我已经编写了 DLL 注入(inject)器。我使用 CreateRemoteThread 注入(inject)我的 DLL 进行处理，一切都很好。 现在我正在尝试注入(inject) DLL 以通过未记录的函数 - NtCreateThreadEx 进行处理。我写了注入(inject)器，但他不工作。

当我使用 32 位注入(inject)器将 32 位 DLL 注入(inject)到 32 位进程时 一切正常。 问题是当我使用 64 位注入(inject)器将 64 位 DLL 注入(inject)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;
}

我的注入(inject)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)

当我使用 64 位注入(inject)器将 64 位 DLL 注入(inject)到 64 位进程时，函数 NtCreateThreadEx 返回错误代码 1300 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 我正在以普通用户身份处理 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(inject)器将 32 位 DLL 注入(inject)到 32 位进程时，函数 NtCreateThreadEx 返回错误代码 1300 但我的 DLL 执行。 在 32 位版本中，TestApp GetLastError 返回代码 1114。 我用来在 32 位架构上编译:g++ (tdm-2) 4.8.1

最佳答案

当我使用他将 DLL 注入(inject)我的用户空间中的其他进程时，我的注入(inject)器正在工作(我以普通用户身份工作) 但它不工作时 我正在注入(inject) csrss.exe(或其他系统的进程)。 我得到错误代码 5 - 访问被拒绝，当我以管理员身份运行注入(inject)器时，我得到错误代码 0(成功？)但我的 DLL 没有中止进程 (中止() - 我尝试做 BSoD)。

我读到有关 session 分离的信息，我认为这是我遇到问题的原因，所以我有一个问题:我如何破解 Windows :) 如果这是不可能的，我可以将 DLL 作为普通用户注入(inject)到管理员上下文(或其他普通用户的进程)中进行处理吗？

关于C++ 和 Windows - NtCreateThreadEx 函数的 DLL 注入(inject)不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35924578/
