What is 42CTF ?

A short introduction to CTF

CTF stands for Capture The Flag. It is a cybersecurity competition, where participants have to solve challenges of various categories to gain points and progress on the scoreboard. The challenges require participants to find sort of passwords called "flags" and to submit them on the platform.
