Quokka: A Fast and Accurate Binary Exporter

Quarkslab is open-sourcing Quokka, a binary exporter to manipulate a program's disassembly without a disassembler. This blog post introduces the project, details some parts of its inner workings, and showcases some potential usages. Quokka enables users to write complex analyses on a disassembled binary without dealing with the disassembler API.

Slaying Dragons with QBDI

This article aims to present a simple use of our Dynamic Binary Instrumentation framework QBDI which has recently been publicly released following a talk at 34C3. We will resolve, step by step, a CTF challenge by analyzing an obfuscated binary using QBDI, thus showcasing some of the nice features it offers. This blog post was written last year during my internship at Quarkslab, where I discovered the wonderful (but not so simple) world of Dynamic Binary Instrumentation.
