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.

And that's why I have a VLAN without outbound connections allowed. Still allows me to cast to the device from a separate vlan but the TV has no internet at all.

Seriously, this is the way. I did this too in about 15 mins. Also setup a simple rule to allow the vlan to reach my homeserver in a separate vlan specifically on Plex and Jellyfin ports. That's it. They cant phone home. You still enjoy your own media.

Yeah if you setup the firewall correctly you can access the TV but the TV can't access anything it self.

Same here, smart devices go on a very restricted VLAN. Most only get access to Home Assistant for control.

Even without deliberate spying from these devices letting these things loose on the network at large has always seemed a bad idea to me.

Did this a few month back. Then my Sony TV decided to hide all apps when it has no internet for a few weeks. I guess when the internal disk is filling up and it needs to phone home again. What a shit show!

So I had to connect again, but now https://play.google.com/store/apps/details?id=com.spocky.projengmenu is running, to hopefully never be coerced to go online again.

Jellyfin ftw.
