A grey-hat hacker going by the name of Stackoverflowin says he's pwned over 150,000 printers that have been left accessible online.

Speaking to Bleeping Computer, the hacker says he wanted to raise everyone's awareness towards the dangers of leaving printers exposed online without a firewall or other security settings enabled.

For the past 24 hours, Stackoverflowin has been running an automated script that he wrote himself, which searches for open printer ports and sends a rogue print job to the target's device.

From high-end multi-functional printers at corporate headquarters to lowly receipt printers in small town restaurants, all have been affected.

Users reported multiple printer models as affected. The list includes brands such as Afico, Brother, Canon, Epson, HP, Lexmark, Konica Minolta, Oki, and Samsung.

Stackoverflowin told Bleeping Computer that his script targets printing devices that have IPP (Internet Printing Protocol) ports, LPD (Line Printer Daemon) ports, and port 9100 left open to external connections.

The script also includes an exploit that uses a remote code execution vulnerability to target Dell Xeon printers. "This allowed me to inject PostScript and invoke rouge[sic] jobs," Stackoverflowin told Bleeping about the RCE vulnerability's role.

    My printer's setup, a Canon imageCLASS, only had you press the button on the router, which shuts off the firewall for thirty seconds. I've forgotten what it said if there's no button, bought it last fall.

    But yes, it's only on when I'm printing. No sense wasting electricity.
