CTF Handbook 🧑‍💻

Capture the Flag (CTF) in computer security is an exercise in which participants attempt to find text strings, called "flags", which are secretly hidden in purposefully vulnerable programs or websites.

These are my notes and resources for participating in CTFs or Hack the Box. I've also included people whose work has inspired me.
