This TV probably wasn’t spying on you.
I run a local resolver in my house and I’ve previously written about using it, together with a response policy zone, to block Windows 10 computers’ attempts to connect to Microsoft’s telemetry servers. I’ve added these lines to the zone in an effort to stop my telly connecting to the more suspicious-sounding domains:
log-ingestion-eu.samsungacr.com CNAME . devicelog.samsungcloudsolution.net CNAME . prderrordumpssm.samsungcloudsolution.net CNAME .
I’m being selective because I still want to use the ‘smart’ features of the set—I still want to watch Netflix and YouTube on it, for example. There’s more work to be done as can be seen from this list of domain lookup attempts by my TV in a period of five days. The Samsumg ones are the most interesting; some are obviously needed for the normal function of the TV’s smart features, but others might be blockable without disturbing them. If you find any that I haven’t listed, or know anything more about them, please leave a comment!

Ran across this because I got to looking at my chatty Samsung TV. WOW! Talk about spying on us!!! The TV keeps sending stuff to “log-ingestion”. Also I noticed that apps NOT BEING USED are checking in frequently (such as to Amazon…really??? I can only think profiling what I watch to figure out what I might want to buy)
These marketing folks are becoming more invasive every day. What I do and what I watch is MY BUSINESS!
I’m setting up selective blocking as well.
Thanks for your list. Here is partial of mine when I’m watching Pluto (DNS lookups removed to reduce noise):

Since Samsung’s Smart TV’s started to show ads and automatically install the even more hated McAfee, I decided to accept the fight. The standard router I use at home is not very useful, however it allows me to add dns-entries and guide those requests to a non existing address.
The firewall at my work however is very good at showing which traffic the Samsung tv generates, and indeed: That’s a lot. The set of DNS-rules do help, but it also seems to connect to a bunch of IP-addresses directly using TCP port 5223. So I blocked that too.
The best way is probably to disconnect the tv from the internet and use another solution for the apps. Another workaround may be to block all traffic, and start allowing specific traffic.

Found this website while searching what ‘samsungcloudsolution.net’ was. I was having issues on my smart TV playing Hulu and this was one of the DNS lookups that was blocking HULU from video playback . I also notice all the items mentioned above (as far as chatty smart TV). Its interesting how much data these devices are sending while on (and what data); (Time on, time off, what was watched, for how long, at what volume, etc.)
Good luck guys, stay safe

Thankfully I have a machine always running, serving network shares, now running my DHCP server and an DNS Server (PiHole) this rules will help shut up my chatty tv thx.

In addition to all the UNAUTHORIZED traffic from my Samsung TV there is one which absolutely floods my logs and makes NO sense as I have assigned a STATIC IP address to the TV yet I am getting non-stop DHCP requests attempting to use “localhost” which is beyond stupid.
dhcp[1729]: not giving name localhost to the DHCP lease of 192.168.1.24 because the name exists in /etc/hosts with address 127.0.0.1″
