Thank you for participating!

We want to thank all teams for participating in the rwthCTF. We hope that you had as much fun as we did and that the long hours of preparation were worth it. Hopefully, there will be another rwthCTF next year. To help us improve the organisation, please give us feedback via email ( Also, have a look at this funny (but somehow frustrating) list of messages we received before and during the CTF :-)

Following are a few impressions on how a CTF looks like from the organizers perspective.
Enjoy and see you next year!

After cyber attacks like Stuxnet, 2011 has been predicted as the year of cyber war. Governments start to build their own cyber armies to protect themselves and attack the infrastructures of others...
