我是靠谱客的博主忧虑鱼，最近开发中收集的这篇文章主要介绍CreateRemoteThread简单应用之二，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

宿主进程 exe.exe

#include <stdio.h>
#include <time.h> 
#include <windows.h>

int foo (void)
{
    printf("foon");

    // MessageBox(NULL, "foo", "Notice",  MB_OK);
#if 0
    HINSTANCE hUser32 = LoadLibrary("User32.dll");  
    typedef int (*DllFun)(HWND hWnd, LPCTSTR lpText, LPCTSTR lpCaption, UINT uType);  
    DllFun dwMessageBox = (DllFun)GetProcAddress(hUser32, "MessageBoxA");  
#endif
    // printf("dwMessageBox GetProcAddress:%0pn", dwMessageBox);
    // dwMessageBox(NULL, "foo", "Notice",  MB_OK);

    HINSTANCE hdll = LoadLibrary("C:\Downloads\hookexe\hookdll\Debug\hookdll.dll");  
    // fnHookfoo对应的函数类型 HOOKDLL_API int fnHookdll(void)
    typedef int (*DllFun)(void);
    DllFun foo = (DllFun)GetProcAddress(hdll, "fnHookdll");
    ///printf("%pn", foo);
    foo();

    return 0;
}

int main(int argc, char* argv[])
{
    while (1)
    {
        Sleep(1000); 
        foo ();
    }
    
	return 0;
}

远程注入进程hookexe2.exe

// hookexe2.cpp : Defines the entry point for the console application.

//定义MessageBox类型的函数指针  
typedef int (__stdcall * PFN_MESSAGEBOX)(HWND, LPCTSTR, LPCTSTR, DWORD);  
  
//线程函数定义

    //只要使用api必须拦截 !!!!!!!!

    typedef int (*DllFun)(void);   // 函数指针，注意要和原函数的原型一制
    DllFun MyFun = (DllFun)pRP->dwMessageBox;  

    //就是这句有错！！！！！！！！！  
    // printf("threadProc GetProcAddress:%0pn", MyFun);
    // printf("szMsg:%sn", pRP->szMsg);
    (DllFun)MyFun();

    CloseHandle(hRemoteThread);  
    FreeLibrary(hdll);  
    return 0;  
}

对应的DLL文件源码C:\Downloads\hookexe\hookdll\Debug\hookdll.dll

// This is an example of an exported function.
HOOKDLL_API int fnHookdll(void)
{
    char msg[] = "fnHookdll"; // 常量字符串不可复制到其它进程，因此使用局部变量数组
    puts (msg);
	return 42;
}

这里一定不能直接使用 puts (“fnHookdll”); 否则不同进程中常量字符串对应的地址指针值不一致，导致hook进程复制到宿主进程后指针失效

试验步骤

1）运行宿主进程exe.exe

2) 运行hook进程hookexe2.exe

效果：

hook进程hookexe2.exe 中显示连续的fnHookdll，意味着hookexe2.exe在宿主进程exe.exe中创建的线程执行成功！
