Yep, and to take this a step farther (I love doing that ), you can actually ftp to HP print servers and upload *tons* of garbage to the print server rendering it useless. Today you find HP jet direct print servers with a Webserver, FTP service and Telnet service. All are wide open out of the box and the great thing about HP is they give you the Jet Admin software, which, you guessed it, out of the box is wide open. This means that you can down printing services enterprise-wide in minutes if you don't take the necessary steps to lock down a print server.

One more side note: When I started at my current position, I found print servers (i.e. Jet Direct Print Servers) used as mini WAREZ servers. They have enough space to house toolz and other nasty business.

Keep your eyes on other internal hardware in the months to come. You'll see an increase in attacks on devices that admins typically don't think about.
