[C＃代码注入要处理的64位dll

Question

我有一个代码可以将32位库（C ++）注入到外部32位进程中：

[DllImport("kernel32")]
        public static extern IntPtr CreateRemoteThread(
          IntPtr hProcess,
          IntPtr lpThreadAttributes,
          uint dwStackSize,
          UIntPtr lpStartAddress, // raw Pointer into remote process  
          IntPtr lpParameter,
          uint dwCreationFlags,
          out IntPtr lpThreadId
        );

        ...

        public static bool InjectDLL(Process p, string dll)
        {
            IntPtr bytesout;
            Int32 LenWrite = dll.Length + 1;
            IntPtr AllocMem = (IntPtr)VirtualAllocEx(p.Handle, (IntPtr)null, (uint)LenWrite, 0x1000, 0x40);
            WriteProcessMemory(p.Handle, AllocMem, dll, (UIntPtr)LenWrite, out bytesout);
            UIntPtr Injector = (UIntPtr)GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");
            IntPtr hThread = (IntPtr)CreateRemoteThread(p.Handle, (IntPtr)null, 0, Injector, AllocMem, 0, out bytesout);
            return true;
        }

但是如何修复该代码以将64位库注入64位进程？上面的代码不适用于64位进程和dll。

谢谢！

Answer 1

您的injector，您的目标进程和DLL必须全部为x64。

原因是由于此行：

GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");

将返回x86 LoadLibrary（）的地址，而不是x64地址。
