Detects a high volume of Kerberos pre-authentication failures (Event ID 4771, Status 0x18) against multiple distinct user accounts originating from a single source IP address within a short time window. This behavior is characteristic of password spraying attacks where an attacker attempts a small number of common passwords across many accounts to avoid lockouts and detection in a Windows Active Directory environment.
