BlueRanger is a simple Bash script which uses Link Quality to locate Bluetooth device radios. It sends l2cap (Bluetooth) pings to create a connection between Bluetooth interfaces, since most devices allow pings without any authentication or authorization. The higher the link quality, the closer the device (in theory).
Bluepot was a third year university project attempting to implement a fully functional Bluetooth Honeypot. A piece of software designed to accept and store any malware sent to it and interact with common Bluetooth attacks such as “BlueBugging?” and “BlueSnarfing?”.
