Denial, anger, bargaining, depression, acceptance – anyone who has ever played security CTFs must be very familiar with those feelings. While always thrilling, the competitions also have elements of surprise, rivalry and race. Sometimes, tasks can be solved in elegant, universal ways; at other times, you spend 20 hours writing code you would never show to your friends with a straight face. In this talk, we will share some stories of victory and defeat, talk about our thoughts on playing Capture The Flag contests and discuss some of the most amusing or technically interesting tasks of the recent months, together with their solutions.
