Zero Day in Microchip SAM Microcontrollers

> The most interesting part of this attack was the discovery that the reset pin goes low for the window of time you should insert a glitch to bypass security!

Wait, does this mean you can use the reset signal directly as a glitch signal, or that the glitch has to happen for a short while within the window? If the former, that's the first time I hear of a device that provides its own bypass signal.

Excellent work!

The glitch has to happen within the window shown to you by the microcontroller. It seems to be in a different location for each microcontroller evaluated. The fact that it shows you where depending on which processor you’re attacking is pretty convenient!

Amazing!
