What it detects

This rule detects rclone-style command lines that reference a config file and copy data to a remote destination, matching the Sinobi exfiltration step. The actors ran rclone with a custom config to copy victim data to attacker-controlled cloud storage before encryption. Bulk copy to a remote target via rclone flags is a common precursor to double-extortion ransomware.
