What it detects

This rule detects rclone copying local data to a MEGA cloud remote, a double-extortion staging and exfiltration step. This behavior was observed during Crux ransomware intrusions prior to encryption. Cloud syncing of internal files to attacker-controlled storage indicates active data theft.
