    I have seen this with Jet Direct Cards before. Have you ever ran a checker, such as Fluxy against a jetdirect that has TCPIP enabled?
    depending on which model it is it can have in excess of 30 diffrent useraccounts/password combinations.
    there are also a few unix based utilitys I have seen around(I will try and find some) that allow you to change setting even change the messages that are displayed on some HP printers

       - ONGOING "F***ing University of Rochester" defacement and destruction
       - OLD Fluxay SQL & NETBIOS attacks
       - NEW Port 3389 WTS attacks & HP LaserJet defacements/reconfigurations
    I am continuing to hear about newly-hacked sites, that have experienced
    identical attacks, using MS SQL Server holes and a "rochester.bat"
    script previously discussed on the "incidents" list, to delete most
    files, and, if there is an IIS web server installed, replace its home
    page with text reading "F***ing University of Rochester" (please excuse
    the language).
    Victims to date have included several systems at UC Santa Cruz, a U Penn
    Cancer Center third-party hosted web site, a headhunting firm, and publishing 
    *** If any more sites are hacked in this fashion, I would appreciate hearing
    about it -- please send email to abuseat_private ***
    Many of you have been experiencing similar sets of attacks via SQL, NETBIOS,
    and various other ports.  The University of Rochester experience includes these
    common features:
    * Scanning for and exploitation of Microsoft SQL server weak or blank
      'sa' passwords (port 1433)
    * Scanning for and explotation of weak passwords on Windows
      administrator accounts (netbios ports 137-139, 445, 524)
    * installation of back door software on compromised machines (typically
      RemoteNC or FluxaySensor)
    * Most common tool for the above has been Fluxay from  It offers very easy one-click
      exploitation and back-door installation.
    IN ADDITION, the same attackers have been exploiting or trying to
    exploit the following.  I point them out separately because there has
    not been much discussion yet about port 3389 exploits in particular, so
    I am keenly interested in getting more information (and in alerting the
    rest of you).
    * Scanning for and exploitation of something in Windows Terminal Server
      (port 3389).  Exploit tool and attack method unknown.  (Please all if
      evidence turns up.)
    * Defacement and reconfiguration of HP LaserJet printers (ports 23,
      9100, 80), addresses set to collide with production web and dns
      servers.  Expoit tool and attack method unknown.  We have at least
      one claim that a printer with up-to-date firmware and a password set
      still got exploited, so perhaps it's not all weak passwords.
    *** If you see similar attacks, I would be grateful for additional
    information you could provide regarding the attackers (e.g.  source of
    attack, for correlation purposes), and their methods (e.g.  copies of
    attack tools left behind).  I would especially welcome information on
    the port 3389 mystery exploit. ***
