Donut

Donut is a position-independent shellcode generator that creates x86, x64, or AMD64+x86 shellcode for loading and executing various Windows payloads from memory.

The tool supports multiple payload types including .NET Assemblies, PE files, and other Windows executables. It generates shellcode that can load these payloads directly from memory without requiring them to be written to disk.

The generated shellcode is position-independent, meaning it can execute from any memory location without requiring specific memory addresses. This characteristic makes it suitable for various exploitation scenarios where memory layout may be unpredictable.

Donut allows users to pass parameters to the loaded payloads, providing flexibility in how the executed code receives input. The tool supports multiple processor architectures, enabling compatibility across different Windows systems.

The shellcode generation process converts standard executable files into a format that can be injected and executed within existing processes, making it useful for post-exploitation activities and payload delivery mechanisms.
