About Me

Hey! I’m Marios, a Computer Science and Engineering student at TU Delft and a cybersecurity enthusiast. When I’m not busy breaking things (ethically, of course!), I’m probably solving CTF challenges, geeking out with the CYberMouflons, or dipping my toes into the world of bug bounty hunting. Spoiler: My first three submissions were marked as duplicate. 🥲 But hey, I’m just getting started!

Why This Blog?

This blog is where I share my adventures in hacking, from CTF writeups to my journey as a beginner in bug bounty hunting. It’s a place to document my learning, celebrate small wins, and laugh at the occasional facepalm moments.
