Ph0wnCTF 2026 Intro

It’s been a while since the last time I update the writeups CTF. I still participate but writing all the challenge is not in my comfort zone, but CTF is not about giving up, so I will try my best to keep my pace at writing. Thanks for your visits

About This CTF

Ph0wn CTF is a French cybersecurity competition focused on signal analysis and hardware hacking.

This is a intro for their CTF, which consists of 4 really cool challenges and I managed to get 6th place. Unfortunately I couldn’t afford to go to the main event at Nice, but I really enjoyed the intro, and even got a gift from the organizer (which is a challenge from last year, so I’ll give it a try and write something about it on here).

My Ranking: 6th / ?
