Penetration tester CTF player Bug bounty hunter OSCP OSWE CRTP OSEP

V1s3r1on is my hackers name, i use that name on all kind of platforms like hackthebox, tryhackme, 247ctf and ofcourse twitch. The name comes from the television show called Game of thrones. I love that show and i keep watching it over and over. For those who watched the show well you probably know viserion (one of the dragons from khaleeshi). So that is how i came up with V1s3r1on.

My name is Melvin Boers, this is a picture of me. I love hacking, CTFs, bug bounty. I love everything about hacking and also the bleu team side, so source code analysis, malware analyse and reverse engineering. I always keep learning and evolving and i am totally fine with that. It is a choice i made when i joined the infosec field.
