Comment on How do you isolate a printer in your homelab?
spaghettiwestern@sh.itjust.works 1 day agoWhat’s your concern with a new printer? In case 1, once set up and working how is a company going to introduce malicious features when the printer has absolutely no Internet access?

New printers can be okay. I don’t know of any specific problems with new printers except those ones with the ink subscription services. I’m saying my printer is old because it’s from another time. The only reason you’d isolate your networked printer in 2005 would be if you didn’t want other people to access your printer. Devices in your home automatically, deliberately making themselves worse on command from a cloud service was not a thing. The biggest danger with devices this old is that they probably have unpatched security vulnerabilities exploitable by anything else that gets on your network.
I have a VR headset from Facebook that is on its own VLAN because it defaults to randomizing its MAC address by default and this allowed it to bypass the firewall, phone home, and nonconsensually install new anti-features after being blocked because the setting got reset back to random when changing something. Recent LG TVs and other devices with worse preinstalled malware have been known to make requests to other devices on your network, but I’ve never heard of them using those other devices to get around network restrictions, at least not directly.

That is infuriating and I’d do the same.
Plenty of reports of devices like LG TVs acting as gateways to external devices and LG in particular seems to be a privacy nightmare. I bought a couple of appliances that advertised their smart features only to find LG’s app was required, so LG actually required both Internet access AND my exact location at all times for the app to work at all.
You may be right to be concerned even about printers though. At some point we’re going to be reading about some built-in AI hacking other network devices for Internet access and transmitting our private information to the world.
