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.

There's a lot of misinformation in the comments here.

  1. LG have been caught using the Internet connection of connected devices (like windows computers) to snoop on your network.
  2. Because of that, it has access to your network even if you remove the wifi module or do not connect the TV directly to your network.
  3. Lobotomizing the TV will not necessarily fix this issue, but I still think it's a good start. It may be beneficial to switch to a different operating system or just ban the TV from accessing certain parts of the Eco system on your computer.
  4. Removing Bluetooth, wifi, and microphone modules will be beneficial in the long run because this will not be the last time a company tries this and it's not limited to LG. If you are technically inclined or can follow a YouTube video, go for it.

This all happens the moment you plug that HDMI (or DisplayPort for people who purchased an LG computer monitor) right into an internet-enabled laptop through a protocol called EDID, also known as "Extended Display Identification Data," which by itself is totally harmless!

It simply tells your operating system what kind of monitor is connected, what its capabilities are, it's serial number. That's it!

Inside Windows, when you go to Device Manager, it might not seem like much. Just a generic PnP device attached as a monitor.

Dive a little more into Device Manager, and we see where EDID does its magic; we found that this particular Microsoft Box is hooked up to some kind of Samsung monitor. Now, Samsung might have some kind of driver that would help take advantage of my monitor. But this Samsung is so old they simply do not care.

Yeah, it's installing drivers on WINDOWS.

So, caveat two is don't connect these things to an internet-connected WINDOWS machine.

Good point.

But, as others have said, if you do successfully air gap one of these things, it might stop working because a hard drive is full, or more directly because it can't phone home and is designed to lock you out in that case.

On Gamer's Nexus's video on the subject at 1:20 you'll hear how they talk about how LG accesses your network data through windows.

I think it's important to note that I didn't say in my original comment anything about it using your windows Internet connection to send and receive that data that it collects via microphone or that it may have accessed through your Wi-Fi network if you happened to connect it to that.

I think people assumed (it's early for me, my bad) that I meant it was transmitting this data that it collected over your windows computer's Internet connection but that wasn't what I was intending to claim. When you connect an LG device (Television or Monitor) you agree to allow that device access to your network and they literally say they have full access to your device both in the TOS and in device settings . They gather all the information of every single device connected to your TV. Their apps can "use all system resources" and "access your Internet connection".

0:47:00 of this video gives more detail about this. https://youtu.be/Q9uefFYe6bM?is=xKJNG-RT_j_2Tw1U

Do you have any sources for that? Not doubting it just curious about how that works.

These do not support your claims.

See the third link and watch the video.

I think you're misunderstanding what's happening. The LG TV isn't directly using the Windows internet connection. It's taking advantage of Windows Update to have Windows itself install malware as a driver update for the screen.

Which I think is actually worse, because it shows that Microsoft is complicit in this nonsense.
