Nim

DLL Injection via Direct Syscalls w/ SysCaller (Nim)

This Nim example demonstrates injecting a DLL into a target process using direct syscalls via the SysCaller bindings.

---

Requirements

• Nim 1.6+ (tested with Nim 2.2.4)
• winim Nim package (nimble install winim)
• SysCaller.dll present in the same directory and built with required exports

---

Usage

$ nim c -d:release InjectDLL.nim
$ InjectDLL.exe <pid> <dll_path>

• <pid>: The process ID of the target process.
• <dll_path>: Path to the DLL you want to inject (e.g., test.dll).

Example:

$ InjectDLL.exe 4242 test.dll

---

Notes

• Make sure SysCaller.dll is in the same directory as InjectDLL.exe or in your system PATH.
• The DLL path can be relative or absolute; the injector will resolve it.
• Requires appropriate privileges to open the target process and inject code.
• Tested & Works only on Windows x64.
