Comment on We Can Still Stop California’s 3D Printer Surveillance Scheme
PancakesCantKillMe@lemmy.world 2 weeks agoI know that a Samsung teevee disconnected from the internet will try and use another appliances internet connection if it can. Gotta imagine this is possible in other devices, too.
Can you share more info on this? I’m interested in the technical aspect how this is done, specifically which devices it uses?
For instance, say, a smart speaker, may have Bluetooth and WiFi, but I’m not sure any halfway comprehensive network stack I’d even implemented that could be used as a proxy, let alone autonomously remotely reconfigured to do so.
If memory serves correctly it was another Samsung device it was leveraging which makes more sense. There were other occasions where it had once been attached to WiFi for a firmware update, disconnected and told to forget the network, but attached again to it at least twice. Took the steps to forget the network again and then powered off completely. Subsequent checks show no further connections so far.
I’ve also heard of devices that scan for open networks in the area to use. It’s also possible for them to come with a sim card and use a discounted cell collection, though not sure if any TVs are actually doing that. Could even be a virtual SIM so there’s no card to find and potentially just remove/destroy.
Its a felony, we need RF jammers.

Last year I started maintaining a MAC address whitelist on the router: if I haven’t added it, it doesn’t get in or go out. No way in hell I’m putting any household appliance on the allowed list.

Just gotta hope your neighbors don’t connect their devices, and that your own can’t reach the neighbors.
