VIEW RULE IN DATADOG VIEW SIGNALS

Set up the okta integration.

Goal

Detect when Okta raises a phishing detection with FastPass origin check.

Strategy

This rule monitors Okta for when a phishing detection with FastPass origin check has been raised. Okta provides a platform detection for when a user enrolled in FastPass fails to authenticate via a real-time adversary in the middle (AiTM) phishing proxy.

Triage and response

1. Extract the attackers IP address {{@network.client.ip}}.
2. Determine if any other users have authenticated from this address.
3. If yes, clear any user sessions and reset passwords if the users entered a password as part of the authenitication flow.
4. Begin your organization’s incident response process and investigate for any account takeovers.
