Wide Open for Attack
I switched over to a new router recently. Set up WPA-2 encryption on the wireless access. Don't want the neighbors stealing my Internet bandwidth. Then I had to move all my printer over to use the new router. I got a ton of printer. But I use three of them wirelessly all the time. Two of them are cheap Brother printers. The other is a color HP.
Turns out the easiest way to configure the printer network configuration is to connect to the printer over the network. Each of these guys seems to have a built in mini-web server. You just figure out the printer's IP address. Then you put that address in the browser URL bar. Presto. You are greeted with a tons of menus to control the printer.
Now changing the printer network configuration requires you to enter a username and password. The problem is that I never changed those passwords from the factory defaults. Doh. This is just like leaving the default passwords on my wireless routers.
Now I figure there can't be too much damage done if someone comes in and mucks around with my printer configuration. I could always press the button that returns them to their factory configuration, then lock them down. But why wait? Lock them up tight I say.
