We are pleased to announce that if you are using third-party report message solutions in Microsoft Outlook, such as Knowbe4, Hoxhunt, and Cofense, you can now configure Defender for Office 365 to automatically forward these suspicious messages to Microsoft for analysis. A prerequisite for using this is to already have set up the third-party user report tool on Outlook for your end users and that tool is forwarding the user report to an exchange online mailbox within the organization. We do not recommend using the exchange transport rule for it. To enable this setting, you must do the following: Go to User reported settings in the Microsoft Defender portal, select Monitor reported messages in Outlook, and then select Use a non-Microsoft add-in button. In the Reported message destination section, select Microsoft and my reporting mailbox, and then provide the email address of the internal Exchange Online mailbox where user-reported messages by the third-party add-ins are being routed to. If the third-party vendor follows the guidance for message submissions format, Defender for Office 365 will submit these messages automatically to Microsoft for analysis. The analysis results from Microsoft are displayed on the User reported page in the Defender portal. Alerts are automatically generated for user-reported messages in Defender for Office 365. If you have Defender for Office 365 Plan 2, Automated investigation and response (AIR) is also automatically triggered for user-reported phishing messages. These alerts and their investigations are automatically linked to Defender Incidents, assisting security teams with automation for triage, investigation, and response. Submitting these messages to Microsoft for analysis provides a response of this analysis to security analysts and helps improve Defender for Office 365 filters.

We are excited to announce the GA release of auto-remediation of malicious messages through automated investigation and response (AIR) expanding this powerful tool and deliver on full end to end automation of key SOC scenarios. AIR works to triage, investigate and remediate and respond to high-impact, high-volume security alerts providing tenant level analysis to increase customer protection and optimize SOC teams. With this enhancement, customers will be able to configure AIR to automatically execute remediations for messages within malicious entity clusters saving SOC teams time and further expediting remediation by removing the need to for SOC teams to approve these actions! To highlight the key user submission scenario, in addition to AIR completing triage, investigation, remediation identification, and end user feedback responses, customers may now configure AIR to take this a step even further to automatically execute on identified remediations. Auto-Remediation Action When AIR recognizes a malicious file or URL, it creates a cluster around the malicious file or URL grouping all messages that contain that file or URL into the respective cluster. The automated investigation then checks the location of the messages within the cluster and if it finds messages within user’s mailboxes, AIR will produce a remediation action. With the auto-remediation enhancement, if the customer has configured the cluster type to auto-remediate, this action will automatically be executed without the need for SecOps approval - removing identified threats at machine speed! Auto-remediated clusters showing in action center history with decided by stating automation: Configuration Auto-remediation will be controlled by a configuration within Settings > Email & Collaboration > MDO automation settings. Within the message clusters section, organizations may specify which types of message clusters they would like to be auto-remediated: Similar files: When the automated investigation recognizes a malicious file, it creates a cluster around the malicious file grouping all messages that contain that file into the cluster. Selecting this checkbox will opt the organization into auto-remediation for these malicious file clusters. Similar URLs: When the automated investigation recognizes a malicious URL, it creates a cluster around the malicious URL grouping all messages that contain the URL into the cluster. Selecting this checkbox will opt the organization into auto-remediation for these malicious URL clusters. The next configuration is for the remediation action, designating soft delete as soft delete is currently the only action supported through AIR. Auto-remediation of malicious entity clusters configuration found in settings>Email & collaboration>MDO automation settings: Note: Customers interested in auto-remediation must turn it on through the MDO automation settings page as it will not be on by default. Auto-Remediation Action Logging The Defender portal provides several ways for customers to review remediation actions to stay cognizant of the actions executed. These include within the investigation, action center, email entity as well as threat explorer and advanced hunting. Should customers disagree with the action executed, the ability to move the messages back to mailboxes is available as well based on configuration and timing.

Part 2: Build custom email security reports and dashboards with workbooks in Microsoft Sentinel
Security teams in both small and large organizations track key metrics to make critical security decisions and identify meaningful trends in their organizations. Defender for Office 365 has rich, built-in reporting capabilities that provide insights into your security posture to support these needs. However, sometimes security teams require custom reporting solutions to create dedicated views, combine multiple data sources, and get additional insights to meet their needs. In January of this year, we shared an example of how you can use workbooks in Microsoft Sentinel to build a custom dashboard for Defender for Office 365. Today, we are excited to announce the release of an updated version of the Microsoft Defender for Office 365 Detections and Insights – Microsoft Sentinel workbook. Over the past few months, we have received feedback from numerous security teams, offering a multitude of ideas for new insights, updated visuals, and improved structure for the workbook. We have incorporated these suggestions into this update to enhance the experience for all users of the Microsoft Defender for Office 365 Detections and Insights workbook. What’s new? We have changed the workbook structure and divided visuals and insights related to the same topic to be on their own tab. We have also added many new visuals and updated existing visuals. Using tabs for easier navigation Simply use the tabs now on the top of the workbook to navigate between the various insights' groups. Notable changes: False Positive and False Negative Submissions insights are separated to have their own tab A new tab added for Quarantine Insights. The complete list of tabs is: Detection Overview | Email - Malware Detections | Email - Phish Detections | Email - Spam Detections | URL Detections and Clicks | Email - Top Users/Senders | Email - Detection Overrides | False Negative (FN) Submissions | False Positive (FP) Submissions | File - Malware Detections (SharePoint, Teams and OneDrive) | Post Delivery Detections and Admin Actions | Quarantine Insights Please note: The workbook has a total of 12 tabs. If all tabs are not visible, you can access the remaining tabs using the "..." located at the end of the tab list on the right side. New insights and visuals We have added new insights and visuals to help security team members better understand their Email security posture. Some examples: Detection Overview tab - Bad traffic percentage (%) - Inbound Emails Visualizes bad traffic (% of emails with threats) compared to total inbound emails over time summarizing the data daily. Email – Malware/Email-Phish detection tabs - Zero Day detections (URL & Attachment detonation) Visualizes total emails with Malware/Phish detections over time summarizing the data daily by detection technologies/controls used for detecting unknown-unique malware and phish (URL detonation, File detonation). Email - Phish Detections tab - Top Domains Outbound with Emails with Threats Inbound (Partner BEC) Visualizes top outbound recipient domains by outbound email volume and shows total number of inbound emails with Threats from the same domains (as inbound senders). Email – Malware/Phish/Spam Detection tabs - Detections by delivery location Visualizes total emails with Malware/Phish/Spam detections over time summarizing the data daily by Delivery Location. These insights can help security teams drive towards stronger security posture by adopting Quarantine as filter verdict action replacing Move to Junk email folder. URL Detections and Clicks tab – Top malicious URLs clicked by users Visualizes top malicious URLs with the number of clicks attempts performed by users. False Negative (FN) Submissions tab – new insights added for user defined filter verdict override configuration impacting the delivery action of the reported email, top 10 inbound P2 senders' domains of reported emails, top subjects of the internal emails reported by users as Phish, number if user reported Phish emails where the email is already in the Junk email folder. Updated Insights We have updated existing insights by adding additional information to them or visualizing the raw data in a different way. Some examples: Email – Malware/Phish/Spam Detection tabs - Email Top 10 Domains sending Malware table view now has Total emails sent by the sender domain and bad traffic % from the sender domain. Grid views are now searchable: False Negative (FN) Submissions/ False Positive (FP) Submissions are separated now on their own tab, existing insights got updated to understand better what users and security team members are submitting. Malware family related visuals on Email – Malware detections and File - Malware Detections (SharePoint, Teams and OneDrive) are using searchable grid now: How can I get the updated version? The latest version of the Microsoft Defender for Office 365 Detections and Insights workbook is available as part of the Microsoft Defender XDR solution in the Microsoft Sentinel - Content hub. Version 3.0.12 of the solution has the updated workbook template. If you already have the Microsoft Defender XDR solution deployed, version 3.0.12 is available now as an update. After you install the update, you will have the new workbook template available to use. If you install the Microsoft Defender XDR solution for the first time, you are deploying the latest version and will have the updated template ready to use. How to share the workbook with others Leveraging Microsoft Sentinel workbooks for reporting to leadership is a common use case. A common concern is granting recipients access to Microsoft Sentinel or all of the tables within the workspace. Using some different RBAC components, this can be done. For details, see the Manage Access to Microsoft Sentinel Workbooks with Lower Scoped RBAC on the Microsoft Sentinel Blog. Can I edit the workbook and change the visuals? Yes, absolutely. The Microsoft Defender for Office 365 Detections and Insights is a workbook template in Microsoft Sentinel. It is ready to use with a few simple clicks, however when needed you can save and edit the workbook based on your organization’s need. You can customize each visual easily or review the underlying KQL. Simply edit the workbook after saving, then adjust the underlying KQL query, change the type of the visual, or create new insights.
