We're meeting regularly to exchange knowledge and to participate in CTF competitions. If you're interested: We've prepared three challenges for you. Solve one of them to receive an invite to our Mattermost channel. The goal of these challenges is to hack the service and steal a secret flag (which is a character string). The flags have the form flag{...}. If you succeed mail the flag to hanswurst@redrocket.club to get your very own personalized premium invite link. Alternatively, everyone can directly join our discord: https://discord.gg/5YktcJZ Happy Hacking! /******************************************************************/ Chal 1 (web): We founded a startup!
