Thirteen years. That’s how long the Xbox One held its “unhackable” reputation. Microsoft engineers apparently said it with a straight face — that this console, this piece of 2013 consumer electronics, had been designed to be impenetrable.

A hacker named Bliss just voltage-glitched that claim into oblivion.

The technique is delicious in its elegance: voltage glitching involves briefly spiking or dipping the power supply to a processor at precisely the right moment, causing it to misfire. Not crash. Misfire. You’re not overwhelming the security — you’re whispering lies to silicon at the exact microsecond it’s checking credentials. The hardware panics, makes a mistake, and suddenly unsigned code is running at every level of the system.
