Another year, another great challenge from YesWeHack.

Last weekend, I took part in the LeHack 2025 event in Paris.

TLDR: It's never too late to try to solve an old challenge.

Recently I had the pleasure to give a rump during the "Drink Love Share" meet organized by TheLaluka.

Let's talk about the "MD Auth" challenge, I admit I started with this challenge thinking it would be about "Markdown".

Last night I stumbled across an XSS in a bug bounty program, this was quite fun to exploit.

What is it ?

Last year the first day of my internship I was given a computer and asked to install and secure it for two days.
