Part 2 of a series about participation in the Pwn2Own Toronto 2023 contest.

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.

In this blog post we present PASTIS, a Python framework for ensemble fuzzing, developed at Quarkslab.

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.

Parity Tech mandated Quarkslab to audit XCM version 2 (XCMv2), a cross consensus communication mechanism. This messaging protocol is a cornerstone of the Polkadot ecosystem as it enables communications between chains on a network. This blog post summarizes few security aspects related to this technology and its implementation. The full audit report is available in PDF format at the end of this article.

The Litecoin Foundation mandated Quarkslab to audit the implementation of the MimbleWimble protocol in the Litecoin blockchain. This protocol acts as a sidechain in which privacy of the transactions is improved compared to the privacy on the classical chain.

This post is a quick vulnerability report summary for a vulnerability we found while fuzzing the TCP/IP stack CycloneTCP.

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