nullagentSo, funny story. Every cop's body cam is basically an AirTag. I did a talk at DEFCON explaining how you can detect and ID police body cams with your phone.
Luna Lactea@nullagent Don't most BLE devices change their MAC address like every 15 minutes though? How would you identify a specific device?
@jackemled purple hits the nail on the head. About half way through the talk I mentioned about a dozen common broadcast data fields (aka GAP fields). While the MAC may be randomized(like in Apple Countinuity) many of these additional fields are not, and can be very unique. So even when a MAC changes things like device name or manufacturer data do not. Finally some devices are so unique and rare it doesn't matter because you only see one at a time.
@nullagent Oh ok! That makes sense. An iPhone might be identifiable because the name is always something like "Kaylee's iPhone". I had an iPhone for a short amount of time & I think it automatically changed its name to say it's mine, so most iPhones should be identifiable that way.
AnarchoTechDFW@jackemled @nullagent Reminds us of this tool that, among other things, recognizes devices based on what WiFi networks they're trying to reconnect to: https://www.wired.com/story/this-anti-tracking-tool-checks-if-youre-being-followed/
