Tile Bluetooth trackers leak identifying data in plain text, giving stalkers an easy way to track victims despite Life360's security promises, a group of Georgia Tech researchers warns.

A trio of researchers led by assistant professor Michael Specter found [PDF] a number of flaws in Tile trackers, they say disprove many of Tile maker Life360's security and privacy guarantees. Most shocking, say the researchers, is the fact that Tile servers continually collect tag locations, MAC addresses, and unique ID codes without end-to-end encryption, while the tags themselves broadcast unencrypted Bluetooth signals that can be sniffed to track someone else's device.

What's worse, the MAC address of Tile trackers is static - and the periodically-cycled unique IDs are only semi-randomized and are reu
