According to a team of researchers at Columbia University, hackers can alter the firmware of HP printers—and potentially any printer connected to the Internet—and use it to steal personal data or even make the printers blow up.

The hack involves giving the printer instructions to repeatedly heat up its fuser—normally used to dry wet ink on paper—until paper in the machine catches fire. And once the malware reaches the printer, it can’t be removed, so the printer will have to be discarded. 

HP, in particular, has come out and said that their newer printers have stronger built-in security measures. The problem is most consumers don’t really ever upgrade to new printers until their current one stops functioning or now—in these cases—explodes.
