This blog post presents an overview of QBinDiff, the Quarkslab binary diffing tool officially released today. It describes its core principles and shows how it works on binaries as well as on general graph matching problems unrelated to IT security.

We present TritonDSE, a new tool by Quarkslab. TritonDSE is a Python library, built on top of Triton, that provides easy and customizable Dynamic Symbolic Execution capabilities for binary programs.

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.

This blog post is a follow-up on the announcement of Triton v0.8, where we explain how we added support for ARMv7 and provide a guideline for adding new architectures.

Off-line dynamic trace analysis offers a number of advantages, which are illustrated in this blog post through several examples using internal tools we specially developed to automate trace collection and analysis.

This blog post presents a comparison between various disassembled binary exporters.

This micro blog post introduces our research regarding symbolic deobfuscation of virtualized hash functions in collaboration with the CEA and VERIMAG.

This article aims to presentby 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.

Some experiments to mistreat the Triton concolic execution framework through simple forged C programs.
