The CTF event will be challenge based, i.e. the CTF is separated into small tasks that can be solved individually. The scoreboard will be web accessible and no VPN is required. We are trying our best to give all participants a delightful experience, the covered topics are somewhere around crypto, web security, reverse engineering and forensics. Find our fancy scoreboard [ here].

We are looking forward to seeing you participate - locally or from remote. Direct your questions to somebody at our booth or on IRC.

  • no DoS/automated scans/large amounts of traffic/deleting stuff on our servers.
