It looks like you're interested in understanding how to create a default alert for "Phish delivered due to ETR override" in Microsoft Defender. Here's a brief overview of the process:
- Understanding ETR Override: Exchange Transport Rules (ETR) are used to apply specific actions to messages as they pass through the transport pipeline. An ETR override can allow a phishing email to be delivered despite other security measures
- Creating the Alert:
- Navigate to Microsoft Defender: Go to the Microsoft 365 Defender portal.
- Create a New Alert Policy: Under the "Alerts" section, create a new alert policy.
- Define Conditions: Set the conditions to trigger an alert when a phishing email is delivered due to an ETR override. You can specify the criteria based on the message properties and the actions taken by the ETR.
