Comments on: Fun Had With Networks – Shared Printers http://thesnarky.com/2007/03/09/fun-had-with-networks-shared-printers/ The Words of the One Who Calls Himself a Philosopher Tue, 26 Oct 2010 22:13:34 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Ammon http://thesnarky.com/2007/03/09/fun-had-with-networks-shared-printers/comment-page-1/#comment-4979 Ammon Fri, 16 Mar 2007 21:30:52 +0000 http://thesnarky.com/archives/146#comment-4979 I discovered something similar with the U of Arizona network a few years back. We somehow cobbled together a list of what we guessed amounted to >75% of the HP printers on campus. It was then confirmed that almost none of them had any sort of password protection and would accept print requests over normal TCP/IP. This meant that I could sit at home and print stuff out on my desk at work, etc... It also meant that we figured out how to anonymously and simultaneously bomb every one of the printers on our little list of love with randomly selected Shakespearean sonnets. Not that we ever pushed the button... except on our own network, and then only to test that it worked... but yeah. And that's w/o running Java apps on the printer :) I discovered something similar with the U of Arizona network a few years back.
