In this SySS (https://www.syss.de/) proof-of-concept video, an example of a voltage glitching attack is demonstrated using the developed iCEstick Glitcher for a Lattice iCEstick Evaluation Kit [1].
A voltage glitching attack is considered a non-invasive hardware fault injection attack, in which an attacker tries to manipulate the behavior of a targeted device in a beneficial way by modifying its supply voltage.
By triggering a successful glitch, it may be possible to bypass security features like read-back protections, to activate disabled debug interfaces, or to bypass authentication or integrity checks.
In this demo video, a security vulnerability in the code read protection (CRP) feature of NXP LPC-family microcontrollers is exploited which was found and published by Chris Gerlinsky in 2017 [2].
Our simple voltage glitcher implementations iCEstick Glitcher [3] and iCEBreaker Glitcher [4] are based on and inspired by Dmitry Nedospasov's FPGA-based Arty Glitcher [5] which was also published in 2017 together with a blog article series [6-8] and by Grazfather's glitcher [9, 10] for the iCEBreaker FPGA.
