intelmq-manager problem at login
by Mika Silander 19 Sep '23

19 Sep '23

Hi again, Hints would be welcome: I've got intelmq-manager installed, the front page opens ok but when I try to login, the developer view of the browser reports the following error after I specify the account and the password: DevTools failed to load source map: Could not load content for https://FQDN_HERE/intelmq_manager/plugins/bootstrap/bootstrap.min.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE Checking what's in /usr/share/intelmq_manager/html/plugins/bootstrap/ reveals there is no file there called bootstrap.min.css.map. The files that do exist in that directory are: bootstrap.css bootstrap.js bootstrap.min.css bootstrap.min.js My setup running on a Ubuntu 22.04 LTS / Python 3.10.12 is now: ii intelmq 3.2.2-1 all Solution for IT security teams for collecting ii intelmq-api 3.1.0~rc2-1 all FastAPI-based API for the intelmq project ii intelmq-manager 3.2.0-1 all Graphical interface to manage configurations As a side note, the intelmq-api package was upgraded from intelmq-api 3.1.0-rc1 in case this could be the culprit. Br and have a nice weekend, Mika

Trouble building deb package for intelmq-3.2.2
by Mika Silander 04 Sep '23

04 Sep '23

Hi all, Before digging any deeper I'll ask the list for advice. It's possible someone's bumped into the same error. I've upgraded from Ubuntu 20 LTS with intelmq-api 3.1.0~rc-1 intelmq-manager 3.2.0-1 intelmq 3.1.0-1 python3.8 to Ubuntu 22 LTS. Now, when trying to build intelmq-3.2.2 + a few of our own bots on this upgraded host with dpkg-buildpackage -us -us -b the build fails with: test-bot: Bot stopped. test-bot: Processed 1 messages since last logging. test-bot: Bot stopped. test-bot: Processed 1 messages since last logging. test-bot: Bot stopped. E: pybuild pybuild:369: test: plugin distutils failed with: exit code=1: python3.10 setup.py test dh_auto_test: error: pybuild --test -i python{version} -p 3.10 returned exit code 13 make: *** [debian/rules:24: build] Error 255 dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2 The host has python3-distutils 3.10.8-1~22.04 installed. Any hints on what lies behind this error? Br & thanks, Mika

IntelMQ 3.2.1 release with two important bug fixes
by Sebix 28 Aug '23

28 Aug '23

Dear IntelMQ community, Together with CERT.at we just released IntelMQ version 3.2.1 containing two important bug fixes. 1. A bug in the bot's core library: > Fixes an issue which prevented bots from stopping gracefully after reloading. > As logrotate reloads all bots regularly, this bug affects most IntelMQ installations. 2. A bug in the Reverse DNS Expert bot: > Until IntelMQ version 3.2.0, the bot incorrectly cached and re-used results for /24 networks instead of single IP addresses. > If the bot retrieved the PTR for `192.0.43.7`, it was cached for `192.0.43.0/24` and used for all IP addresses in this range, for example for `192.0.43.8`. > IntelMQ version 3.2.1 fixes this issue. > The bugfix will correctly increase the cache sizes and decrease the performance, as less (incorrect) data is re-used. Upgrading: https://intelmq.readthedocs.io/en/develop/user/upgrade.html Installation: https://intelmq.readthedocs.io/en/develop/user/installation.html The PyPI package and git tag/GitHub release are published. The new deb-/rpm-packages will hit the repositories in the next few minutes and the updated Docker image follows soon. best regards Sebastian -- Institute for Common Good Technology gemeinnütziger Kulturverein - nonprofit cultural society https://sebix.at/ ZVR 1510673578

Shift of focus, new fields in IDF needed for scanning results?
by Otmar Lendl 21 Aug '23

21 Aug '23

Folks, I've been looking at some of the data that we recently processed with our IntelMQ setup (leading to https://cert.at/de/aktuelles/2023/8/verwundbare-webserver-status-in-osterre…), and I found that we need a few changes to IntelMQ to better process these kind of feeds. What happened? Initially, our focus with IntelMQ was on botnet drones which were detected via sinkholing. That's why we have the source.*, destination.*, and malware.* parameters in the data model. A C2 communication was the main inspiration. These days, a majority of the data feeds we process are generated by scanning the Internet. That can be Shodan, that can be Shadowserver, that can be from our own local scans. This is fine and good, it gives us valuable telemetry on what's going on in our constituency. But the fields needed to store the data in a consistent way are missing in the current iteration of the IDF. I don't want to pack that into extra.* or any non-standard field, I think we should come to an agreement what those elements are and how they should be handled. Here are some of the data fields I'm missing: What did the scanning find? * vendor * product * software version Are there any problems with it? * Vulnerability identifier (CVE or other, potentially multi-valued, which is another can of worms) * Severity information (e.g. associated CVSS score) * CWE IDs (https://cwe.mitre.org/index.html) Generic tagging * I see e.g. "iot", "ics" or similar ones popping up. As a minimum I think we need "vendor", "product" and "vulnerability". What do you all think? otmar ----------- References: https://datapedia.shodan.io/ There is e.g.: os string Operating system platform string product string Name of the software that powers the service. vendor string https://www.shadowserver.org/what-we-do/network-reporting/vulnerable-http-r… info on the vendor and CVEs is stored in the tag field. -- // Otmar Lendl <lendl(a)cert.at> - T: +43 1 5056416 711 // CERT Austria - https://www.cert.at/ // CERT.at GmbH, FB-Nr. 561772k, HG Wien

IntelMQ 3.2 announcement
by L. Aaron Kaplan 20 Jul '23

20 Jul '23

IntelMQ 3.2 release announcement ================================== [TLP:WHITE, please pass this on, if appropriate] Dear everyone, We are excited to announce that today we can release 3.2.0 of the open source IntelMQ (https://github.com/certtools/intelmq) incident handling automation framework. Special thanks go to Kamil (CERT.at), Sebix, Intevation, Filip Pokorny (Gethvi) and Jason from Shadowserver (you all know who you are). Also I would like to thank the 93 contributors [1] who have been helping in many ways over the last year(s) with IntelMQ. Core members of IntelMQ are committed to continuing to develop, support and enhance IntelMQ in the long run. Especially since IntelMQ is a quite well adopted extract transform load (ETL) tool for fetching incident report feeds, processing them and sending them to the right place. It is widely used in Europe and in the whole world, in CERTs, SOCs and MSSPs. And best of it, it is open source and freely available. Again, we can not thank all the contributors enough. So, what's in release 3.2? =========================== Highlights: * The main change is that IntelMQ's code can now be used as a python module / library. That means: you can easily embed the hard work that IntelMQ parser writers did into your application. It's as simple as instantiating an IntelMQ bot in python and giving it data. Thanks go to Sebix. See also https://github.com/certtools/ieps/tree/main/007 * the IntelMQ API moved from hug to fastapi [4]. The API interface stayed the same. Thanks a lot to Kamil. * We have an updated intelmq developer version docker image. Apart from that, a few other highlights: * Shadowserver parser improvements. * New shadowserver data feeds are supported * Changes time_format parameter to use new TimeFormat class * new CIF3 output bot * intelmq.bots.outputs.smtp_batch.output: Added a bot to gathering the events and sending them by e-mails at a stroke as CSV files (PR#2253 by Edvard Rejthar) As always, you can find all the nitty gritty details in the CHANGELOG [2] file and in the NEWS file [3] What's next? ============== * BSI funded a complete re-write of webinput-csv (https://github.com/Intevation/intelmq-webinput-csv), watch for an announcement soon. * Improved and re-done documentation via mkdocs (Thanks to Filip) * The upcoming next version 3.3 will have an update for the dynamic config loading of the shadowserver parser [4]. This will always give you the most current shadowserver feeds and parsers without having to wait for an official intelmq release. If you depend a lot on shadowserver feeds, it's ok to wait for the next release, which will be following very shortly. (And a big hooray to shadowserver for their help, we know that you need this feature quickly) We plan to release 3.3 in approx 1 week. Should I update? ================== Yes! **Note well**: we still have some issues with proper Debian packages for fastapi (a dependency of the new IntelMQ API server). This means re-packaging fastapi with the help of Debian developers or using the old hug API for now (no difference from a user perspective though). The deb-package for the new fastapi-based intelmq-api is currently only available on Debian 11. We are also sorting out an issue with the package build of intelmq on Debian 12: https://github.com/certtools/intelmq/issues/2384#issuecomment-1637799252 and issues on Ubuntu related to fastapi-Versions. Packages of the previous compatible hug-based intelmq-api remain the package repositories of affected distributions. Once these issues are sorted out, the new packages will become available for installation and upgrade in the respective repositories. For installations via pip or development setups, nothing needs to be kept in mind. How to update? =============== * Upgrading: https://intelmq.readthedocs.io/en/3.2.0/user/upgrade.html * Fresh installations: https://intelmq.readthedocs.io/en/3.2.0/user/installation.html (Note that the docker installation might lag behind a bit) Need help? =========== You can contact us on the mailing lists: * intelmq-dev for developers [5] * intelmq-users for users [6] See also: https://intelmq.readthedocs.io/en/3.2.0/user/support.html Thank you and thanks to all the contributors!

Odd intelmqdump testing errors
by Mika Silander 26 May '23

26 May '23

Hi all, Running the entire unit test suite of intelmq I come across a few test failures which make me ponder whether my development environment is out of sync or outdated. Tests on intelmqdump fail in the following manner: -- FAIL: test_list_and_select_dump_from_custom_location (intelmq.tests.bin.test_intelmqdump.TestIntelMQDump) [0] ---------------------------------------------------------------------- Traceback (most recent call last): File "/opt/my_development/intelmq/intelmq/tests/bin/test_intelmqdump.py", line 165, in test_list_and_select_dump_from_custom_location self.assertIn("0: test-1 empty file", output[1]) AssertionError: '0: test-1 empty file' not found in ' 0: test-1 empty file' -- So, the assertion string looks "almost" what is expected. Can this be an old(er) python library issue or something? Currently I develop on Ubuntu 20.04.6 LTS, using python 3.8.10 and the intelmqdump sources tested are from the intelmq-github/develop branch, commit tag 0780ee5c1281da8a6defcdd8f8c4722ccdbee4e8. Br, Mika

Speed dumping events in bots
by Mika Silander 17 May '23

17 May '23

Hi again, Afaik, if handling an event fails in a bot, the default behaviour of a bot is to sleep 15 seconds and then retry processing. If the retry fails, the bot dumps the event and picks the next event from the inqueue. We have a bot where it would be desirable to change this default behaviour so that the dump is done immediately on the first failure. Is there a way to configure a single bot to behave differently from other bots as described? Or will a change in configuration affect the entire bot net? If there's no easy way configuring, I guess technically I could implement exceptions to be thrown in those situations where quick dumping is desired and then call the _dump_message(?) method. However, I would prefer to modify as few bots of the official distribution as possible. Comments, pointers to docs, sources or the like are most welcome. Br, Mika

Structural change in one feed's events output by the Shadowserver Parser bot?
by Mika Silander 05 May '23

05 May '23

Hi all, Testing with intelmq 3.1.0 and specifically its Shadowserver Parser bot. I've become used to being able to read in an event output by this bot as plain JSON with the json libraries bundled in python3, but now I came across one event sample where this fails. The feed is Accessible Traversal Utilities for NAT. The troublemaker event contained the field extra.amplification, and it was output by the bot as a dict structure like 'extra.amplification': Decimal("5.2") whereas I expected the field value to be a string "5.2" or number 5.2. Please let me know what I've missed again. A json library update? Br and have a nice weekend, Mika

RFC on IEP007: Running IntelMQ as Python Library
by Sebix 04 May '23

04 May '23

Dear community, I invite you to discuss a new (IEP - IntelMQ Enhancement Proposal) IEP007: Running IntelMQ as Python Library Have you ever wondered if you can write a Python script, call a bot's process method, pass it some data and get back the enriched/modified data? (pseudo code) bot_instance = Bot(parameters) bot_instance.process_message(input message) -> output messages Strictly speaking, it *is* actually possible with the current version, but it requires some bizarre hacks like re-defining Bot's methods and overwriting internal values. Staying on the wishlist for quite a while, we intend to implement the feature now. I started the IEP007 draft and need some input from you to maximize the benefit for all the IntelMQ community (developers): https://github.com/certtools/ieps/pull/7/files Or in a readable display: https://github.com/certtools/ieps/tree/iep-007/007 What features and interfacing options would you expect when starting the bot as a library? Do you think the `Bot.process` method should be rewritten entirely now, removing the calls receive_message/send_message and converting the method into a generator (an API-breaking change)? And if yes, should this be done in one step, or separated from this bot-as-library feature, reducing the complexity of development steps? Looking forward for your ideas Sebastian -- Institute for Common Good Technology gemeinnütziger Kulturverein - nonprofit cultural society https://sebix.at/ ZVR 1510673578

IntelMQ 3.1 release
by L. Aaron Kaplan 10 Feb '23

10 Feb '23

[TLP:WHITE, please pass this on, if appropriate] Dear everyone, it took a bit of time but I am excited to announce that today we finally pushed out release 3.1 of the open source IntelMQ (https://github.com/certtools/intelmq) incident handling automation framework. Special thanks go to Kamil, Sebix, Filip Pokorny (Gethvi) and Jason from Shadowserver (you all know who you are). Also I would like to thank the 91 (!) contributors [1] who have been helping in many ways over the last year(s) with IntelMQ. This truly is became a community effort and I am very happy that we can push this project further and maintain IntelMQ in the long run as a community project. IntelMQ is by now quite well respected as a "glue" / extract transform load (ETL) tool for fetching incident report feeds, processing them and sending them to the right place. It is widely used in Europe, in CERTs, SOCs and MSSPs. And best of it, it is open source and freely available. Again, we can not thank all the contributors enough. So, what's in release 3.1? =========================== (TL;DR: - find all things here: https://github.com/certtools/intelmq/blob/develop/NEWS.md) Highlights: * Excellent support for new Shadowserver feeds (thanks to Jason and Shadowserver). This is for sure the biggest part here. Shadowserver explicitly mentions IntelMQ for processing their feeds and will maintain the IntelMQ parsers for their feeds. * Big improvements for the dataplane.org parsers * Big shodan parser improvements Apart from that, a few other highlights: * More CI/CD tests * Tons of code clean-ups * New bots such as the url expert * Enhancements of existing bots: * SQL Output support MSSQL now, * GitHub collector, * Alienvault parser improvements, * Shodan parser improvements, * maxmind geoIP expert improvements, etc etc. * Tons of behind the scenes bugfixes! * Core changes (which you won't notice much) in the core part (pipeline class) etc etc.. We also dropped some support for old, outdated versions (python 3.6 or older Debian and old RedHat systems). This slims down the code base a bit again. As always, you can find all the nitty gritty details in the CHANGELOG [2] file and in the NEWS file [3] What's next? ============== * API: We want to move the IntelMQ-API [4] to fastapi (thanks to Kamil). Due to minor issues with packaging, this is not happening today, but this is planned for next week. So, stay tuned. IntelMQ-api and intelmq will be both numbered with the same version 3.1. * More user-feedback in the next few weeks. * Update the docker images for intelmq 3.1 * Upcoming task-specific tutorials on intelmq.org (for example how to send data to Splunk, how to automate all shadowserver feeds, etc.). Courtesy of David Ruefenacht. Should I update? ================== Yes! (but first on a DEV instance!) If you run a production instance, please update on a dev instance first and cross check. Because every IntelMQ setup is different. We try to cover a lot in our testing[5] , but we can't give a guarantee that everything is completely covered, especially if there are local changes. So, yes, please update, but tell us [6] in case something breaks in your DEV environment. (But yes! you really should update - since you might really want to have all those Shadowserver and dataplane.org updates) How to update? =============== * Upgrading: https://intelmq.readthedocs.io/en/maintenance/user/upgrade.html * Fresh installations: https://intelmq.readthedocs.io/en/maintenance/user/installation.html# (Note that the docker installation might lag behind a bit) Thank you and thanks to all the contributors!
