What it detects
This rule detects execution of the Rubeus tool with diamond or ticket-request arguments used to forge Kerberos diamond tickets, a technique dissected by Huntress. Attackers decrypt a legitimate TGT and re-sign a modified PAC to impersonate privileged accounts while evading golden-ticket heuristics. Rubeus diamond ticket operations are a high-confidence credential-access and privilege-escalation indicator in Active Directory.
