Hello! I am a Ph.D. student at the University of Illinois at Urbana-Champaign, working under Chris Fletcher. My work lives in the intersection of Adversarial Machine Learning and Hardware Security.
Check out our recent work on Augury! Here’s a twitter thread about it too. Our experiments demonstrate the existence of a pointer-chasing DMP on recent Apple processors, including the A14 and M1. We then reverse engineer the details of this DMP to determine the opportunities for and restrictions it places on attackers using it. Finally, we demonstrate several basic attack primitives capable of leaking pointer values using the DMP.
I received my B.S. from Lawrence Technological University (in Southfield, MI), where I was a two time recipient of a Presidential Research Grant. I went on to complete my M.S. at the University of Illinois at Urbana-Champaign in the fall of 2019. My M.S. culminated in the introduction of Asynchronous Poisoning Attacks. I’ve stayed on as a Ph.D. student at UIUC.
