Lateral Movement
Introduction
In this section, you will find some techniques in order to perform lateral movements on Active Directory infrastructuree.
Pass The Ticket (PTT)
In the Pass the Ticket technique, an attacker obtains a valid Kerberos ticket-granting ticket (TGT) by stealing it from a user or extracting it from a computer's memory. The attacker can then use this TGT to request additional service tickets without the need for any further authentication.
You can perform this technique with Rubeus.
Depending on the obtained TGS you, will only be able to perform specific tasks.
Tickets - Techniques
Service Type | Required Tickets |
---|---|
Windows File Share (PsExec) | CIFS |
LDAP Operations (DSync) | LDAP |
WinRM | HOST HTTP WINRM |
WMI | HOST RPCSS |
Powershell Remoting | HOST HTTP Depending on OS: WSMAN RPCSS |
Schedule Taks | Host |
Windows Remote Server Administration Tools | RPCSS LDAP CIFS |
Golden Tickets | krbtgt |
Overpass The Hash (OTH)
This technique allows a user to request a Kerberos TGT using its NTLM or AES/RC4 hash.
Alternative 1 - Without HIGH privileges
Alterntative 2 - Requires HIGH privileges
Then, you can use PsExec to access the machine, if the user has administrator privileges.
โน๏ธThe
-s
argument is to upgrade to "nt authority\system", but it will only work if you are going to connect as a highly privileged user.
S4U2Self Abuse (Constrained Delegation)
The exploitation is seen on the Kerberos exploitation phase.
Alternate Service Name (Constrained Delegation)
The exploitation is seen on the Kerberos exploitation phase.
