Every year, CSAW's CTF draws thousands of teams from around the world.

Designed as an entry-level CTF, this competition requires players to integrate concepts, develop skills, and learn to hack as they go. 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.  

CTF is organized by members of the NYU Tandon School of Engineering OSIRIS Lab
