Hi cyber people,
If you didn't notice yet, we're at 39C3 with our own assembly. If you wanna have a chat about CTFs, crypto, platypuses or other random stuff, feel free to come by. And don't forget to grab some platypuses! We printed 2000 of them ...
Also, we have a challenge that should be ready soon™

See ya around!

We just released my writeup for my first CTF challenge I ever created, "Ghostbusters" for Haix-La-Chapelle 2025 CTF @Pwn_la_Chapelle .
it involves some cool techniques for exploiting Ghostscript and PDF/PostScript file type confusion.
