About me

Welcome to my blog!

My nickname is Sudoka, it's equivalent to sudo + ka with sudo is one of the most common commands in Linux and ka means a person in Japanese. So, Sudoka indicates a practitioner of using sudo.



I am a Penetration tester, CTF player, Bounty hunter and Security researcher.
I love to play strategic and tactical games, practice calisthenics and listen to epic music.
I want to share my knowledge and experience with everyone loving cyber security.

I really admire Andy Hug, the great Kyokushin fighter. He trained in Seidokaikan, so it's why my blog named Sudokaikan.

My certificate:
  • Offensive Security Certified Professional (OSCP)
