Service Name Substitution (Invoke-RubeusTgssub)

Description

Substitutes the service name in an existing TGS ticket to target a different service.

Overview

Substitutes the service name (SPN) in an existing Kerberos TGS ticket. Since the service name in a TGS ticket is not cryptographically protected, it can be modified to target a different service on the same host without re-requesting the ticket.

Arguments

Ptt switch Pass the modified ticket into the current session.
