pi-hole ftw. the vast majority of my pi-hole's DNS drops are from various Roku and Roku-like devices. Also, put all your IoT stuff onto a guest network, or if your gear supports it, on its own VLAN.
See, I just don't connect it to the network. It complained when I set it up but now it just works as a screen.
I've got a raspberry pi steaming my desktop to it with gamestream/sunshine/moonlight, and it's now as smart as my computer. It can even stream from different computers no matter where they are in the house, watch anything with stremio, and play games from them too. It's way better than using the youtube or netflix button on the TV, most of the services it offers I don't use anyway.
But actually pihole does sound like a good idea and maybe I should get that set up one of these days.
So with all the recent drama I learned that some TVs look for other open networks or other same brand TVs in range, and if found will join those networks and still share data.
So not connecting it isn't enough in all cases.
A pihole wouldn't solve this either if it was smart enough to know it's blocked and look elsewhere.
I'd be interested to see more information on that. I don't doubt companies would do that, but some good information on when it happens and how to prevent it would be useful.
So I did some looking, and as far as I can tell, there's no definitive proof of someone testing this and reporting on it. It might just be all rumors and speculation.
Thanks, I hope they don't do it. I would expect the security community to be able to find something like this, since it's not hard to hook up some devices and do packet sniffing to detect if they're talking to each other.
This would be an excellent use case for LTT's faraday cage room for instance.
