Researcher log4j reverse engineered the firmware of his Samsung smart TV and found a file describing an always-on microphone, automatic content recognition, geolocation, network mapping, targeted advertising and user-profile creation.

Cybersecurity experts say AI-assisted reverse engineering is making such discoveries easier, while stressing that most data-collection practices are already disclosed in privacy policies and user agreements. They also suggest that the collection and monetization of behavioral data may help explain why television prices have remained comparatively low for two decades. The open-source Cleanyourtv project supports 107 television models from 37 brands, but it does not fully work on Samsung televisions using the Tizen operating system.
