There is a block list you can get for pi-hole for these smart TVs. My samsung TV is the highest blocked device on my home network currently.
For those that aren't running Pi-hole, you can use NextDNS instead on all your devices and router ... and it has a Samsung blocklist that you can enable easily.
NO! Beware! It has been demonstrated by multiple research groups [0] that Pi-hole DOES NOT stop this tracking by your televisions. I hated having to type that sentence. The future is stupid.
Thanks for posting that. The smart doorbells part is especially terrifying...
I need more details on why it doesn’t, and that was one long Twitter thread. You can add more DNS entries to pihole for it to send to 0.0.0.0
Are they sending them over presumptuously and normally safe subdomains?
Before I disconnected my Samsung TV from the internet, it was responsible for the majority of DNS queries blocked by Pi-hole on my home network. I'm not sure if it blocked everything though.
Soon it won't be enough with DNS over HTTPS becoming more popular. It's probably still ok to use pihole, but if you want to be safer, you'll have to block https to 1.1.1.1 (and other providers) as well.
Or ideally, block by source not by destination.
It seems to be. I had to white list one or two domains to make it all work again. In retrospect, that may have been for a free service they since broke so maybe I should rip those out too.
