Golden/Silver Ticket Attack

Overview

The ticket attack abuses the service account's password hash.

Golden Ticket Attack

The Golden Ticket Attack abuses the krbtgt account's password hash to issue the Kerberos ticket-granting tickets as the KDC to access the resources.

After the adversary gets the account krbtgt's password hash, it can

  • create a valid Kerberos TGT for any user in the domain and

  • manipulate that user’s PAC to gain additional privileges.

Silver Ticket Attack

Attackers can mint service-granting tickets without communicating to the KDC, if they get the password hash for the service account.

Tools

With a service account's password hash, we can mint a service-granting ticket without interacting with the DC.

We can use the saved ccache file to authenticate to the service later.
