【问题描述】：
我已经编写了 DLL 注入器。我使用 CreateRemoteThread 注入我的 DLL 进行处理，一切都很好。 现在我正在尝试通过未记录的函数 NtCreateThreadEx 注入 DLL 来处理。我写了注射器，但他不工作。
当我使用 32 位注入器将 32 位 DLL 注入到 32 位进程时 一切正常。 问题是当我使用 64 位注入器将 64 位 DLL 注入到 64 位进程时。
我的 DLL 代码：
#include <windows.h>
///Compilation with option -m64
extern "C" BOOL __stdcall DllMain(HMODULE hDLL, DWORD Reason, LPVOID Reserved)
{
MessageBox( NULL, "MESSAGE FROM 64 BIT DLL", "Lorem ipsum", MB_ICONINFORMATION | MB_OKCANCEL );
return 0;
}
我的 TestApp 代码
#include <iostream>
#include <windows.h>
int main()
{
std::cout << " Lorem IPSUM" << std::endl;
//HMODULE HDLL = LoadLibraryA("dll64.dll");
//std::cout << "Error: " << GetLastError() << std::endl;
while(1)
{
std::cout << "petla" << std::endl;
Sleep(5000);
}
return 0;
}
我的注射器代码：
#include <iostream>
#include <string>
#include <windows.h>
/// 64 bit OS - Windows 7
///=====================
///* In this same user context ("User")
///TYPE OF(32/64 bits)
///INJECTOR===DLL===PROCESS===RESULT
/// 32 32 32 -SUCESS
/// 64 64 64 -FALIED (error: 1300)
//Handle to process,Address of'LoadLibraryA',see DllAdr
///TO DO

}
当我使用 64 位注入器将 64 位 DLL 注入 64 位进程时，函数 NtCreateThreadEx 返回错误 1300 的代码并且我的 DLL 不执行。 我用来在 64 位架构上编译：g++ (tdm64-1) 5.1.0 我正在以普通用户的身份使用 Virus Windows 7 64 位。以管理员身份运行没有帮助。 我不知道为什么它不起作用，我做错了什么。
PS：当我使用 32 位注入器将 32 位 DLL 注入 32 位进程时，函数 NtCreateThreadEx 返回错误 1300 的代码，但我的 DLL 执行。 在 32 位版本中，TestApp GetLastError 返回代码 1114。 我用于在 32 位架构上编译：g++ (tdm-2) 4.8.1

【问题讨论】：
-
你没有检查函数是否失败；
GetLastError是没有意义的，除非 a) 函数返回其记录在案的故障代码，并且 b) 函数被记录为使用GetLastError来指示其错误代码。 -
DWORD似乎是堆栈大小的错误类型。在CreateRemoteThread文档中，它是SIZE_T（指针大小）。这将在移植到 64 位时产生问题。 -
你说得对。我将 DWORD 替换为 64 位大小的变量 (SIZE_T)。这么简单，我傻了。现在一切正常。非常感谢。
