No it doesn’t? They can do all these things just fine over a LAN connection (assuming it routes externally).
If you can firewall your LAN - you can also firewall your WiFi.
- rolandog 20d agoExcept some of the TVs try to connect to unprotected hotspots, or piggyback through ISP's routers' hidden secondary SSIDs. Which even opens people's data and ambient conversations finding their way to the manufacturer or advertisers through war-driving.
- nickthegreek 20d agoname one.
- lazide 20d agoI think it’s currently a theoretical issue, not a proven one. Do you have any concrete examples? IMO, the moment a device starts doing that, I’m setting it on fire.
- wat10000 20d ago“If you can firewall your LAN - you can also firewall your WiFi.” Huh? Your WiFi is (part of) your LAN.
- lazide 20d agoThat’s what I’m saying, yes.
- wat10000 20d agoOk, I don’t understand your point, then. If a device works locally then you can firewall it and block any nasty stuff phoning home. If it runs everything through the manufacturer’s servers then you can’t firewall it without disabling it entirely.
- lazide 20d agoRead the thread. People are saying ‘if it connects to the LAN it’s safe’. I’m pointing out safe or not has nothing to do with it being on a LAN or not.
- wat10000 20d agoI’m completely lost. I’m not talking about safe, I’m talking about how routing everything though a server gives a lot more control to the manufacturer and they’re loathe to give that up.
- lazide 20d agoI’m pointing out that has literally nothing to do with LAN or Wifi. It’s a problem with having literally any (unfiltered) network access at all. Though even filtered, you’re susceptible to bypass attacks. Notably, a device can even route all command and control through a cloud service, including sending copies/hashes of all accessed content AND also serve just local (as in physically connected) media/content, if it has a network connection. This has been an issue since BluRAY at least, where players have the capability to check physical media licensing and deny/brick BluRAY media based on network updates of the keys, and could run Java apps which had network access. So at least 20 years? It is a big reason why there was resistance to BluRAY vs DVD, as DVD was a relatively dumb player. The only way to prevent that is to firewall off or physically disconnect any network access. Which is getting harder to do with cheap LTE modems. In this example, for instance, I bet these LG TV’s will happily send all this info even if no one is using any network or app based media streaming at all.
