I read an interesting report from Dark Reading today regarding hacking Bluetooth and how USB can play a roll. (Not that hacking for the dark force is anything cool) You don’t hear much about Bluetooth hacks because the tools needed (sniffers) start at about 10Grand.
A couple of security engineers where able to use a Cambridge Silicon Radio chip-based USB dongle, some flash memory and Bluetooth 2.x technology and some code hacked from a commercial Bluetooth sniffer to hack into a device’s communication via the Bluetooth signal.
There was no specific USB hack How-To information but the point is that if a simple USB dongle can be construed to do Bluetooth hacking then security risks for not only communication but device control could become a huge big problem.
