Bluetooth eavesdropping

Martin Herfurt, in his article Introducing the Car Whisperer at What The Hack about the tool The Car Whisperer exposed one more Bluetooth security flaw.

What this tool does is it 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.

Its time to tell people how poorly they are driving :-?
