Ugh. So blocklists were not enough. Time to isolate my telly on the router.
If your television is connected to any network at all its already too late.
Amazon Sidewalk - even if you didn't connect it, it could still be spying
What is this? I have a Sony TV that's not connected to the internet so I thought I was safe.
I don't know if any TVs are actually using it, but Amazon Sidewalk is a form of LoRa, low power, low bandwidth, long distance communication. It's designed to let non-internet connected devices phone back home. I hear it is very popular with shipping trackers because you can put a small device in a pallet and have it send it's GPS back for free. I'm not sure it would support the GBs of data TVs are phoning home with each month, but it could certainly send some data home.
Even then it's rumoured some brands of TV try to connect to Bluetooth connected devices to connect to the net. I think that was Samsung.
Wouldn't that require bluetooth tethering?
You could try to host your DNS, change the router DNS to that and then spend a while to see to which addresses the TV talk to and block them, it's probably time consuming but if you have that time, it can work
unless LG skips DNS entirely and hard codes its IPs.
Oh right that might be a problem, but in that case we can make a subnet (as i suggested on another reply) and block any connection that isn't on specific addresses or IPs
Yeah, I know. I have a blocklist for LG and other common brands compiled by someone else on my router DNS adblocker. But considering how sneaky they are with collecting information they should stay the fuck away from, I bet they have mechanisms to get around their common ad domains for the data that matters.
Do a whitelist.
Yeah you are right, you are better of staying away from LG but if you already have one, you could make a subnet for the TV (and/or other IoT devices) with a DNS whitelist to block every domain except Youtube or whatever else is used
I have a separate and isolated net for all my IoT and smart home devices but things like the telly, amp, media player etc need to have some network access. Makes me tired that this kind of fiddling is necessary.
