Okta User Failed Number Challenge During Push Notification
This rule detects when an Okta user fails a number challenge during a push notification for multi-factor authentication. This specific failure occurs when the user provides an invalid response to the number challenge, leading to the authentication attempt being blocked. This could indicate an attacker attempting to gain access to an account by repeatedly sending MFA push notifications, hoping the user will eventually accept or incorrectly respond to the challenge.
