【详细过程】
小莱不才，破解QQ群发外挂，献给像我一样的莱鸟.别乱发垃圾信息给我呀！！我们先来看一下外挂的功能，这个外挂是个测试
版，测试版的只能发一条信息（
-------------------------------------------------
您现在使用的是 [中天QQ群发王]演示版,软件支持好友群发，群群发，多QQ同时群发等！欲购买正式版者请联系 QQ:895966146！
------------------------------------------------- ）
软件要花980元才能买到正版，小莱我没有钱只能改之。小莱我决对支持正版的，所以我们给外挂添加功能好了，让这个外挂从文本文件
读取我们要发的信息，然后覆盖掉演示版的信息.
Od打开，给sendto下断点。

知道信息在哪了，现在我们来改信息.
小莱我很莱，先用vc6.0写个读文件的功能，然后用od打开看代码，然后添加到外挂里。
代码如下：
CString str="aa";
BOOL success;
DWORD numRead;
char s[200];
HANDLE fileHandle=CreateFile("hts.txt",GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
success=SetFilePointer(fileHandle,0,0,FILE_BEGIN);
success=ReadFile(fileHandle,s,200,&numRead,NULL);
编译，然后od打开

然后把这段代码copy一下粘贴到外挂.
od打开外挂，找块干净的地方，来到00412937粘贴，为了方便我粘贴了改了一下代码。
00412937 > \50 push eax
00412938 . 51 push ecx
00412939 . 52 push edx
0041293A . 54 push esp
0041293B . 6A 00 push 0 ; /hTemplateFile = NULL
0041293D . 68 80000000 push 80 ; |Attributes = NORMAL
00412942 . 6A 03 push 3 ; |Mode = OPEN_EXISTING
00412944 . 6A 00 push 0 ; |pSecurity = NULL
00412946 . 6A 01 push 1 ; |ShareMode = FILE_SHARE_READ
00412948 . 68 00000080 push 80000000 ; |Access = GENERIC_READ
0041294D . 68 B0494100 push 004149B0 ; |FileName = "g:\hts.txt" 读取的文件，找到004149B0
00412952 . FF15 10304100 call dword ptr [<&kernel32.CreateFile>; \CreateFileA
00412958 . 6A 00 push 0 ; /pOverlapped = NULL
0041295A . 8D8C24 50020000 lea ecx, dword ptr [esp+250] ; |
00412961 . 51 push ecx ; |pBytesRead
00412962 . 68 C8000000 push 0C8 ; |BytesToRead = C8 (200.)
00412967 . 8D5424 50 lea edx, dword ptr [esp+50] ; |
0041296B . 52 push edx ; |Buffer
0041296C . 50 push eax ; |hFile
0041296D . FF15 4414E94A call dword ptr [<&KERNEL32.ReadFile>] ; \ReadFile
00412973 . 5C pop esp
00412974 . 5A pop edx
00412975 . 59 pop ecx
00412976 . 58 pop eax
00412977 .^ E9 895AFFFF jmp 00408405
数据窗口ctrl+G 来到004149B0改 数据窗口的数据，改成要读取文件的路经"g:\hts.txt"
到004083FE处改为
004083FE . /E9 34A50000 jmp 00412937
00408403 |90 nop
00408404 |90 nop
代码改完了，dump出来，不要告诉我你不会dump呀。这样就给QQ群发外挂添加了新的功能，在
g:\hts.txt写在你在写的信息吧，系列（2）小莱再来分析QQ的通讯!大过年的给大家拜年了！！！
