Windows Defender Advanced Threat Protection (ATP) is a unified platform designed to help enterprise networks prevent, detect, investigate, and respond to advanced threats. In our first example, well use a table called ProcessCreationEvents and see what we can learn from there. Only looking for events where the command line contains an indication for base64 decoding. Watch this short video to learn some handy Kusto query language basics. // Find all machines running a given Powersehll cmdlet. Image 10: Example query that returns the last 5 rows of ProcessCreationEvents where FileName was powershell.exe or cmd.exe, note this time we are using == which makes it case sensitive and where the outcome is filtered to show you EventTime, ComputerName and ProcessCommandLine. Sample queries for Advanced hunting in Microsoft 365 Defender. The following reference - Data Schema, lists all the tables in the schema. Case-sensitive for speedCase-sensitive searches are more specific and generally more performant. There may be scenarios when you want to keep track of how many times a specific event happened on an endpoint. Find rows that match a predicate across a set of tables.
