The 'Okta Phishing Detection with FastPass Origin Check' analysis rule is designed to identify failed authentication attempts through Okta associated with phishing attacks. Specifically, it monitors logs for events indicating that multi-factor authentication (MFA) was attempted but failed due to FastPass declining a phishing attempt. This detection tactic is crucial, as it targets adversaries employing phishing techniques, particularly real-time proxies aimed at credential theft. If this behavior is established as malicious, it can lead to unauthorized access to accounts and sensitive data, which might facilitate further attacks, including lateral movement within the network. The search query leverages Okta's event logs to track these incidents, reinforcing proactive monitoring of user authentication successes and failures that could signify an ongoing phishing campaign.
