> In one demonstration, Columbia professor Salvatore Stolfo and colleague Ang Cui showed how a hijacked system could be sent commands that would overheat the printer’s fuser, causing the paper to brown, smoke, and sometimes even catch fire.

> Every time a printer accepts a job, it checks for software updates. Since LaserJet printers manufactured before 2009 don’t verify the source of the update, nefarious hackers can easily intercept these requests and implant their own “updates” – a flaw that left security experts aghast.

> “First of all, how the hell doesn’t HP have a signature or certificate indicating that new firmware is real firmware from HP?” said Mikko Hypponen, head of research at security firm F-Secure, when told of the flaw.

Way to go HP.

I was just reading this on nakedsecurity…All we have is HP laserjet printers, one of which actually was smoking, but I don’t think due to this exploit.

I’ve got one old laserjet on my desk, and 2 more in my department. Couldn’t even tell you how many in the building and we’re a small company.
