What it detects

This rule flags process creation where schtasks.exe is used with a /create command and the action references suspicious folder paths such as C:\ProgramData\ or %ProgramData%. Attackers often use scheduled tasks for persistence by placing commands in commonly abused locations and invoking them via command-line tooling. It relies on Windows process creation telemetry, matching schtasks.exe invocations and the presence of /create along with PowerShell/cmd command patterns and suspicious folder strings within the CommandLine.
