LG smart TVs caught logging audio with screen off and snooping on local devices

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.

Or… If your neighbor has an open network… Or the TV has a secret networking protocol that allows it to talk to other LG smart devices that are on a network. Or it looks for phones that have the LG app installed… You get the idea. Once you put wireless capabilities in it, there is any number of ways it can leak your data out.

Proving it is the hard and expensive part. I don’t really have the time, skillset, or money to buy a bunch of LG or other branded IoT devices, put them in an isolated test chamber and then try to decode all the RF noise come off them.

That being said, all the technical requirements to do the things I suggested in my previous comment currently exist in those smart TVs. All that was preventing LG from doing that was consumer trust, and they’ve clearly thrown that in the garbage. At this point, based on previous behavior, it should be assumed that they will go as far as possible to exfil customer data without their consent or knowledge, until proven otherwise.

I was wondering about this type of fix. Just physically disconnecting, desoldering, or even destroying the wifi hardware and microphone(s). I’m sure they have the usual passive anti-tampering stuff, but I’m guessing it won’t brick the TV if you’re careful and know what you’re doing. Not that I know what I’m doing. But I’m capable of following a YouTube video showing me how to.
