In the Phish email view, this list typically contains legitimate URLs. Attackers include a mix of good and bad URLs in their messages to try to get them delivered, but they make the malicious links look more interesting. Email clustering analysis via similarity and malicious entity queries ensures that email problems are fully identified and cleaned up, even if only one email from an attack gets identified. You can use links from the email cluster details side panel views to open the queries in Explorer or Advanced Hunting to perform deeper analysis and change the queries if needed.

During the email clustering analysis, all clustering queries will ignore security mailboxes set up as Security Operations mailboxes in the Advanced Delivery policy. Similarly, the email clustering queries will ignore phish simulation education messages that are configured in the Advanced Delivery policy.

Neither the SecOps nor the PhishEdu exclusion values are shown in the query to keep the clustering attributes simpler and easier to read. This exclusion ensures that threat intelligence and operational mailboxes SecOps mailboxes and the phish simulations PhishEdu are ignored during threat analysis and do not get removed during any remediation.

When opening an email cluster to view it in Explorer from the email cluster details, the PhishEdu and SecOps mailbox filters will be applied in Explorer but will not be shown. The investigation email analysis calculates email threats and locations at the time of the investigation to create the investigation evidence and actions.

This data can get stale and outdated when actions outside of the investigation affect the emails involved in the investigation. For example, security operations manual hunting and remediation may clean up emails included in an investigation. Likewise, deletion actions approved in parallel investigations or Zero-hour auto purge ZAP automatic quarantine actions may have removed emails.

To ensure investigation actions are up to date, any investigation that has pending actions will periodically re-run the email analysis queries to update the email locations and threats. Email-based evidence in the Evidence and Response tab for an incident now displays the following information.
