p. 62 : Five Fault Injection Attacks, By Colin O’Flynn
A walk-through of Dmitry Nedospasov’s work (and even more proof of how this works) is available on his blog: this work was also replicated by on his blog: blog/bootloader-bypass-part1
Using voltage fault injection on Linux platforms is relatively easy to do – I’ve got an example video of this using a simple low-cost crowbar circuitry available here for example. This type of attack results in the waveform as in Figure 2 in the article.
The shorting out of a pin and resulting console is shown in Photo 1 and Photo 2 respectively in the article for the Philips Hue hub. You can see a video of this here at to get an idea for timing.
