please note that by winning 32C3 CTF, you will be qualified to compete at the DEF CON CTF in Las Vegas, Nevada, USA in August 2016. We hope this will give you that extra little bit of motivation to solve all challenges.
The preparations are going well so far, we have a decent number of tough challenges prepared already. We're looking forward to see you in Hamburg, so if you'll be attending the congress, make sure to come by and visit us. Also, it's a good idea to join our IRC channel on hackint: #32c3ctf
Have fun and good luck!
