Call for papers is now open for hack.lu 2026 (the 20th edition!)

The purpose of the hack.lu convention is to provide an open and free playground where people can discuss the implications of new technologies in society. hack.lu is a balanced mix convention where technical and non-technical people can meet and share all kinds of information freely. The convention will be held in the Grand-Duchy of Luxembourg in October (20-23.10.2026). The most significant new discoveries about computer network attacks and defenses, open-source security solutions, and pragmatic real-world security experiences will be presented in a four-day series of informative tutorials.

We are waiting for your great proposals!

Just discovered a new RAT at #hacklu and it seems the name can confuse a lot of french-speaking persons.

RATatouille

Not sure it''s a good idea for the SEO of the RAT author. ;-)

Thanks to @ddu and the whole team for the hard work.

One year, I had a chat with the fine people @suricata during the @cert_eu conference, and they were wondering why we didn't create an open source website for all the different rules (YARA, Suricata, and many others) — a place to allow comments, reviews, bundling, and integration with @misp.

We’ve just released the first beta version of the rulezet.org service! 🎉

The platform is open and publicly available and the entire back-end is fully open source.

It’s still in beta, so feedback is very welcome!
