DEF CON 28 Safe Mode Capture The Flag Competition

Every year we select the best CTF teams through a tough public qualifier game online. They then compete in an even tougher, live attack/defense CTF which will crown the best team in the league.

We're planning to live-broadcast the scores and graphs during the game. Some services will also have a broadcast component, so you'll be able to follow teams as they tackle that challenge and fight among themselves.

This year the playing schedule accommodates players in multiple timezones, so it doesn't fully overlap with the conference. However, we're going to provide recaps of the game and you're welcome to join to get a pulse of how things are evolving.
