Advanced .NET Exploitation

Instructor:  Sina Kheirkhah
Dates:  June 15 to 18 2026
Capacity:  25

In this 4 day training course, we will be exploiting 15+ remote code execution chains (total of 25 single bugs), these vulnerabilities will all be unique in their style and target real world softwares in the class, we'll walk you through bypassing mitigation, discovering and chaining complex vulnerabilities, the tricks and techniques based on each target and many more exciting subjects. This is going to be 32 hours of intensive reverse engineering and exploitation to develop your intuition for finding and exploiting bugs in .NET environments.

Prerequisites

A good attitude towards learning and basic knowledge of reverse engineering, although the course is about reverse engineering managed code, having prior reversing experience (x86, etc) has a big advantage

Hardware/Software Requirements

• 300GB free disk space
• 16GB of ram or more
• A x64 windows host operating system (no linux, no mac)
• Do not use a ARM based machine for this workshop
• VMWare Workstation Pro (make sure its the Latest Version)
• Basic familiarity with a scripting language like Python, Bash, etc.
• Medium familiary with any language that is .NET based, (C#, F#, etc)
• Basic knowledge of "any" reverse engineering is required (x86, etc)
• A decent internet connection (hotspot, etc)
