Hack Bluetooth Connection

Carwhisperer is a new tool, which allows people equipped with a Linux Laptop and a directional antenna to inject audio to, and record audio from bypassing cars that have an unconnected Bluetooth handsfree unit running. Since many manufacturers use a standard passkey which often is the only authentication that is needed to connect.

This tool allows to interact with other drivers when travelling or maybe used in order to talk to that pushy Audi driver right behind you ;) . It also allows to eavesdrop conversations in the inside of the car by accessing the microphone.
