Researcher alleges Samsung TVs constantly listen for baby cries and dog barks
A security researcher known as @Log4j claims Samsung smart TVs continuously record audio to detect sounds like baby cries or dog barks, using the data for targeted advertising.
An anonymous security analyst identified as @Log4j alleges that Samsung’s premium smart TVs employ an always-on microphone to capture ambient sounds, specifically targeting noises like a baby’s cry or a dog’s bark for ad profiling. The claim is based on internal security documents that reveal the TV conducts ARP scans shortly after power-on and hourly thereafter, mapping devices on the home network. The researcher reports that the TV forwards this audio data to more than 400 external partners, and that opting out of data sharing does not stop connections to advertising platforms such as Google and Amazon.
Samsung maintains that its Automatic Content Recognition service is disabled by default and only operates with user consent, emphasizing its commitment to privacy. The researcher also announced plans for a tool called Ironframe intended to disable the telemetry, though installing it would void warranties. Similar privacy concerns have previously been raised about other brands’ smart TVs, highlighting broader industry issues with pervasive data collection.
Why it matters
If true, constant audio monitoring by TVs could expose private household sounds to advertisers and third parties.
