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 …

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 …

We have released the source code and evaluation dataset for "ARCUS: Symbolic Root Cause Analysis of Exploits in Production Systems," which will be appearing at USENIX Security 2021 in August, 2021. The paper will be ready for publication in about a month.

My coauthors and I will be presenting a paper "ARCUS: Symbolic Root Cause Analysis of Exploits in Production Systems" at USENIX Security 2021 in August, 2021. Below is a preview of the abstract: End-host runtime monitors (e.g., CFI, system call IDS) flag processes in response to symptoms of a …

Lately I've been spending a lot of time with document malware and exploring techniques for detection. Malicious documents pose interesting challenges and have become the typical first vector for adversaries to achieve a foothold. Despite this, document malware seems largely overlooked by academics compared to their executable counterparts. In short …

Georgia Tech has acknowledged me for a past vulnerability I disclosed to them.

Originally written for the Syracuse University College of Engineering blog. In the wake of the tragic shooting in San Bernardino, many questions remain and people want answers. It seemed like a breakthrough in the investigation was imminent when the FBI got their hands on one of the shooters’ iPhone, only …

I've been fooling around with IDS and specifically psad and I thought it would be fun to try installing psad on my raspberry pi. Little did I know, installing psad on an ARM processor running Arch Linux with systemd is not a simple process. It took me great effort to …
