manual map injector in csharp

To manually map an injector in C#, you can follow these steps:

1. Load the target process: Use the System.Diagnostics.Process class to start the target process you want to inject into. You can specify the target process name or its process ID.

main.cs
Process targetProcess = Process.Start("target.exe");
// or
Process targetProcess = Process.GetProcessById(processId);

2. Allocate memory in the target process: Use the VirtualAllocEx function from the kernel32.dll library to allocate memory in the target process.

main.cs
IntPtr targetProcessHandle = OpenProcess(ProcessAccessFlags.All, false, targetProcess.Id);
IntPtr baseAddress = VirtualAllocEx(targetProcessHandle, IntPtr.Zero, bufferSize, AllocationType.Commit | AllocationType.Reserve, MemoryProtection.ExecuteReadWrite);

3. Write the DLL path to the target process: Use the WriteProcessMemory function from the kernel32.dll library to write the path of the DLL you want to inject into the allocated memory of the target process.

main.cs
string dllPath = "C:\\path\\to\\your.dll";
byte[] dllPathBytes = Encoding.Unicode.GetBytes(dllPath);
IntPtr bytesWritten;
WriteProcessMemory(targetProcessHandle, baseAddress, dllPathBytes, dllPathBytes.Length, out bytesWritten);
229 chars
5 lines

4. Load the DLL into the target process: Use the CreateRemoteThread function from the kernel32.dll library to create a remote thread in the target process that loads the DLL.

main.cs
IntPtr loadLibraryAddr = GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryW");
IntPtr threadHandle = CreateRemoteThread(targetProcessHandle, IntPtr.Zero, 0, loadLibraryAddr, baseAddress, 0, IntPtr.Zero);
WaitForSingleObject(threadHandle, INFINITE);

5. Clean up resources: Close the handles and free the allocated memory when you are done.

main.cs
CloseHandle(targetProcessHandle);
VirtualFreeEx(targetProcessHandle, baseAddress, 0, FreeType.Release);

Please note that manual mapping is a more advanced technique and should be used responsibly and in accordance with the law. It may also be considered suspicious by some antivirus programs.

Also, make sure to include the necessary DllImport and other relevant declarations at the top of your code file to use the functions from the kernel32.dll library.
