Voltage glitching is a type of a fault injection attack where the supply voltage of a target device is modified to induce unanticipated behavior. This can include both encrypted user data, or proprietary vendor secrets. At the same time, modern devices embed more secrets than ever, which need to be protected. With the advent of affordable toolchains, such as ChipWhisperer, fault injection is no longer an attack vector that is limited to well funded and highly skilled adversaries. This research was conducted by our intern Ilya Zhuravlev, who has returned to school but will be rejoining our team after graduation, and was advised by Jeremy Boone of NCC Group’s Hardware & Embedded Systems Practice.
