FreeBSoD: Leveraging Language Models to Find and Exploit Kernel Bugs (Part 2 of 2)
Overview In the first installment of this series, I walked through how I leveraged large language models to assist in identifying several vulnerabilities in the FreeBSD kernel, including a stack-based buffer overflow assigned CVE-2026-3038. This raised a natural follow-up question. Can language models effectively write exploits for memory corruption vulnerabilities? This article explores that question. […]
FreeBSoD: Leveraging Language Models to Find and Exploit Kernel Bugs (Part 1 of 2)
Overview Earlier this year, a team at Praetorian was building Constantine, our automated 0-day discovery engine. I wanted to find techniques worth folding into it, so on the side I started poking at the FreeBSD kernel with Claude Code, running on Opus 4.6, which was the latest Opus model at the time. A few days […]
Enter the WasmForge: Compiling Sliver into WebAssembly
In our last post we used a Claude skill to systematically beat down VirusTotal detection rates on offensive security tools, with a brief mention of a new loader we’d been using to apply those techniques in bulk. This post is about that loader, which we call WasmForge. WasmForge is, from the user’s perspective, a build […]
