Best practices and the latest news on Microsoft FastTrack, The employee experience platform to help people thrive at work, Expand your Azure partner-to-partner network, Bringing IT Pros together through In-Person & Virtual events. The purpose of this cheat sheet is to cover commonly used threat hunting queries that can be used with Microsoft Threat Protection. Otherwise, register and sign in. For detailed information about the events types (ActionType values) supported by a table, use the built-in schema reference available in Microsoft 365 Defender. While constructing queries, use the built-in schema reference to quickly get the following information about each table in the schema: To quickly access the schema reference, select the View reference action next to the table name in the schema representation. SHA-256 of the file that the recorded action was applied to. 'Isolate', 'CollectInvestigationPackage', ), The person that requested the machine action, The comment associated to the machine action, The status of the machine action (e.g., 'InProgress'), The ID of the machine on which the action has been performed, The UTC time at which the action has been requested, The last UTC time at which the action has been updated, A single command in Live Response machine action entity, The status of the command execution (e.g., 'Completed'). Use the query name as the title, separating each word with a hyphen (-), e.g. Through advanced hunting we can gather additional information. The number of available investigations by this query, A link to get the next results in case there are more results than requested, The number of available machine actions by this query, The index of the live response command to get the results download URI for, The identifier of the investigation to retrieve, The identifier of the machine action to retrieve, A comment to associate to the investigation, Type of the isolation. Match the time filters in your query with the lookback duration. You can move your advanced hunting workflows from Microsoft Defender for Endpoint to Microsoft 365 Defender by following the steps in Migrate advanced hunting queries from Microsoft Defender for Endpoint. Once this activity is found on any machine, that machine should be automatically isolated from the network to suppress future exfiltration activity.

I'd like to share some of the work we've recently completed for advanced hunting on Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP). For detailed information about various usage parameters, read about advanced hunting quotas and usage parameters. While the old table names are in use, these new table names are already functional (i.e., both sets of names are currently supported). You can proactively inspect events in your network to locate threat indicators and entities. Let us know if you run into any problems or share your suggestions by sending email to wdatpqueriesfeedback@microsoft.com. To make sure you are creating detections that trigger true alerts, take time to review your existing custom detections by following the steps in Manage existing custom detection rules. I've applied the August 2020 update to my domain controllers, and now I need to watch for event ID 5829 in the system log. We also have some changes to the schemachanges that will allow advanced hunting to scale and accommodate even more events and information types. We can use some inspiration and guidance, especially when just starting to learn a new programming or query language. Selects which properties to include in the response, defaults to all.
