What happened
ZuckOff is an independent iOS/Android app that detects camera-equipped smart glasses (Ray-Ban Meta, Oakley Meta, Snap Spectacles) by passively listening for their Bluetooth manufacturer signatures — e.g. 0x0D53 for Luxottica, 0x058E for Meta Platforms Technologies, 0x03C2 for Snap. It runs entirely on-device with no account, logs all nearby Bluetooth devices, shows the evidence behind each flag, lets you mark known devices to suppress alerts, and exports logs as CSV.
Why it matters
The technically interesting takeaway for builders is the BLE manufacturer-signature fingerprinting approach: smart glasses broadcast identifiable manufacturer codes during pairing, power-on, and while worn, which means any phone with Bluetooth scanning can passively inventory nearby wearables without special hardware. Developers working on proximity, presence, or privacy tooling could reuse this detection method. The app is honest about its limits — quiet is not proof of absence, and detection is not proof of recording.
Discussion angle
How reliable is BLE manufacturer-signature detection as a building block — and what does it mean that consumer wearables broadcast enough identity to be passively inventoried by any nearby phone?
