This rule monitors for additions to the 'Domain Admins' group (Event IDs 4728, 4732, 4756) that occur within 15 minutes of an authentication event (Event ID 4624) involving accounts associated with PaperCut software on a Domain Controller. This pattern is indicative of a potential follow-on action after a PaperCut exploitation incident, where an attacker leverages initial access to perform privilege escalation.
