UNSW's Security Society is running K17 CTF 2026, an online jeopardy-style contest starting September 11 that mixes approachable challenges with tougher ones for experienced players. The organizers recently trimmed the event from 48 to 24 hours to keep infrastructure support manageable, so it now wraps up on September 12. Hex-Rays is sponsoring, and teams can register through the event's own site.
