What happened
Polish developer Pawel Szydlowski built ZuckOff, a free app that detects Bluetooth signals from smart glasses like Ray-Ban Meta, Oakley Meta, and Snap Spectacles by fingerprinting their broadcast identifiers. It cannot tell if glasses are actively recording or who is wearing them, but gives rough proximity via signal strength. The app saw over 5,000 iOS downloads and 1,000 Android downloads in its launch month, amid growing privacy concerns after a BBC investigation traced covert filming accounts and venues banning smart glasses.
Why it matters
If you build apps or hardware in the consumer privacy space, this demonstrates a cheap, legal Bluetooth-fingerprinting approach to detecting always-on devices — a pattern worth understanding as smart glasses sales scale (Meta sold ~7M pairs in 2025). For builders in Malaysia and SEA where smart glasses adoption is rising, consider whether your venue, workplace, or product needs similar detection or policy responses.
Discussion angle
Bluetooth fingerprinting as a lightweight, legal detection layer — what other always-on devices could this technique expose, and how long before manufacturers randomize identifiers to defeat it?
