A researcher reports remote code execution on a Prusa MK4S.

The researcher says he spent a week trying to break his own Prusa MK4S while testing signed upstream firmware. By the end, he had reached remote code execution, according to his account. That’s the technical result; Tom’s Hardware’s headline adds that an RCE exploit was used to Rickroll a Prusa printer. The researcher’s post is called “Never Gonna Print You Up,” and the combination makes for an unusually memorable security write-up: firmware testing that ends with a printer as the target of a Rickroll.
