Black Hat

NSA, the intelligence agency responsible for eavesdropping on foreign conversations and digital communications, is at Black Hat to recruite hackers to crack the "hardest problems," and is willing to put up with people who don't wear crisp white shirts every day to get them.

You can't get to every target you'd like to hack through the Internet. Sometimes it's better to hover over the WiFi network or smartphone owner and just listen covertly on what's going on. If the BUZZZZ of your engine doesn't tip off your targets.
