Process injection is a powerful technique often associated with security research, malware analysis, and advanced software development. In this talk, I’ll dive into the mechanics of process injection on Windows, showcasing how developers can harness low-level Windows API (WinAPI) calls in C# to interact with system internals. I’ll introduce my open-source tool—designed to simplify and demonstrate process injection—walking attendees through its architecture, implementation, and real-world applications. With live demos, I’ll illustrate how surprisingly accessible these low-level operations can be using C#, debunking the myth that such techniques require complex C++ or Assembly knowledge. Attendees will leave with a clear understanding of process injection, hands-on insights into WinAPI usage, and an open-source tool they can explore, extend, or adapt for their own projects.
