3rd Annual DISC 2023 Capture the Flag (CTF) Was Conquered
Summary: Dragos held its third annual DISC Capture the Flag contest on November 5, 2023, with 1,507 registered players across 866 teams working through 47 ICS/OT challenges built on a full MITRE ATT&CK for ICS kill chain. Hungary's ukatemi won for the second year in a row, completing all 47 challenges and earning all 24,600 points in 31 hours and 39 minutes, with only three teams finishing the two-day event.
Why it matters: The hardest challenge, a custom buffer overflow exercise, was solved by just 0.85% of registered teams while the easiest was solved by 85% - a spread that shows how thin the pool of practitioners is at the OT-specific end of the skill range.
