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.

Following our presentation at Black Hat USA, in this blog post we provide some details on CVE-2022-20233, the latest vulnerability we found on Titan M, and how we exploited it to obtain code execution on the chip.

In the first part of the blogpost, we tackled the issue of 1v1 conversations, and it is now time to see how this applies to 1vMANY: group chats! We will give an overview of current solutions, and then have a look at the Messaging Layer Security working group.

In this blogpost we present our brand new version of binbloom, a tool to find the base address of any 32 and 64-bit architecture firmware, and dig into the new method we designed to recover this grail on both of these architectures.
