She felt the hairline fracture in the primary coolant manifold, not leaking yet but weeping superheated plasma into an insulated conduit. She felt the fatigue cracks in the starboard engine mount—seventeen of them, spidering out like black lightning. She felt the main reactor's magnetic bottle, which was supposed to be a perfect sphere, now bulging at the equatorial seam like a balloon about to pop.

The nomenclature itself provides clues:

This is the creepy part. When you plug a standard engineering key into a host machine, it leaves logs (Event Viewer, syslog, etc.). The KPG-111D reportedly from RAM before the OS writes the log. Security researchers have only found evidence of the key’s use via thermal imaging of the CPU die itself. kpg-111d engineering key
