TIL about suricata. Thanks!

Please don’t give them any ideas. I know that some ISPs already provide routers with hidden SSIDs which are kind of used like a mesh. TVs, in collaboration with those ISPs, them can communicate.

Security by obsoleteness

Ethernet over HDMI

Thanks for this. Looks like it’s a rare protocol.

Excerpt from the article

If you have an HEC-compatible device, it will most likely be self-described somewhere in the user’s manual. Unfortunately, this technology is rarely implemented, and you would be hard-pressed to find a device that uses HEC. Through our research, we were unable to find any modern consumer device that uses HEC.

I am slightly relieved.

But if you are unsure you can test it by connecting and seeing if the TV is getting a connection

I might be a bit paranoid but I suspect that in such a scenario, the TV will report that there is no connection but will keep on sending data to remote servers.

Fortunately in my area there are no open WiFi networks but disconnecting the WiFi card is a good suggestion. Wish we had physical kill-switches in all devices.
