Greetings, if you're reading this tutorial, chances are you have some interest in Intel Processor Trace (PT) and how it can improve your debugging or program analysis capabilities, but aren't sure how to get started. This is understandable, given that there aren't many practical tutorials on Intel PT and what …

My coauthors and I will be presenting our work on detecting bugs in source code using machine learning at USENIX Security 2023. Below is a preview of the abstract: In software development, it is critical to detect vulnerabilities in a project as early as possible. Although, deep learning has shown …

My coauthors and I will be presenting our work on preventing use-after-free and double free vulnerabilities at USENIX Security 2023. Below is a preview of the abstract: Critical software is written in memory unsafe languages that are vulnerable to use-after-free and double free bugs. This has led to proposals to …

I've received several questions recently about two papers I published in 2021, one at USENIX (which I'll refer to here as ARCUS) and another at CCS (which I'll refer to as Bunkerbuster). You can find these papers at the USENIX and CCS conference websites, respectively. The question people have is …

The bugs that I found using ARCUS in Halibut last year have been issued 3 CVE IDs: CVE-2021-42612 CVE-2021-42613 CVE-2021-42614 To the best of my knowledge, these bugs are now fixed in the latest release version, which at the time of writing is 1.3. Please refer to Halibut's project …

I have accepted an offer to become an Assistant Professor at The Ohio State University, starting in the Fall 2022 semester. I am currently looking to hire 1 Ph.D. student as a full-time graduate research assistant (GRA). If you are an incoming student and you're interested in cutting edge …

Over the past year I've been studying memory corruption vulnerabilities in Linux C/C++ programs, culminating in the open sourcing of a framework called ARCUS to find and explain them automatically using a combination of dynamic tracing and symbolic analysis. My work has led to two academic conference publications, one …

My coauthors and I will be presenting the paper, Automated Bug Hunting With Data-Driven Symbolic Root Cause Analysis, at CCS 2021. Below is a preview of the abstract: The increasing cost of successful cyberattacks has caused a mindset shift, whereby defenders now employ proactive defenses, namely software bug hunting, alongside …

My coauthors and I will be presenting a paper on "Validating the Integrity of Audit Logs Against Execution Repartitioning Attacks" at CCS 2021. Below is a preview of the abstract: Provenance-based causal analysis of audit logs has proven to be an invaluable method of investigating system intrusions. However, it also …

An article my coauthors and I wrote on automated large-scale market manipulation will be appearing in the November issue of IEEE Security & Privacy. It is currently available early access here. Below is the abstract: This article studies the feasibility of using a botnet to automate stock market manipulation, incorporating data …
