Flash Glitching to Recovery Bootloaders

Occasionally, one comes across an interesting attack which is beautiful in both it’s simplicity and effectiveness. Earlier this week, I read a post around glitching Flash chips to get to recovery bootloaders (unfortunately, I didn’t save the link), and earlier today … Continue reading

FPGA-Driven Glitching (Regular and Crowbar) with Phase-Locked Loop

I spent the majority of this weekend working on improving my knowledge of hardware security, focussing on my experiments with glitching. In my previous posts on the topic, I had investigated how one could use two Arduinos to generate glitches … Continue reading

EM Fault Injection on a Budget

Following on from my earlier successes with glitching, I have continued investigating various methods to induce faults in hardware. One less-talked-about method is EM fault injection, which relies on using a capacitor discharge to create a temporary magnetic field, which … Continue reading
