A hacker has managed to access the programming interface for Apple’s Airtag tracker and reprogram it with new information.

Hacker stacksmashing managed to break into the microcontroller of the Airtag and extract and then reprogram the firmware of the device.

His first demonstration was altering the data transmitted by the NFC chip in the device, as can be seen in his video below:

The hack also demonstrates a threat model brought on by the hack. Similar to leaving a “lost” USB device in front of a company, a hacker could leave a “lost” set of keys or wallet with a reprogrammed Airtag in the lobby of a company, with a reasonable expectation an employee of the company would scan it, and potentially have their iPhone compromised as the first step for a wider attack.

At present, the full capability delivered by the hack is not known yet, but given how popular the AirTags already are I expect we will hear a lot more very soon.
