with the US-based security vendor on November 11 urging customers to pull their management interfaces off the public internet or restrict them to known IP addresses.
Why would you EVER put management interfaces on the public internet? What terrible decisions led them down that path? VPN is so quick and easy at a minimum.
Definitely don’t this in the past (Linksys WRT54G!) but let’s be honest, the kind of people running 10yo Dlink routers aren’t going to flash new firmware, let alone OpenWRT or even know to look for it. It would have to come that way from the factory. And even then I doubt most people even do regular updates, sadly.
