The rule "Auth0 Push Notification Fatigue" monitors for excessive push notifications sent to a user, which may indicate an attempt at push notification fatigue - a common tactic where attackers overwhelm a user with multiple notifications in order to bypass Multi-Factor Authentication (MFA). This rule is enabled and has a high severity rating due to the potential risk of compromising user accounts. If the threshold of 5 push notifications is exceeded within a 30-minute period, an alert is triggered, prompting an investigation into whether these notifications were initiated due to legitimate user actions or malicious intent.
