Finally, a real hack! [PodeCoet] wrote in to tell us about a little fun he had recently in the workplace… He discovered the label makers everyone uses are all IP-enabled… and well, he took advantage of that.
His long but utterly delightfully written blog post is actually a tutorial on how to hack into Zebra-brand printers. From the realization of this possibility, to the first test print, to spoofing his MAC address, [PodeCoet] had a blast doing this — evident in his lovely descriptions of the events — like after he made first access to a printer over IP.
I’m now tripping absolute balls with excitement, and time seems to dilate as I rush to get to the car to drive home.
Unable to contain my excitement during the 20 minute drive, I pull over into a laneway, browse Zebra’s website on my smartphone, and download a copy of the “Zebra ZPL Programming Guide”.
Talk about excitement! Oh and did we mention he originally planned on getting fired by doing this?
He may have reconsidered though and decided on a more neutral-friendly label to mass print at work (which is an assembly line by the way). This is what he came up with:
In the end his “printer attack” lasted about 15 seconds, in which all the printers managed to spit out the same label at about the same time. He wishes he could have gotten a video clip of his coworkers reactions, but obviously this may have given him away.
Here’s a screen cap of his lovely hacking application.
In conclusion, [PodeCoet] advises you to secure your network:
Always assume someone is trying to break into your s#%t, even if you think your staff are knuckle-dragging neanderthals struggling to make ends-meet.
