This article provides a brief overview of how Microsoft Open Management Infrastructure (OMI) works, as well as two vulnerabilities that the Quarkslab Cloud team identified through fuzzing techniques.

A journey into the Pwn2Own contest. Part 1: Netgear RAX30 router WAN vulnerabilities

Falco's maintainers, with support from Cloud Native Computing Foundation, engaged with Quarkslab to perform an audit of Falco, an open-source cloud-native runtime security tool. The goal of the audit was to assist the Falco maintainers to increase their security posture using static and dynamic analysis (fuzzing in particular) and was organized by Open Source Technology Improvement Fund, Inc.

In this blog post we discuss the details of two vulnerabilities we discovered in the Trusted Platform Module (TPM) 2.0 reference implementation code. These two vulnerabilities, an out-of-bounds write (CVE-2023-1017) and an out-of-bounds read (CVE-2023-1018), affected several TPM 2.0 software implementations (such as the ones used by virtualization software) as well as a number of hardware TPMs.

We are releasing a new cryptanalysis tool based on a known paper but without known open source public implementation so far.

This blog post presents a post-exploitation approach to inject code into KeePass without process injection. It is performed by abusing the cache resulting from the compilation of PLGX plugin.

The OCI Image Specification is the core concept behind container images. However, not much is known about it even though container technologies are becoming more and more popular. In this blogpost we will demystify it and look into its internals.

The internship season is back at Quarkslab! Our internship topics cover a wide range of our expertise and aim at tackling new challenges, namely:

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 article introduces a kind of eBPF program that may be used to monitor userspace programs. It first introduces you to eBPF and uprobes and then explores the flaws that we found in uprobes.
