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.
Gotcha, find its card and rip it out.
In the not so distant future, people will begin turning their houses into faraday cages to ensure nothing can access the outside unless given proper permission.
This is the way.
You could set up a dummy LAN with no internet access for the tv. Unless it actually has more than one network card, it would need to be able to have the ability to virtualize network interfaces to connect elsewhere, and I really doubt these TVs are that smart.
Ah, gotcha. That would seem like overkill if that's what would be needed.
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.
can't you set a password so it can't join willy nilly?
That would only work until your neighbor leaves their guest WiFi open.
