Hacking network printers

jet direct

[Irongeek] has assembled a good starting point for hacking network printers. It starts with a discussion of stock passwords and how to administrate printers using telnet. Next is finding printers using NMAP. You can actually use the JetDirect boxes as idle scan zombies to scan other systems without exposing yourself. Other topics include setting up direct IP printing, changing the display, and using Hijetter from the Phenoelit crew. The ability to capture and replay print jobs really demonstrates how insecure network printing is.

[Irongeek] is also a great source for making the most of your Zaurus and has video demos of other hacking topics.

    During college I ported lopht’s original hp display hacking code to windows. You can get the program and source for HPwin from the URL linked above

    Reminds me of this guy at school that sent five hundred pages of “FEED ME PAPER!!” to the library printer.

    Buddy of mine had tons of fun by creating fake problems (like crazy wavy text) at work for April Fool’s a couple of years ago… and documents the details- http://web.kellegous.com/scratch/2003/printers1KBXB/

    Great work as usual Irongeek. I was stoked when you showed us the page the other day, and am particularly impressed with the arp poisoning section. Something most have never considered, I’m sure. The LRS whitepaper you link to, along with your page, clearly show the seriousness of this and how to help protect yourself.

  8. Irongeek says:

    Thanks guys. By the way, that’s a pretty cool hack you buddy came up with Dick. I’ll have to link to it from my site.

    An article like this was in a recent issue of 2600. I’d consider anyone interested in this type of stuff to go check it out.

    What model and AC code do you need to enter on this page: http://www.ps2ac.com/main.asp
    to let you get one?

    this was also in Stealing The Network: How to Own the Box many years ago…

  12. Irongeek says:

    Never read them, do they have some info I don’t? If so, email me what things I should add.

    I work for HP support and I can tell you it’s barely hacking once get onto the network.
    Using the HP JetWeb Admin software you can allready scan a network for printer and change almost all settings, also the ready text can be changed, “insert coin” is my favorite.
    The autodetect works really nice, HP US has many of it’s offices connected and at one point on test installation of HP_WJA managed to find over a 1000 printers. It only took 3 days.

  14. Zanthrax says:

    it’s also great to see how much trouble people go throught to install printers directly over IP.
    Just use HP’s Install Network Printer Wizard.
