We are a group of hackers, sysadmins, security folks, geeks, programmers, and gamers located in and around Irvine, California and the greater Orange County / Los Angeles area. Join us at 7pm every 2nd Friday of the month for a night of hacking, learning, and fun.

Our formula is simple: less elitism, and more discussion, group effort, and shared knowledge.
Everyone is welcome at Irvine Underground.

IMPORTANT UPDATE:
