Challenges and Design Considerations for Finding CUDA Bugs through GPU-Native Fuzzing

Modern computing is shifting from homogeneous CPU-centric systems to heterogeneous systems with closely integrated CPUs and GPUs. While the CPU software stack has benefited from decades of memory safety hardening, the GPU software stack remains dangerously immature. This discrepancy presents a...

AI wrote my code and all I got was this broken prototype

Welcome to this week's edition of the Threat Source newsletter. Vulnerabilities within software are a persistent challenge. Software engineers inadvertently tend to make the same mistakes repeatedly, with the same entries appearing in the annual top 25 list of Common Weakness Enumerations each...

An Earth-Shattering Kaboom: Bringing a Physical ICS Penetration Testing Environment to Life (Part 1)

Building the Bench This is the first in a three part series on building and using a testing bench for ICS systems. In this series we will build a physical test bench, review program logic to find flaws, perform manual exploitation of commonly used ICS protocols such as Modbus, then develop malwar...

A tale of enumeration, and why pen testing can’t be automated

TL;DR In an engagement we found an open directory on the internet belonging to our client By enumerating it we found a zip archive with a configuration file holding usernames and passwords That file gave us access to the client’s ArcGIS instance This contained a treasure trove of information abou...
