in today’s world, unfortunately it has become more common to place hidden cameras, audio recorders or other forms of spying surveillance devices in private locations without consensus and/or knowledge.
As techniques get more mature and affordable for everyone, it becomes hard to detect such attacks on surveillance.
Example locations: hotels, hostels, public toilets
Example person groups: spying voyeurs, neighbors, stalkers
Probably the most prominent tracking device are Apple AirTags. Fortunately, there are existing apps on F-Droid which can be used for detection (like AirGuard).
Hence I would be curious: Do corresponding counter-surveillance apps for F-Droid exist to detect other spying devices than AirTags? Which hardware requirements are needed (electro-magnetic sensors)?
Or can’t mobile devices provide sufficient protection with currently used sensors and an extra device would be needed?
Curious about the answers,
