Workshops

Extend your knowledge

In order to train your skills before the CTF, we have arranged several workshops that will be held during the morning. These workshops will cover various topics in Cyber Security. For the current edition, you can choose between: Android hacking, ROP exploitation (memory corruption), and a suprise workshop by StudSec. The suprise workshop will be announced early October at the latest. All workshops will be held on-site. However, if you are unable to attend in person, please let us know and we can try to arrange a remote option (no promises).

Sign-ups for both the workshops as well as the CTF will open halfway through October. If you already still wish to secure a spot, please e-mail us at:

Please keep in mind that the schedule and workshops can change.
