Breaking Process Protection: Exploiting CVE-2026-0828 in ProcessMonitorDriver.sys

Introduction

A recently disclosed vulnerability CVE-2026-0828 in the Windows kernel driver ProcessMonitorDriver.sys exposes a dangerous capability: any user-mode application that obtains a handle to the device can terminate arbitrary processes, including protected system processes, without proper access-control checks. This flaw effectively bypasses the normal Windows security model that protects critical system services and security components.…

Credential Dumping from LSASS (Windows Authentication Secrets)

Original text by Raj

The article explains how attackers extract authentication secrets from the Local Security Authority Subsystem Service (LSASS) process in Windows. LSASS is responsible for enforcing system security policies, handling logins, and storing authentication data such as NTLM password hashes, Kerberos tickets, and cached credentials in memory.

Because these credentials must remain in…

Hypervisor-Based Defense (Windows Kernel Protection)

Original text by Ido Veltzman

The article “Hypervisor-Based Defense” discusses how hypervisors can be used as a powerful defensive layer to protect Windows systems from kernel-level attacks. The author explains that modern attackers frequently target the kernel using techniques such as Bring Your Own Vulnerable Driver (BYOVD) or malicious kernel modules that bypass traditional security…

Understanding Out-Of-Bounds in Windows Kernel Driver

Original text by Jay Pandya

The article “Understanding Out-of-Bounds in Windows Kernel Driver” explains how out-of-bounds (OOB) vulnerabilities occur in Windows kernel drivers and why they are dangerous from a security perspective. Out-of-bounds bugs appear when code reads or writes memory outside the boundaries of a valid buffer or structure, often due to incorrect index…

Async Windows Gone Wrong: Exploiting a Win32k Type Confusion Bug

Original text by s4dbrd

The article analyzes a Windows kernel vulnerability in win32kfull.sys involving a type confusion bug in the asynchronous window action processing path. The vulnerability occurs in logic responsible for handling window-related operations when certain internal features are enabled through Microsoft’s feature-flag system. Because of inconsistent object handling, the kernel may treat one…

Breaking the JIT: Exploiting a SpiderMonkey Type Confusion Bug

Original text by @qriousec

The article analyzes CVE-2025-14325, a vulnerability in the SpiderMonkey JavaScript engine used by Mozilla Firefox. The bug originates in the Baseline JIT compiler, specifically in the implementation of inline caches (ICs) that optimize property access operations in JavaScript. Inline caches speed up execution by remembering object layouts and reusing cached assumptions…

Inside the Payload: Manual Shellcode Analysis with Ghidra

Original text by Matthew

The article explains a practical workflow for manually analyzing malicious Windows shellcode using Ghidra and a debugger such as x32dbg. Instead of relying on automated emulators, the author demonstrates how to perform manual reverse engineering to understand the behavior of shellcode used by frameworks like Cobalt Strike. The tutorial begins with…
