To call a function in a remote process with parameters using an injected DLL, you can follow these general steps:

  1. Inject the DLL into the remote process: Use a technique like DLL injection to inject your DLL into the target process. This will make your DLL code execute within the remote process.

  2. Resolve the function address: Once the DLL is injected, you need to locate the address of the function you want to call. This can be done using techniques like GetProcAddress or by parsing the exported function table of the DLL.

  3. Create a remote thread: Use a method like CreateRemoteThread to create a remote thread in the target process. This thread will execute the code within your DLL.

  4. Pass parameters: To pass parameters to the function, you can allocate memory in the target process and write the parameter values to that memory. Then, pass the address of this memory as an argument to the remote thread.

  5. Execute the function: In the code executed by the remote thread, use function pointers or other techniques to call the desired function, passing the parameters you prepared in the previous step.

Note that this approach involves advanced techniques and may have security implications. It's important to have a thorough understanding of the target process, its memory layout, and the potential risks involved in modifying or executing code within another process.

Additionally, keep in mind that injecting DLLs into processes without proper authorization or legal permission may violate terms of service or local laws. Be sure to comply with all legal and ethical requirements when working with remote processes.
