On average, a computer security Capture The Flag event takes place every two weeks. These time-limited team hacking competitions are a gold mine of interesting, unconventional, technically challenging, surprising and just plain amazing security problems and puzzles. We, members of the Dragon Sector CTF team, would like to present some of the tasks we found most fun to solve during the most recents 30 contests we took part in. The selected challenges will be related to various areas of applied security, including: exploitation, reverse engineering, cryptography, forensics, steganography, networking, web application security, etc.
Dragon Sector is one of the top CTF teams according to the CTFTime.org ranking. It finished CTF season 2013 on 3rd place. At the time of this writing, it is ranked 1st in the 2014 ranking.
