WHO AM I

I'm D0pp3lgang3r, a French engineering student passionate about web app pentesting, cryptanalysis and reverse engineering. I spend most of my free time on CTFs, malware analysis and bug bounty.

— CTF

I competed with PsychoBash and IA2R Owner a team with my classmates. I played a lot of jeopardy-style CTFs with a focus on crypto, web and reverse engineering.

I share CTF writeups after competitions end, along with personal research, things like malware reversing, vulnerability research, and offensive tooling development. Think of it as a public notebook for anything security-related I find worth documenting.
