About me

Petr's daily pentest notes and cheat sheets.

My name is Petr Juhanak, I am penetration tester and trainer at Hackerlab.cz. I founded a school for starting ethical hackers HackingKurzy.cz.

As you know when you are learning something new, there is 80 percent of practice and the rest is a theory. It's great to recall what has been proven over time and that's why I created this wiki as a pentest playbook. Everything I have learned is thanks to a security community.
