介绍几种常见的payload，并且以漏洞利用的角度探讨它们的功能
bind shell
bind（绑定型）shell用于提供远程shell连接。在成功利用了目标主机上的安全漏洞后，并且成功执行了shellcode程序以后，渗透人员可在目标主机上的特定端口上运行bind shell，以让其他主机继续控制这台主机。攻击人员可以使用基于TCP连接的标准输入输出隧道工具（例如Netcat）连接带被攻破的主机，通过bind shell继续实施控制。它的应用场合与Telnet服务器/客户端十分相似，主要适用于以NAT方式连入网络的渗透人员、攻击人员的设备与目标主机之间有防火墙的情况，即适用于无法从被测主机直接连接到攻击人员主机IP的各种情况。

Module options (exploit/windows/smb/ms08_067_netapi):

metasploit通过集成的payload处理程序自动连接到bind shell。我们可以自己编写shellcode。利用exploit程序安装bind shell，然后再通过Netcat这类第三方工具连接到bind shell。
reverse shell
reverse（反射型）shell与绑定型（bind）shell截然不同。reverse shell不是在目标机器上绑定端口，被动地受理攻击人员的机器连接，而是采用反弹的方法，让被测主机主动的连接攻击者的IP和端口，并提供一个shell。reverse shell适用于被测主机采用NAT方式连接网络的情况，或者被测主机受防火墙保护而使渗透人员不能从外网直接访问被测主机的各种情况。

meterpreter
meterpreter是一种先进的、隐蔽的、多功能的、可动态扩展的payload，它可在目标主机的系统内存里注入DLL（注入的DLL完全不会以文件形式存在）。此外，它还支持在运行期间加载脚本和插件。在漏洞利用的后期阶段，它的动态加载特性极大地拓宽了渗透人员的作业空间，方便了提权、保存系统账号、进行关键记录、驻留性后门顾问、开启远程桌面等各种操作。默认情况下，meterpreter shell会采用全程加密的通行方式。
