Saw this event called HackTheon Sejong 2026 and figured I’d share.
It’s a free AI & cybersecurity conference on July 9–10 at the Government Sejong Convention Center. Looks like there’ll be talks, a tech expo, and a collegiate cybersecurity competition.
If you’re a student, there’s an online prelim on April 25 and offline finals in July.
Seems to be open to undergrads (including international students).
Not sure how competitive it is, but could be a fun experience if you’re into CTFs or just want to check out a conference for free.
