Defcon had some of the evilest, trickiest challenges I've ever faced in a CTF. And it was super fun because of it.

+1 to this - the organizers was fantastic this year. Infrastructure was amazingly solid, the room environment was comfortable, and the organizers were very open with communication.


DEF CON CTF Finals were be held in the Bally's Event Center / DEF CON Contest Area, from August 5 to August 7.

Thanks to our competitors, contestants, DEF CON staff, and everyone who visited our area for another successful year.
