LG smart TVs caught logging audio with screen off and snooping on local devices (www.notebookcheck.net)

An investigation by Gamers Nexus found LG smart TVs sweep local networks to map phones and nearby devices. Tests also showed the sets can capture microphone audio with the screen off — they then upload data once reconnected to the internet.

I ran a packet capture on my TV as I left it turned off overnight.

They wake up in the middle of the night, do "stuff" then go back offline. Like a zombie.

LG's Windows drivers were doing that. LG deserves the blame and can't be trusted, but ditto for Windows itself.

I have a led backlight connected my TV's usb port and I've noticed it comes on randomly when the TV is turned off, then turns off. This happens couple of times throughout the night, when the TV is clearly doing something
