Okta FastPass Phishing Detection
This rule detects when Okta FastPass successfully identifies and prevents an authentication attempt originating from a known phishing site. It specifically looks for Okta System Log events where the outcome reason is 'FastPass declined phishing attempt', the outcome result is 'FAILURE', and the event type is 'user.authentication.auth_via_mfa'. This indicates that a user attempted to authenticate via MFA, but Okta FastPass intervened due to a detected phishing attempt.
