Investigation Claims LG TVs Collect User Data and Audio in Standby Mode

An investigation by YouTube channels Gamers Nexus and Level1Techs, conducted with independent cybersecurity researchers, alleges that LG TVs capture audio and scan local networks even when the devices are offline or in standby mode. The researchers report that the televisions collect information about the Wi-Fi network, including the geographic location, signal strength, and a list of other connected devices such as smartphones and smartwatches. According to the investigation, audio files recorded while the TV was in standby are sent to LG as soon as the device connects to the internet. The researchers also claim that the TVs continue to listen for up to 15 seconds after a voice command ends and that a hidden second microphone remains active even when the primary microphone is disabled in settings.

LG Electronics has denied the accusations that the devices record conversations in the environment. The company stated that voice data is only processed when the remote control button is pressed or a wake word is recognized. LG further explained that the ability to identify devices on the same network is intended to enable features like content sharing and smart home functionality. The company added that the automatic content recognition feature is optional and that data sharing for advertising can be disabled.

Beyond audio and network scanning, the investigation suggests that the TVs can track content displayed on the screen, including via HDMI connections, for advertising purposes. The researchers also claim to have found vulnerabilities that could allow remote code execution, though these details were shared only with LG. This issue follows a legal action by the Texas Attorney General against several TV manufacturers, including LG and Samsung, regarding the collection and monetization of viewing data.
