US Patent 10516688 Ransomware resilient cloud services

An anti-ransomware system protects data in cloud storage of a cloud services provider against a ransomware attack. A backup handler is configured to at least one of: selectively retrieve backup data generated by the cloud services provider from the cloud storage; and selectively generate backup data based on the data in the cloud storage and output the backup data to a storage device. A ransomware detector is configured to detect data changes to the data resulting from a ransomware attack. A ransomware remediator communicates with the ransomware detector and the backup handler and is configured to restore the data to a state prior to the ransomware attack based upon the backup data.
