If you use btscanner, which is a Bluetooth scanner found in Backtrack Linux, a lot like I do then you will notice that the Public OUI list included is pretty far out of date. The OUI or Organizationally Unique Identifier list is what matches MAC addresses to manufacturers or vendors. This is how you can determine who produced a specific product that is talking on a network for instance a Bluetooth device that is attempting to communicate with your phone or your computer.
I have been playing around with some of the bluetooth tools within Backtrack recently and btscanner is one of the main tools I have bene using. The btscanner application in Backtrack Linux provides two bluetooth scanning functions it calls inquiry scanning and brute force scanning. Unfortunately the package installed with Backtrack 5 release 3 will crash when attempting to use it for brute force scanning however I was able to create a fix that isn’t too messy to accomplish. Below we describe the btscanner crash in more detail and provide a way to get btscanner bluetooth brute forcing operating properly.
