rclone copy or sync to remote storage (T1567.002)

SIGmediumconfidence 70/100generated 2026-10-18

rclone.exe copying or syncing data to a remote — the exfiltration tool of choice for data-theft extortion crews. Observed for: APT27, APT31, APT40, BRONZE STARLIGHT, Chimera, Confucius and 17 more.

False positives
Matches only rclone running copy/sync; listing, config and mount do not match. Renamed rclone binaries are not covered by the Cortex/QRadar versions (Sigma also checks the PE description).

How to deploy on Sigma

  1. 1.Convert for your SIEM with sigma-cli / pySigma, e.g. sigma convert -t splunk -p sysmon rule.yml.
  2. 2.Run it as a hunt first: every rule ships as status experimental.
  3. 3.Promote to an alert once a week of results is clean on your data.

Check · The processing pipeline must map the logsource (firewall, dns, proxy, webserver, process_creation) to your field names.
