Challenges mimic real-world scenarios modeling various computer security problems. To succeed, teams must demonstrate a profound understanding of the roles and ramifications of cyber security in these situations. Topics include Pwnable, RE, Web, Crypto, and Forensics. 

The top teams to emerge from Quals will compete on-site at one of CSAW's global reigons, vying for the coveted top three places.
