BlueSniper is a rifle-like tool used for 'BlueSnarfing', or in other words: a tool used to capture personal information - such as the contents of an address book, calendar etc. - from insecure Bluetooth-enabled phones.

BlueSniper works from more than a mile away and the *shooter* can even plant phony text messages in a phone's memory, or turn it into a listening device to pick up conversations in the phone's vicinity.

The device was demonstrated at the DefCon hacker conferences in Las Vegas.
