CAPEC-667: Bluetooth Impersonation AttackS (BIAS)
An adversary disguises the MAC address of their Bluetooth enabled device to one for which there exists an active and trusted connection and authenticates successfully. The adversary can then perform malicious actions on the target Bluetooth device depending on the target’s capabilities.

Overview
CAPEC-667 (Bluetooth Impersonation AttackS (BIAS)) is a detailed-level attack pattern catalogued by MITRE in the Common Attack Pattern Enumeration and Classification (CAPEC). It describes a recurring method attackers use to exploit software weaknesses.
How the attack works
The phases an attacker typically follows to carry out this attack.
- Step 1Explore
[Find disguise and target] The adversary starts the Bluetooth service on the attacking device and searches for nearby listening devices.
- Knowledge of a trusted MAC address.
- Scanning for devices other than the target that may be trusted.
- Step 2Experiment
[Disguise] Using the MAC address of the device the adversary wants to impersonate, they may use a tool such as spooftooth or macchanger to spoof their Bluetooth address and attempt to authenticate with the target.
- Step 3Exploit
[Use device capabilities to accomplish goal] Finally, if authenticated successfully the adversary can perform tasks/information gathering dependent on the target's capabilities and connections.
