A new Gamers Nexus investigation found a retail LG TV actively scanning the local network for phones, laptops, smartwatches and other connected devices, while also capturing microphone audio when the screen appeared to be in standby. The investigation found voice data being stored locally even after the TV was disconnected from the network, with the queued data uploaded once connectivity returned. Researchers also uncovered webOS vulnerabilities that could potentially turn the television into a remotely controlled surveillance device. The really unsettling part isn't just the advertising angle. It's the fact that a consumer television can sit inside your trusted network, enumerate other devices, access a microphone, store collected data locally and communicate with external infrastructure. Put that same device in a corporate office, hospital, hotel or conference room and the security implications become considerably more serious. I went through the investigation in detail, including the network scanning, microphone behavior, ACR, webOS attack surface, offline data collection and practical mitigations

Is there a way to direct all the iffy traffic from the tv to a pi hole?

[–] Mr_Dr_Oink@lemmy.world 2 points 2 days ago (3 children)

Could connect the tv to the guest wifi network which would prevent it from accessing your local network. Plug in an android tv box of some variety and connect that to the network and you can cut the tv off f4om internet entirely.

If you set the pihole as your primary DNS on your router then all network traffic goes that way anyway. Set up google as a secondary in case your pihole goes down. Or configure a second pi hole for resilience and set that as the backup.

Fuck that, become ungovernable. If the pihole is down, the tv is down.

Build your own router and
Redirect all port 53 to your pihole
Block port 853 on that vlan
Block these ips on that vlan

I had a raspberry pi working as a router but when my provider gave me a zyxel router i didnt need it anymore as its super customisable.

Will i need to go back to my openwrt router to get this working? Since its saying github actions update the list?

In opnsense, fetching an alias list file is native

Zyxel gear is legit as i understand it, but i don't know their system.

The GN investigation discovered that LG makes the TVs mesh with each other as well. So even if you don't connect your LG to the internet, it can connect with other LG devices in the neighbourhood and exfiltrate data that way.

The investors must have their data

FYI guest network doesn't separate traffic from normal network. You need different vlan for that.

[–] Mr_Dr_Oink@lemmy.world 2 points 2 days ago (1 children)

my guest network is in a different vlan by default.

Afaik thats standard for guest networks. They have internet access but not local network access. Otherwise whats the point in them?

[–] Dnb@lemmy.dbzer0.com 1 points 1 day ago (1 children)

Sadly that's not how they are setup on many consumer routers.

They just act as another ssid that offer easy limits/ controls instead of a full vlan/ isolation

[–] Mr_Dr_Oink@lemmy.world 1 points 1 day ago

Wow. I might only be a little wise to this stuff but the average consumer is getting screwed.
