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.

They speculated it could connect anyway via some router brands, that allow specific devices to connect automatically. Since cases like that happened.

So if it's range of neighbours' routers, you might be fucked anyway. They didn't confirm it though, to be clear.

Yea I could see them using Amazon sidewalk or xfinity open access points to get around the no connection thing. But that should be easily discovered if they do.

That... seems like a poor design choice security wise. Might as well carry it into DEF CON wearing a shirt that says "PWN ME DADDY" at that point.

Then you can watch all the depraved porn you want to, and the Government will think it's coming from the house with the insecure wifi

No, it sends mac addresses. It knows exactly which tv and where, doesn't care that it connected via your neighbor or some public wifi.

not necessarily, MAC is a layer 2 protocol, and your router (NAT or no NAT) operates on layer 3. Routers are supposed to overwrite the MAC address with their own when they forward a packet.

It's always possible for the unit to put its own identfying info in the payload. But you didn't do anything silly like register the TV, did you?

The dns entry uses a unique subdomain with that info hashed into it
