"As the inventor of "bluesnarfing," a hack that uses Bluetooth to peek at data stored on cell phones, Laurie is dedicated to publicizing the danger of a wide-open Bluetooth connection. A bluesnarf attack can identify an unprotected phone and copy its entire address book, calendar, photos, and any other information that happens to be inside. Using a bluesnarf program, a phreak can also crash any phone within range by using Bluetooth to broadcast what Laurie calls "a corrupted message.""
