Samsung TVs Accused of Covert Audio and Data Collection via Soundbars and Network Analysis
A security researcher claims some 2025 Samsung TVs collect audio through microphones or connected soundbars, and also gather geolocation and analyze local network traffic, potentially for ad targeting.
A security researcher, operating under the pseudonym "log4j," has raised serious privacy concerns regarding 2025 Samsung smart TVs, alleging that these devices collect audio data without explicit user consent. The researcher claims that a package named "always on voice" actively listens to room sounds, logging events such as barking dogs and crying babies. These logged events are reportedly counted and transmitted back to Samsung, potentially for targeted advertising purposes.
While Samsung advertises features like "Pet Care" and "Family Care" that use on-device AI to detect similar events for user alerts, log4j's claims suggest a broader, more intrusive data collection mechanism. Crucially, the researcher asserts that even on Samsung TVs lacking built-in microphones, this "always on voice" software attempts to capture audio by connecting to external devices like soundbars or Bluetooth microphones.
Beyond audio surveillance, the allegations extend to the collection of sensitive user data. Log4j claims the TV also gathers geolocation information and actively maps the local network. A service reportedly runs on the TV that analyzes traffic within the local network, raising further questions about data privacy and potential misuse. The system allegedly employs a region-specific neural network to analyze viewing habits, tracking user interactions with content, including videos watched and ads skipped on platforms like YouTube.
These allegations surface against a backdrop of Samsung's past scrutiny over its data collection practices. The company has previously faced legal challenges related to its Automatic Content Recognition (ACR) technology, which identifies on-screen content. In Texas, the Attorney General settled with Samsung, requiring express consent for ACR data collection. Similarly, class-action lawsuits in New York and California have accused Samsung of covertly recording video and audio, using machine learning to analyze this data, and leveraging it for targeted advertising or sharing it with third-party companies.
Concerns about Samsung's audio recording capabilities are not new. In 2015, the privacy group EPIC filed a complaint with the FTC, alleging that Samsung smart TVs recorded conversations and transmitted them to third parties, specifically identifying the text-to-speech company Nuance as a recipient. These historical issues lend weight to the current researcher's claims, suggesting a pattern of privacy-invasive data handling.
While log4j's specific allegations remain unverified by Samsung, the researcher warns that disabling features like ACR or voice recognition through TV menus may not be sufficient. They suggest that these settings might be incorrectly implemented or not fully honored, leaving monitoring services active. For users seeking immediate peace of mind, log4j recommends disconnecting the TV from Wi-Fi, though this sacrifices internet-based features. Alternative suggestions include using devices like Apple TV or customizable Android TV boxes with open-source software.
The ongoing debate highlights the complex privacy challenges posed by smart home devices. As manufacturers integrate more advanced AI and connectivity features, users face increasing difficulty in understanding and controlling the extent of data collection. The potential for audio, location, and network data to be harvested, even when users believe certain features are disabled, underscores the need for greater transparency and robust user controls in the smart TV ecosystem.
