Detects anomalous Kerberos TGT (AS-REQ/AS-REP) activity using Event ID 4768. The rule identifies two scenarios: (1) TGT requests that fail with specific status codes indicating issues with the account (disabled, nonexistent, or locked), and (2) TGT requests that utilize RC4 encryption with classic Golden Ticket flags (renewable/forwardable). These patterns are indicative of potential Kerberos abuse, including attempts to use compromised accounts or forged golden tickets.
