以接管游戏发送数据的操作它的代码为基础进行修改

通过通过逆向分析确定游戏明文接收数据过程分析得到 0x10617FD7 位置是调用recv函数之后接收到数据处理一个数据包的函数位置，它调用的函数不是虚函数表里的函数了，而是一个普通的函数，如下图红框位置，它调用的是0x10618480（0x10618480是函数地址）函数

然后这个函数不知道是由于编译器优化还是什么原因，它是用eax传递的连接对象，但它本质上还是thiscall（一个类调用它的成员函数就是thiscall，Visual Studio里c++里的this就是取ecx寄存器里的值），所以调用的时候要特殊处理（因为类调用成员函数用的是ecx）

用游戏生成一个接收到的数据包，这里的数据包时聊天数据的数据包，用于模拟服务器欺骗客户端

游戏种发送的聊天数据：

修改一下数据包：原本时0x31现在改成0x32

效果图：成功欺骗了客户端，让客户端接收了伪造的数据

GameProc.cpp文件的修改：修改了 InitInterface函数，新加 _OnRecv函数

#include "pch.h"
#include "GameProc.h"
#include "extern_all.h"// typedef bool(GameWinSock::* U)(char*, unsigned);bool _OnRecv(HOOKREFS2) {unsigned* _esp = (unsigned*)_ESP;_EAX = WinSock->RecvPoint;WinSock->OnRecving((char*)_esp[2], _esp[1]);return true;

}

GameWinSock.h文件的修改：新加 _OnRecv函数指针变量，OnRecving函数、OnRecv函数、vatble变量、un变量、RecvPoint变量

#pragma once
