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

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

Arduino-to-Arduino Voltage Glitching (look ma, no FPGA!)

Recently, I have been delving into the magical world of hardware hacking. One target has given me cause to learn voltage glitching, among other things. On the advice of friends, I ordered a ChipWhisperer kit but while it made it’s … Continue reading
