Introducing the Car Whisperer at What The Hack
by Cudni 08:10AM Wednesday Aug 17 2005
This new tool is called The Car Whisperer and 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 hands free 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 traveling 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.
Since the attacker's laptop is fully trusted once it has a valid link key, the laptop could be used in order to access all the services offered on the hands-free unit. Often, phone books are stored in these units. I am quite certain that there will be more issues with the security of these systems due to the use of standard passkeys.
