Hello there, I am ckrielle 👋. I am a Greek person who does security stuff. I play CTFs for the Greek CTF teams Th3Os and ECSCTeamGreece and the international team ARESx, and I currently work as a Vulnerability Researcher at CENSUS Labs focusing on browser security research. I am also a co-founder of the technical blog i0.rs. If you wish to contact me, feel free to do so either through X, or Discord. I’ll be happy to discuss with you :).
