Detects service ticket requests using the weak RC4 encryption type (0x17) for Kerberos, which is often abused in Kerberoasting attacks. The rule specifically looks for Event ID 4769 (A Kerberos service ticket was granted) where the TicketOptions indicate a forwardable and renewable ticket, and the TicketEncryptionType is RC4. It attempts to reduce false positives by excluding service names ending with a dollar sign, which are typically machine accounts.
Detects failed Kerberos TGT issue operations. This can be a sign of manipulations of TGT messages by an attacker, potentially indicating attempts to exploit Kerberos for credential access or to bypass authentication mechanisms.
