Gamers Nexus investigation finds LG OLED TVs harvest data and pose hacking risks

An investigation by Gamers Nexus and Level1Techs, alongside independent security researchers, found LG's smart OLED TVs use Automatic Content Recognition to monitor viewing habits across all input sources and scan connected home networks, sending this data to LG Ad Solutions for targeted advertising. The team also uncovered a security flaw allowing the TVs' built-in microphone to be secretly activated for audio recording even when the set appears off, with stored recordings capable of being transmitted later once reconnected to power and internet.

LG smart TVs found scanning home networks and tracking devices even when powered off

An investigation by YouTube channels Gamers Nexus and Level1Techs, using packet capture tools and firmware analysis, found that LG TVs including the $2,500 G5 OLED can scan a household's entire local network, detecting phones, smartwatches and other unrelated devices even when those devices are never connected to the TV. Researchers say this behavior is built into the TV's native functionality rather than the result of a security flaw, and can occur even when the TV is turned off.

LG Smart TVs Found Logging Audio and Network Data Even While Offline

An investigation by Gamers Nexus, in partnership with Level1Techs and independent researchers, found that LG OLED smart TVs continuously scan local networks for nearby devices, track Wi-Fi and location data, and can record microphone audio even in standby mode. The TVs reportedly stored this data locally when disconnected from the internet and uploaded it to LG Ad Solutions once reconnected.

LG OLED TVs found recording and uploading data even while offline or in standby

An investigation by Gamers Nexus, working with Level1Techs and independent security researchers, found that LG OLED TVs continually scan local Wi-Fi networks for nearby devices, log location and network details, and send this data to LG Ad Solutions. The TVs were also found capable of capturing microphone audio during standby, storing it locally when disconnected from the internet and uploading it once reconnected, alongside using Automatic Content Recognition to identify what owners watch through apps and HDMI inputs.

LG Smart TVs Scan Home Networks and Record Audio Even When Screen Is Off

An investigation by Gamers Nexus, working with Level1Techs and independent security researchers, found that LG OLED TVs including the G5 actively scan home networks to identify phones, smartwatches and other nearby devices, while also capturing microphone audio even when the display appears off. The collected data, including Wi-Fi network names, signal strength and location details, is later uploaded once the TV reconnects to the internet and feeds into LG's advertising arm, LG Ad Solutions.
