@Hack 2026

@HACK is Canada’s top annual student CTF (Capture the Flag) cybersecurity competition, run by TECHNATION and Hexploit Alliance.

P.S. We occasionally use the term “cybersecurity hackathon” to make things clearer for newcomers, though the event is still a true CTF.

Location: Concordia University’s downtown Montréal campus, Quebec, Canada.
