Hardware Power Glitch Attack (Fault Injection) - rhme2 Fiesta (FI 100)

LiveOverflow demonstrates how to perform a voltage glitch attack on an Arduino using an FPGA to bypass an infinite loop.

We perform a fault injection on an arduino board to break out of a endless loop. We drop the power for a very short amount of time so the microprocessor calculates something wrong.
