Vulnerability researcher, pwn and reverse enthusiast; doing some CTF on my freetime @ @RMUBYGG

[Synacktiv @Synacktiv]

For our first talk, Ambre presents her previous research about firmware images identification #SSTIC2025

[Hell Diner @DinerHell]

🔥Introducing Arion🔥
A high-performance C++ framework for emulating executable binaries.
Based on Unicorn and inspired by Qiling, Arion offers an easy-to-use interface and super low execution times making it a great ally for fuzzing or other applications.

The FastCGI library, mostly used in embedded equipment, was vulnerable for decades to an integer overflow over the IPC socket in 32-bits architecture. Check out how @ShiroPycatchown found it and exploited it for RCE!

Terminé second dans ma spécialité derrière l'indétrônable @voydstack durant cette édition de l'FCSC.

Voici deux writeups pwn écrits pour être compréhensible par des semi-débutants (enfin je l'espère).

Let's go #TeamFR 🤘
Proud to be represented by those awesome hackers @DSpiricate @voydstack !

@TheLaluka @podalirius_ 'don't want to sound mean though, I just disagree with the idea, I think it could be a good one for specific cases, but not for a generic shellcode

[Shiro @ShiroPycatchown]

@TheLaluka @podalirius_ Well, portable... You got to have the right python path, the right version for the binary, and hope for it to be there. While when you have a shell, if you want it to be persistent, well, you have a shell, so just write the commands

[Shiro @ShiroPycatchown]

@TheLaluka @podalirius_ Honestly; that still sounds longer than just adding a setresuid call on the shellcode, or maybe I did not completely understand what you meant.
