PACTF charges teams of 1–5 to hack, decrypt, and do whatever it takes to solve increasingly challenging security puzzles. Our mission? Make cyber-security as fun—and educational—as possible. Unlike traditional learning approaches, PACTF has students learn by having them break vulnerable systems themselves. Teams face carefully designed problems, and on successfully execution of an attack, teams can submit proof called ‘flags’ to our website for feedback, fun and points.
