NimPackt-v1 - Nim-based Assembly Packer And Shellcode Loader For Opsec And Profit

NimPackt-v1, Nim-based Assembly Packer And Shellcode Loader for Opsec And Profit. This branch is no longer maintained and comes without any form of warranty or support. PRs are always welcome. NimPackt is a Nim-based packer for .NET (C#) executables and shellcode targeting Windows. It automatically wraps the payload in a Nim binary compiled to Native C, making it harder to detect and reverse engineer. Main execution methods include `Execute-Assembly` and `Shinject` with optional evasive measures like API unhooking, AMSI patching, and disabling ETW. Features include static syscalls, NTDLL.dll refreshing, ETW and AMSI patching, AES encryption, cross-platform compilation, and integration with CobaltStrike for payload generation
