Summary Tile tags broadcast an unencrypted static MAC and ID, letting anyone with RF gear track you. Tile network sends tag location, MAC, and ID unencrypted to servers, enabling mass surveillance. And that appears to be what's happening to Tile trackers right now. Tile trackers apparently have significant security and privacy flaws that could allow stalkers, and even the company itself, to track users' locations, according to a new report from researchers at the Georgia Institute of Technology. We're not sure if this will actually result in changes, but in the meantime, you might want to avoid Tile trackers now that all of this is public information.
