Detecting Kernel Memory Disclosure – Whitepaper

Since early 2017, we have been working on Bochspwn Reloaded – a piece of dynamic binary instrumentation built on top of the Bochs IA-32 software emulator, designed to identify memory disclosure vulnerabilities in operating system kernels. Over the course of the project, we successfully used it to discover and report over 70 previously unknown security issues in Windows, and more than 10 bugs in Linux. We discussed the general design of the tool at REcon Montreal and Black Hat USA in June and July last year, and followed up with the description of the latest implemented features and their results at INFILTRATE in April 2018 (click on the links for slides).
