42-SnowCrash

This project is an introduction to information security. The goal is to find and exploit vulnerabilities throughout the different levels.

We're given a vulnerable ISO on which we need to find 14 flags. The process is simple: we connect as levelXX and we need to find a way to connect as flagXX and execute getflag or execute is as flagXX directly to move onto the next level.
