In this blog post, we document Linux process injection techniques, and explain how to detect and mitigate them.

This post aims at giving an overview of what SELinux is, how it is implemented, and how to bypass it, from the point of view of Android kernel exploitation.

Authors: Boudewijn Meijer && Rick Veldhoven Introduction As defensive security products improve, attackers must refine their craft. Gone are the days of executing malicious binaries from di…

In this blog post, I will explain a vulnerability in the Microsoft Windows Desktop Windows Manager (DWM) Core library that I analyzed when the exploit for Core Impact was being developed. This vulnerability allows an unprivileged attacker to execute code as a DWM user with Integrity System privileges (CVE-2024-30051).

We explain how mainframes work, potential attack vectors, and what to focus on when pentesting such systems.

Introduction This is the first post of a series which regards development of malicious software. In this series we will explore and try to implement multiple techniques used by malicious applications to execute code, hide from defenses and persist. Let’s create a C++ application that will run malicious shellcode while trying to not be caught by AV software. Why C++ and not C# or PowerShell script? Because it’s much more difficult to analyze compiled binary when compared to managed code or script. For the purpose of this and following articles we will use MS Visual Studio 2017 or 2019 on Windows 10.

Introduction In this blogpost, we take a closer look at our research regarding CVE-2022-47758: a critical vulnerability impacting a very large number of Internet of Things smart devices. We could leverage this vulnerability in the lamp's firmware for unauthenticated remote code execution on the entire device with the highest privileges
