Welcome to Capture the Flag (CTF). Every year, this annual competition draws thousands of teams from around the world.

Teams tackle problems in a series of 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.

Because the challenges are designed to teach, CTF requires contestants to integrate concepts, develop skills, and learn to hack as they go. Finalists compete on-site at one of four international CSAW locations, vying for the coveted top-three places.
