Bluesnarfing

Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, often between phones, desktops, laptops, and PDAs (personal digital assistant).

[1] This allows access to calendars, contact lists, emails and text messages, and on some phones, users can copy pictures and private videos.

Access to this unique piece of data enables the attackers to divert incoming calls and messages to another device without the user's knowledge.

According to Wired magazine, this method surfaced at the Black Hat Briefings and DEF CON hacker conferences of 2004 where it was shown on the G4techTV show The Screen Savers.

[6] For example, a "rifle" with a directional antenna, Linux-powered embedded PC, and Bluetooth module mounted on a Ruger 10/22 folding stock has been used for long-range Bluesnarfing.
