Loss Of Confidentiality

Threats to confidentiality involve, first of all, compromised Bluetooth devices. When a Bluetooth device that is part of a piconet becomes compromised (e.g., is in the possession of an unauthorized user), it may still receive information that the malicious user should not access. Moreover, the compromised device may still have network or information privileges, resulting in a compromise of the wider network as well. In the latter case, the compromised device may not only receive normal proprietary traffic but may also request that information as part of a targeted network attack. A trait of Bluetooth that makes this compromise unique is that the Bluetooth network requires device and not the user authentication to access resources. Once the device is authenticated, it is automatically connected to resources without the need for subsequent authentication. (Geoff Huston, the wireless internet)
