LG Smart TVs Found Logging Audio and Scanning Local Devices Even When Off

A recent investigation by security researchers and technology experts has revealed that LG smart TVs actively monitor local networks and record audio even when the TV appears to be turned off. The findings come from a detailed analysis involving retail LG OLED models, including the G5, with network traffic captured using Wireshark. The TVs were observed scanning home networks for connected devices such as smartphones and smartwatches, collecting information including internal IP addresses, device names, Wi-Fi signal strengths, and location data. This information is reportedly utilized by LG Ad Solutions, the company's advertising division, which claims to track hundreds of millions of devices for targeted ads. In addition to network scanning, the TVs employ Automated Content Recognition (ACR) technology to create digital fingerprints of on-screen audio and video, allowing LG to monitor viewing habits across various inputs. New tests indicate that data collection extends beyond ACR, as the TVs were found to capture clear microphone audio while in standby mode. Even when disconnected from the internet, the devices stored voice recordings locally and uploaded them once network access was restored. The research team also identified remote code execution vulnerabilities within LG's webOS platform, which are currently being addressed through responsible disclosure. Due to the extensive data collection and security risks, experts recommend disconnecting LG smart TVs from the internet and using external streaming devices as a safer alternative. As of now, LG has not issued a response regarding these findings.
