What sucks is that none of this will work once the manufacturers figure out DoH.
(edited to add) I feel like the real problem will be when they start adding wireless connectivity that you can't disable. I can keep my LG off the network today by refusing to configure networking for it. I can't do that if it doesn't use/require my network...
TV still works (minus the streaming services). If you try to open the network settings the screen just shows a loading icon indefinitely.
This gets raised all the time but I just don't see it being necessary - the vast majority is happy to voluntarily provide it with an internet connection. The ones like us who fight it is a very small minority not worth spending on including cellular modems (& the associated data plan) in every TV.
I think this is way further out than people may realize. I've done pentesting in a lot of different office networks and 53/UDP is open for all, but not 443/TCP unless you're a known device.
How do you block DoH?
Hate to say it, but invisible TLS-intercepting proxies are more widely used today than they were in the 90s.
Technically, the provider could use something else, but are they so worried about ad blocking that they’ll run BGP anycast themselves?
On 443 blocking: Doesn't that defeat the purpose of having a "smart" streaming tv. If you are willing to blanket deny 443 you might as well just block the whole address and turn it into a dumb tv.
And on that note. I have set up unsecured wifi access points before and seen the neighborhood samsung tvs eagerly use it to send their nefarious spyware payload.
im telling you these non-standard unrootable bricks companies keep creating needs to stop. need to balance security and right to own your own device!! let alone enviromental considerations.
