Detecting Bluetooth Surveillance Systems

Presented at THOTCON 0x6 (2015), May 14, 2015, 11:30 a.m. (25 minutes)

Departments of Transportation around the country have deployed "little white boxes" -- Bluetooth detectors used to monitor traffic speeds and activity. While they're supposedly anonymous, they detect a unique ID from every car and phone that passes by. In this presentation explore the documentation on these surveillance systems and their capabilities, then build a Bluetooth detector and recorder out of less than $200 of open-source hardware and software, as well as turn it on the surveillance system and try to detect and map the detectors as well.
