从t0到t3 – 信息搜集
一开始，我们拥有的帐号是一个没有特权的普通账号。假设我们已经在远程或者在本地利用EXP进行了一次攻击并且获得了一个反弹回来的shell。根本上说，在时间t0，我们不知道被攻击的机器是做什么的，它和谁进行连接，我们拥有怎样的权限，甚至它的操作系统是哪个。
因此，开始的时候，我们就需要快速的搜集一些至关重要的信息，这样我们就可以了解一下我们所处环境的情况。
首先，先看看我们连接的什么类型的操作系统
C:\Windows\system32> systeminfo | findstr /B /C:"OS Name" /C:"OS Version"
OS Name: Microsoft Windows 7 Professional
OS Version: 6.1.7601 Service Pack 1 Build 7601注：中文环境下，”OS Name”为”OS 名称”，”OS Version”为”OS 版本”
接着，看下计算机名和我们使用的用户
C:\Windows\system32> hostname
b33f
C:\Windows\system32> echo %username%
user1现在我们有了基本的信息，接下来我们可以列出计算机上的其它用户，并且可以看一下我们当前用户的详细信息。从下面的结果可以看出，user1不是本地用户组Administrators的成员。
C:\Windows\system32> net users
User accounts for \\B33F
-------------------------------------------------------------------------------
Administrator b33f Guest

The command completed successfully.

The command completed successfully.这是我们暂时需要了解的关于用户的所有信息。接下来我们需要从网络方面搜集信息了。
首先，看一下网络连接和路由表。
