Rustic64 is a 64-bit, position-independent shellcode template inspired by the design principles of Stardust. Unlike traditional methods, this template adopts a fully position-independent architecture tailored for the Windows environment, providing a modern and flexible solution for position-independent implant development.
A common challenge with position-independent implants is managing global variables or raw strings. Rustic64 addresses this by introducing a global instance to maintain state across different parts of the shellcode, enabling seamless access to APIs, modules, configuration data, and more.
In addition, Rustic64 incorporates a custom allocator that uses the native NT Heap API. Initialized with RtlCreateHeap and managed through functions like RtlAllocateHeap and RtlFreeHeap, this allocator allows for the use of heap-allocated types like Vec and String in a position-independent context, integrated via a global instance.
This project is primarily a personal learning journey in modern implant development. It is shared in the spirit of collaboration and growth, inviting feedback, suggestions, and improvements from the community.
This project is intended for educational and research purposes only. It is designed to showcase a modern approach to implant design using Rust and should not be used for any illegal or unethical activities. The code provided here is a demonstration template, and the creators of this repository are not responsible for any misuse of this information.
