Security researcher log4j reported that Samsung smart TVs are collecting extensive telemetry data to improve targeted advertising. The investigation focused on a 2025 Samsung model running the Tizen operating system, which records screenshots, audio, and advertising identifiers.
The system utilizes convolutional neural networks to analyze user behavior, including video playback speed, skipped advertisements, and content viewing history. The researcher suggests that background processing of this data contributes to system performance issues.
The device can capture audio even without an integrated microphone by accessing connected peripherals such as soundbars or Bluetooth devices. Engineer ngxson confirmed that the TV activates microphones for approximately five seconds during operation.
Attempts to analyze the collected data using AI tools led to the suspension of the researcher's OpenAI account. The findings highlight how modern smart home hardware leverages local and external sensors to profile user activity for commercial purposes.
