What it detects

This rule detects the Rclone data-transfer utility executing under a renamed file name. ALPHA SPIDER renamed rclone to svchost.exe and to a misspelled cloud-software name to blend exfiltration traffic with normal activity. A process whose original file name is rclone but whose on-disk name differs indicates masquerading for exfiltration.
