LG smart TVs caught logging audio with screen off and snooping on local devices

summary

LG smart TVs use an invasive data collection system that monitors local networks and records audio even when the screen is off. This information is used to map home devices and track viewing habits for targeted advertising purposes. The scale of this surveillance is significant, involving millions of devices globally. Because of these privacy violations, security experts recommend disconnecting these TVs from the internet entirely.

key points

1. The TVs actively scan local area networks to identify and map other connected devices like smartphones and smartwatches. This data is fed into LG's advertising arm to create detailed profiles of users and their home environments.
2. Microphone audio is captured in standby mode and stored locally if the internet is disconnected, then uploaded once connectivity is restored. This reveals that the devices are recording users without their active knowledge or consent.
3. The devices utilize Automated Content Recognition to fingerprint on-screen audio and video across all inputs. This allows the company to log exactly what the user is watching regardless of the source.
