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.

Is this even possible or reasonable? Smart tvs are pretty dumb if you never connect them to the internet, so no issues until they decide to add 5g chips to them

    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.

    Sure prove it. At least these are proven and now your just making stuff up.

    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.

    My solution here (this is my solution; i recognize 99.5% of people would never do this) is to open up the tv and physically remove any wifi adapters or cards. Obviously not stopping them from hiding them, but being under the plastic shell is enough to stop most people

    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.

    Non-smart TVs are still available, they just cost a bit more. As for the connectivity issue, China has been caught hiding 5g chips in electrical control systems and city buses, and selling "free streaming" boxes with malware that scans networks and attacks targets deemed worth while. And all these TVs are being manufactured in China so why take the risk when you aren't going to use the connectivity anyway?
