What it detects

This rule detects execution of a binary named avastrclone.exe, the renamed rclone client The Gentlemen operators disguise as an Avast component to blend in while exfiltrating data over cloud storage. The masqueraded name combines a legitimate-looking brand with an untrusted tool. Detecting it exposes covert bulk exfiltration.
