DEF CON For the first time, Vegas's annual DEF CON hacking conference has an "aviation hacking village", and the US military is scouting around there for a few good hackers to find bugs that its own hackers have missed.

"We've got some great hackers on our team and we're proud of them," Dr Will Roper, assistant secretary of the Air Force for Acquisition, Technology and Logistics, told The Register. "But we may not have the best, and that's why we're here. There's a big pool of talent out there and bringing in fresh eyes could show us stuff that we've missed."
