What it detects

This rule identifies creation of files under typical rclone configuration locations on Windows, specifically paths containing '\.config\rclone\' within a user profile directory. Creating rclone config files can be used to stage access credentials and endpoints for file transfer and potential exfiltration. It relies on Windows file event telemetry that records the target file path for the creation event.
