Kerberoasting: Burst of RC4 TGS-REQ (4769) for Multiple SPNs
Detects potential Kerberoasting activity by identifying anomalous behavior where a single account requests 5 or more unique Kerberos Service Principal Name (SPN) tickets within a 5-minute window, excluding common service accounts and krbtgt ticket requests. This behavior is indicative of an attacker attempting to enumerate and obtain tickets for multiple services for offline brute-force password cracking.
