Okta User Reports Suspicious Activity

This rule detects when an Okta end-user reports suspicious activity on their account. This could indicate that the user's account has been compromised or is being targeted by an attacker. The rule specifically looks for the 'user.account.report_suspicious_activity_by_enduser' event type in Okta logs. The risk score is increased if the suspicious activity event type is related to an MFA enrollment notification being sent, suggesting a potential attempt to enroll an unauthorized MFA device.
