Area 51 Hackers Map Buried Surveillance Network

advair writes "There's a story on SecurityFocus about a pair of Area 51 'hackers' who discovered a buried network of wireless motion sensors on the public land surrounding the "operating location near Groom Lake, Nevada." Using a frequency counter and a GPS receiver, they tracked down and logged 30 - 40 of the sensors, before the FBI and Air Force raided one of them, and questioned the other. Now one of the guys has been charged with a federal crime for allegedly removing one of the devices that was protecting a base that doesn't officially exist."
