What it detects

This rule flags Windows process creation where the command line contains all of the following: "schtasks", "create", "wscript", and " /e:vbscript". Such activity is commonly used to establish persistence by creating scheduled tasks that execute VBScript through Windows Script Host. It relies on process creation telemetry, specifically the full command line of spawned processes, to match the expected parameter combination.
