If you want to learn to use #AI #agents and #skills, my new blog post might interest you. It's about the setup I used to play @1ns0mn1h4ck.bsky.social CTF.

Obviously, this is *not* the way to go to learn #CTF skills...

Ph0wn CTF

What's particularly cool about Ph0wn CTF?

1. It's onsite. If you haven't ever been to an onsite CTF, you absolutely must.
2. It's dedicated to connected devices, so you get to interact with tons of equipment!
3. The challenges are really awesome, yes, yes.

Ce mardi 3 mars 2026, une éclipse totale de Lune se produit. Une partie de la planète aura l’occasion de voir le satellite prendre une teinte rougeâtre, ce qui amène parfois à l’appeler « Lune de sang ».

So you're advocating for no antivirus? Is that it? Hmmm.

For ph0wn registration, we see that many of you are struggling to put several items in your cart and consequently create x different registrations.

It's simple. In pretix, you need to click on "Add tickets for a different date". Then select an other "event" : CTF, social event, workshop.

Merci de pré-installer sur vos laptops: Docker, Python 3 et Java.

Cet atelier est accessible à ceux qui ne connaissent ni Radare2 ni Ghidra.
Mais il est conseillé d'avoir des bases en assembleur ou d'avoir déjà décompilé des binaires (qq soit le logiciel utilisé).
C'est un peu technique qd meme...

Ca va parler de Radare2, de Ghidra, de MCP et d'assembleur en tout genre. L'objectif est d'utiliser l'IA pour faciliter la rétro-ingénierie. L'IA ne fait pas tout (par exemple, elle ne fait pas les crêpes que je compte déguster sur place), mais elle aide ... si on sait l'utiliser.

Venez !

Setting up your laptop before the workshop:

- It helps if you have already installed Radare2: radare.org/n/radare2.html .

- If you want to isolate your own OS from the workshop, I recommend Exegol, or Docker, or a Kali VM.
