While putting together my previous post on battery information for Bluetooth devices, I was curious about more information regarding these devices. Turbo didn't track much other than the MAC address so I decided to take a peek at the SANS FOR585 for path information. While stumbling through the "misc" folder I came across the file at the following path:
It's a simple text file that contains some information about the Bluetooth adapter for the phone itself as well as Bluetooth connected devices and their setup information. As we can see with the Android 11 test image from Josh Hickman, he had some paired devices including a Fitbit Charge 3 and a Nissan Rogue.
Heather Mahalik has a great publication out on DFIR Review on Android Auto and Bluetooth connections and helped me confirm some of the reasons why I wasn't seeing timestamps for some entries. Working with Alexis Brignoni (all credit due to him and his Python skills), he was able to assist in turning around a working ALEAPP parser for this information in less than 24 hours, so go get that update!
