Exploitation of Vulnerabilities
In part three of this four-part series, VerSprite’s security researchers examine real-world examples of reversing and exploiting Windows named pipe servers within applications using a custom vulnerable application. The methods covered to achieve this goal is through using both dynamic analysis and static analysis.

N-Day Vulnerabilities and Exploits
Have you ever come across undocumented Windows structures that need to be reverse-engineered in order to perform a vulnerability analysis? In this post, we will demonstrate how to update these using IDA Pro and HexRays Decompiler for the ESTROBJ and STROBJ structures on Windows 10 x64.

Reverse Engineering
After investigating an information leak within Windows 10 in more detail, we decided to see how feasible it would be for an attacker to create an IDAPython script that could discover CVE-2019-1436 and other similar memory leaks automatically.
In part II of this three-part series, we dive deeper into hands on examples of identifying usage of named pipe servers within applications using a custom vulnerable application. The methods covered to achieve this goal is through usage of both dynamic and static analysis.
