A name given to individuals when they are in an exchange using the Bluetooth wireless technology. Bluejacking occurs for a short time when one literally hijacks another person’s cell phone by sending it an anonymous text message using the Bluetooth ­wireless networking system. Many in the hacker community see bluejackers as merry pranksters—­placing them in the grey zone between the White Hats and the Black Hats. For example, a published story about bluejacking describes how a group of tourists were strolling through Stockholm and admiring handicrafts in a storefront window when one of their cell phones beeped and displayed an anonymous message saying, “Try the blue sweaters. They keep you warm in the winter.” Obviously, the latter event was a harmless incident of bluejacking. More serious attacks are easily conceivable, particularly when data is stolen from cell phones and used in identity theft scams.
