ZuckOff fingerprints Meta smart glasses over Bluetooth and took 255 points on HN, with an open-source Android twin
Polish developer Paweł Szydłowski built ZuckOff, which scans Bluetooth broadcasts and matches them against a catalogue of signal signatures he assembled by buying several smart-glasses models and recording their fingerprints himself, then estimates distance. It took 255 points on Hacker News on 2026-09-21 and 135 more on the Wired coverage. The honest limitation, stated by the developer, is that it cannot tell whether a camera is actually recording, only that camera-equipped glasses are nearby, and an open-source Android equivalent called Nearby Glasses does the same job.
