Analyzing an automotive ECU firmware is sometimes quite challenging, especially when you cannot emulate some of its most interesting functions to find vulnerabilities, like ECUs based on Renesas RH850 system-on-chips. This article details how we managed to add support for this specific architecture into Unicorn Engine, the various challenges we faced and how we successfully used this work to emulate and analyze a specific function during an assignment.

In cryptography audits, we often find vulnerabilities labeled as low or informational, usually for "non-compliance"... So, what should we do with them?

In this blogpost, we present Hydradancer, a new board for Facedancer based on HydraUSB3 allowing faster USB peripherals emulation.

Passbolt, an Open Source Password Manager, is using the Pwned Passwords service from HaveIBeenPwned to alert users if their password is present in a previous data breach. Pwned Passwords API is based on a mathematical property known as k-Anonymity guaranteeing that it never gains enough information about a non-breached password hash to be able to breach it later. Sounds good, right?

This second article describes how to convert a Silo into a Server Silo in order to create a Windows Container. In addition, it dives into certain Kernel side Silo mechanisms.

In March 2024, SandboxAQ proposed a CTF around Post-Quantum Cryptography (and more specifically Kyber's key exchange) for the RWPQC workshop. Here is our write-up of the solutions to the challenges.

The following article explains how during a Red Team engagement we were able to develop a 1day for GLPI CVE-2023-43813 which later led to the identification of an arbitrary object instantiation leading to an SSRF referenced as CVE-2024-27098 as well as an SQL injection referenced as CVE-2024-27096.

Allbridge's maintainers, with support from Stellar Development Foundation, engaged with Quarkslab to perform an audit of Allbridge Core implementation in the Stellar ecosystem. This new implementation uses Stellar's smart contracts platform: Soroban.

Ever wanted to find a nice tool to easily represent cartography results and other graphs? The Sourcetrail tool could be a nice solution! In this blog post, we will introduce two of our tools: Numbat, a new Python API for Sourcetrail, and Pyrrha, a mapper collection for firmware cartography.

We announce the release of a new version of Blue Galaxy Energy, our white-box cryptanalysis tool implementing the BGE attack against AES. This version addresses the main limitations of the previous version.
