The full story
Software engineer Yannick Dixken spent a week attacking his Prusa MK4S, armed with Claude Opus 4.8 and a fuzzer, and came away with 14 findings covering roughly 23 defects in the Buddy firmware, including a chain that let him run his own code on the printer's main controller over the network. He demonstrated it by Rickrolling the printer. The findings were disclosed to Prusa, and all are patched in Buddy firmware versions after 7.0.0.
