The article explores techniques and tools for reverse-engineering modern web browsers, focusing on the intricacies of browser architecture, security mechanisms, and debugging processes. It highlights the importance of understanding browser internals for both security researchers and developers aiming to enhance their web applications. Practical examples and methodologies are provided to aid in the reverse-engineering process.

The blog discusses PatchGuard, or Kernel Patch Protection (KPP), a critical security feature in Windows that protects the kernel from unauthorized modifications. It explains how PatchGuard operates asynchronously to monitor key kernel structures, triggers a blue screen of death (BSOD) upon detecting tampering, and delves into its initialization process and the challenges of reverse engineering it. Additionally, the article hints at potential bypasses for this security mechanism.

Apple released a security patch for CVE-2025-43300, addressing an out-of-bounds write vulnerability in the ImageIO framework that could be exploited in zero-click attacks. The article provides a detailed root cause analysis of the vulnerability and the changes made in the patch, focusing on the modifications in the RawCamera file and the implications for image processing. Researchers have previously explored the vulnerability, revealing its connections to JPEG Lossless compression in DNG files.

RIFT (Rust Interactive Function Tool) is a suite designed to aid reverse engineers in analyzing Rust malware, consisting of an IDA plugin static analyzer, a generator for creating signatures, and a diff applier for applying binary diffing results. It is crucial to use RIFT within a secure virtual machine environment to avoid security risks, and the tools are primarily tested on Windows and Linux systems. Community contributions are encouraged to enhance the tool's capabilities.

Automated Function ID database generation in Ghidra streamlines the reverse engineering process for binaries lacking symbol information by allowing analysts to create and apply function signatures. The article discusses utilizing scripts and PowerShell to extract object files from static libraries, import them into Ghidra, and generate function signatures, enhancing the clarity and efficiency of vulnerability analysis in software.
