Jo Van Bulck (@jovanbulck) is a PhD candidate at imec-DistriNet, KU Leuven (BE). His research explores security limitations along with the the hardware-software interface, with particular attention to privileged side-channel attacks in trusted execution environments. Over the past years, Jo has uncovered several innovative microarchitectural side-channel attack vectors in commodity Intel x86 processors, and more recently was among the firsts to discover transient-execution CPU vulnerabilities. In the aftermath of Spectre and Meltdown, his research on the high-profile Foreshadow attack led to a complete collapse of the intel SGX ecosystem and ultimately even dismantled widespread virtual machine and operating system isolation.
