmq-dev] Discussion on intelmq output / transformation architecture * [Intelmq-dev] Output format to syslog/splunk (PR#503) == Communication == Chat: irc #intelmq on freenode or webchat: [[https://webchat.freenode.net/?channels=intelmq]] Follow on twitter: @intelmqorg Weekly Conference Call every Tuesday: Dial in via the known conference bridge number.

GeoIP expert crashes with invalid database
by Thomas Hungenberg 31 Jul '17

31 Jul '17

I noticed the geoip expert bot crashed on our IntelMQ instance. In the logs I found: # tail /opt/intelmq/var/log/maxmind-geoip-expert.log maxminddb.errors.InvalidDatabaseError: Error opening database file (/opt/intelmq/var/lib/bots/maxmind_geoip/GeoLite2-City.mmdb). Is this a valid MaxMind DB file? 2017-07-28 09:23:00,674 - maxmind-geoip-expert - INFO - Bot stopped. It looks like the database file was only partially downloaded with the cron-based update last night. :-/ I was able to fix this by running /usr/bin/update-geoip-data To avoid this, I think the updater should verify the downloaded database before overwriting the file. Also, it looks like the script /usr/bin/update-geoip-data simply passes on any parameters to "mv" which is probably not a good idea: # /usr/bin/update-geoip-data --help Usage: mv [OPTION]... [-T] SOURCE DEST or: mv [OPTION]... SOURCE... DIRECTORY or: mv [OPTION]... -t DIRECTORY SOURCE... Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY. - Thomas CERT-Bund Incident Response & Malware Analysis Team

Last call for version 1.0
by Sebastian Wagner 25 Jul '17

25 Jul '17

Dear community, As the number changes introduced after RC1 is very low, we do not need a RC2. If you discovered any critical bugs and did not report them yet, please raise your voice in the next days. Bugfixes for one of the four open bugs in 1.0 are still welcome: https://github.com/certtools/intelmq/issues?q=is%3Aopen+is%3Aissue+mileston… If no new issues are found the first stable version 1.0 can thus be expected at the beginning of next week.

Version 1.0.0.rc1 release
by Sebastian Wagner 05 Jul '17

05 Jul '17

Dear community, I just uploaded/released the Release candidate 1 for our first stable version 1.0.0. Depending on the amount of bugs reported / bug fixes arriving, we will have a second release candidate or none at all. The stable version 1.0 can be expected at end of July. No more features are accepted for 1.0, only bugfixes. I created a branch develop, which will become the next feature release 1.1. All currently open pull requests are now pointing to it. The master branch will have the latest stable release, and currently - until the first stable release is done - it's the release candidate branch. See also https://github.com/certtools/intelmq/blob/master/docs/Developers-Guide.md#r… and the following section Sebastian -- // Sebastian Wagner <wagner(a)cert.at> - T: +43 1 5056416 7201 // CERT Austria - https://www.cert.at/ // Eine Initiative der nic.at GmbH - https://www.nic.at/ // Firmenbuchnummer 172568b, LG Salzburg
