Hey, I’m Mohammed-Amine Bouaafia (aka 0xAsta) — a security researcher who documents CTF writeups, notes, and lessons learned from live competitions, practice boxes, and side experiments.

I spend most of my time on boot2root, pwn, and web challenges. This site keeps the paths, dead ends, and fixes in one place so they’re easy to revisit and share.
