What is a CTF?

A Capture The Flag is a competition where different teams solve cyber security related challenges. Every challenge is worth a number of points depending on its difficulty. The goal of every challenge is to find the hidden flag. This CTF will feature different kinds of challenges, such as challenges related to cryptography, steganography, forensics, ... We aim to make this a beginner friendly CTF, so prior knowledge on cyber security should not be necessary. In order to get you on the right track, we also host an interactive workshop one week prior to the event, on the 10th of November. You can find more information here.


Every participant needs to be part of a team. A team can contain up to four participants. You can join an existing team or create a new team. Of course, there is no problem with participating solo, but you still have to create a team.
