⚙️ Technical Spotlight: New Session at BSides Luxembourg 2026

𝗞𝗨𝗡𝗔𝗜: 𝗢𝗣𝗘𝗡-𝗦𝗢𝗨𝗥𝗖𝗘 𝗧𝗛𝗥𝗘𝗔𝗧 𝗗𝗘𝗧𝗘𝗖𝗧𝗜𝗢𝗡 𝗢𝗡 𝗟𝗜𝗡𝗨𝗫 – Quentin JEROME

Step into a practical 40-minute talk exploring how modern threat detection is evolving on Linux systems. This session introduces Kunai, an open-source tool built with eBPF to bring deep visibility, real-time monitoring, and Sysmon-like capabilities to Linux environments—where traditional security tooling often falls short.

From architecture to real-world use cases, discover how Kunai enables incident responders and defenders to detect threats, investigate events, and enhance forensic analysis across cloud and containerized systems. A must-attend for anyone working with Linux infrastructure and looking to strengthen detection and response capabilities.

Quentin Jerome is a Rust developer at CIRCL, focused on building open-source security tools driven by real-world incident response and threat detection needs. His work centers on improving visibility and empowering the security community.

File type detection just got a memory-safe upgrade — in Rust. In this talk, Quentin Jerome shows how Magic-rs brings libmagic’s power to modern, safe code — with Python bindings, a CLI tool called wiza, and real-world compatibility.

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!

A new patched release is out for both the Rust crate and Python package of magic-rs—the memory-safe implementation of libmagic!

This fixes incorrect file identification (e.g., MS Office docs). If you use magic-rs, update now to avoid false positives:

🔗 Rust: https://crates.io/crates/pure-magic
🔗 Python: https://pypi.org/project/pure-magic-rs/

⚠️ Also, don't forget to update your command line file detection companion wiza (What is Zat?): https://crates.io/crates/wiza

Thanks to the @Rafiot for reporting this!

Just before the holidays, I ran a recorded Rust training at Luxembourg House of Cybersecurity — designed to help developers with experience in other languages get up to speed faster.

🔗 Watch the full session (broken English included!):

All training materials are open-source and available here: https://github.com/ngsoti/rust-training

Not about mastery, but about cutting through the noise and getting hands-on faster. Feedback welcome—what worked (or didn’t) for you?

Interested in an internal training? You can get in touch—this can be delivered in French or English.

I learned an incredible about from this chat I had with @adulau and @cedric about @gcve

I'm still working through all the details, but I'm starting to suspect #GCVE solved many of the problems with vulnerability data I've been complaining about for a very long time

If you do anything with vulnerabilities this one is worth a listen
