J-P Won My CTF

J-P Won My CTF

Jari-Pekka Ollikainen won my Capture the Flag. It was a hacking challenge, on the last day of my ethical hacking course. He was the first to break all eight challenges.

The game tested penetration testing skills. It included mapping the attack surface using port scanning and fuzzing, cracking password protected files and breaking web applications using multiple approaches.

J-P is also one of the authors of PhishSticks (video, git). Suffice to say: never connect an unknown USB device to your computer.
