时间调整

ntpdate 192.168.198.40

对80端口web服务进行扫描，没有有用的结果

smb服务扫描

也没有匿名用户可以访问的共享目录

139 rpc连接
没有发现用户名，组等信息

用户名枚举

尝试多个字典

先发现了这几个用户名

经过测试info ： info有效凭证
枚举smb共享

查看homes

发现很多用户名，可以记录下来。然后是netlogon共享

发现一个和密码相关的文件，我们下载到本地，然后查看wsuscontent

发现一个和匿名相关的文件，我们下载到本地

查看文件发现是一个密码

这个密码不是，前面我们拿到的用户的密码

是disconvery的密码

AS-REP Roasting和Kerberoasting

没有

Kerberoasting成功，发现了两个服务账户，尝试离线利用一下

但是失败，换个思路，dc开启了mssql服务，尝试一下

发现凭证是有效的，登陆

登陆成功

mssql利用

尝试开启xp_cmdshell但是权限不够

枚举一下数据库，发现有一个hrappdb有点意思，但是我们无法使用

看看能不能冒充其他用户，在 MSSQL（Microsoft SQL Server）中，“冒充其他用户”的机制主要是通过 EXECUTE AS 实现的，也被称为 执行上下文切换 或 用户模拟（impersonation）

利用，枚举表


枚举数据，得到一组新的凭证

Bloodhound

发现我们得到的hrapp-service用户有Genericwrite权限，进行查看发现新的攻击链

利用一

利用脚步自动获取GREEN用户的hash，然后尝试利用

成功，密码为haze1988

利用二

发现是rdp组

我们现在可以以GREEN用户的身份修改smith用户

成功，密码修改为Password123！

拿到shell

发现该用户有管理员权限，使用xfreerdp登陆


使用smith的凭据可以开启一个高权限shell

SeBackupPrivilege提权

通过

whoami /piv

发现有SeBackupPrivilege权限

SeBackupPrivilege 是 Windows 权限之一；
拥有这个权限的用户可以 绕过 DACL（访问控制列表），读取本不属于自己的文件；
它的原始用途是支持备份软件访问系统上所有数据

利用：

导出NTLM hash

登陆

或者

成功
