🇺🇸 OpenCTF

OpenCTF, a hacking contest built on the principle of inclusion with challenges for all skill levels, is returning to DEF CON this year under new management.

OpenCTF will continue to be open to all, so if you're new to CTF come talk to us and we'll help you get started or find a team, but bring your dedication if you aspire to win. Neg9, long time players and former winners, will be organizing and hosting the contest. Get ready for the next level!
