Interrupt-oriented bugdoor programming: a minimalist approach to bugdooring embedded systems firmware

Abstract

We demonstrate a simple set of interrupt-related vulnerability primitives that, despite being apparently innocuous, give attackers full control of a microcontroller platform. We then present a novel, minimalist approach to constructing deniable bugdoors for microcontroller firmware, and contrast this approach with the current focus of exploitation research… (More)
