Ghassen Boulares (M0rPh39s) — Tunisian CTF player, student at South Mediterranean University, FL1TZ.
I’m Ghassen Boulares, also known as M0rPh39s. I’m Tunisian, a student at South Mediterranean University, and I play CTF with FL1TZ.
This site is where the competition work gets written down properly: one challenge per post, from first look to flag, including the wrong turns. The dead ends are the useful part — every clean writeup you’ve read lies about how linear the process was.
Flags aren’t published here. The challenge files are: every writeup carries the original binaries, sources and captures, plus my solve scripts.

how I work
Ubuntu, a pwntools venv, GEF for dynamic work, and headless Ghidra through PyGhidra for decompilation. Writeups go up after the scoreboard freezes, never during a live competition.
Everything here is written for education and authorized testing — CTF infrastructure and my own lab. Don’t point it at systems you don’t own or have written permission to touch.
