Researchers at George Mason University have discovered a way to track just about any Bluetooth device using Apple’s Find My network. The hack, dubbed nRootTag, can be used by hackers to make any Bluetooth device into “unwitting homing beacons.”
The researchers figured out a way around how an Apple AirTag changes its Bluetooth address using a cryptographic key, which protects the AirTag from being hacked. The researchers developed key search methods to create a compatible Bluetooth address that the key adapts to, bypassing the secure key.
