Comment on Can a Smart TV piggy back the internet of a HDMI device?

It’s very very unlikely that your TV and your device connected to it both support and enable ethernet over HDMI by default. But if you are unsure you can test it by connecting and seeing if the TV is getting a connection.
Personally I opened my TV and disconnected the wifi card since in theory the TV could also just try to connect to any open wifi in the area without me knowing, but to each their own threat model.

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 that is a good suggestion.

You can sniff the network and see if the TV is connecting anywhere.

Don’t trust the TV, put short or suricata on that in passive bridge mode. Heck, even TCP-dump should see some activity when you turn on the TV.

TIL about suricata. Thanks!
