We are continually building up documentation about advanced hunting and its data schema. It does not send all the raw ETW events to the backend (as that would actually be something totally different and may overload endpoints). Each of these action types include relevant contextual information, such as: Please keep in mind these events are available only for RS6 machines. We've added some exciting new events as well as new options for automated response actions based on your custom detections.

This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. These rules let you proactively monitor various events and system states, including suspected breach activity and misconfigured endpoints. Watch this short video to learn some handy Kusto query language basics. Hunting queries for Microsoft 365 Defender will provide value to both Microsoft 365 Defender and Microsoft Sentinel products, hence a multiple impact for a single contribution. Each table name links to a page describing the column names for that table. A tag already exists with the provided branch name. But this needs another agent and is not meant to be used for clients/endpoints TBH.

Some information relates to prereleased product which may be substantially modified before it's commercially released. This option automatically prevents machines with alerts from connecting to the network. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. If I try to wrap abuse_domain in tostring, it's "Scalar value expected". Running the query on advanced huntingCreate a custom detection rule from the queryIf you ran the query successfully, create a new detection rule. For best results, we recommend using the FileProfile() function with SHA1.
