Bio: Kit is currently pursuing a PhD in cyber security at The University of Birmingham. Her research interests include embedded hardware and software based fault injections. Kit has been building and researching a tool to enabled testing and evaluation of hardware fault injection using software emulation. Kit currently runs the University’s Ethical Hacking Club: AFNOM which encourages students to learn offensive security in a friendly, informal environment.
Talk: Plundervolt: Pillaging and plundering SGX with Software-based Fault Injection Attacks, Kit Murdock
Many modern processors expose privileged software interfaces to dynamically modify the frequency and voltage. These interfaces were introduced to cope with the ever-growing power consumption of modern computers. In this talk we show how these privileged interfaces can be exploited to undermine the system’s security. We present the Plundervolt attack – demonstrating how we can corrupt the integrity of Intel SGX computations.
