DefCon security on Friday warned attendees at the annual hacker conference that Dateline NBC may have sent a mole with a hidden camera to the event to capture hackers admitting to crimes. DefCon says it was tipped off by their own mole at Dateline who sent them a pic of the undercover journalist who DefCon employees identified as producer Michelle Madigan.

I like the spy/counterspy aspect of this story, and it makes me think of the line from FightClub:
“We cook your meals, we haul your trash, we connect your calls, we drive your ambulances. We guard you while you sleep.”
