Abstract
A system for detecting by a cloud service a ransomware attack on a client device is provided. The system monitors changes to files of the client device that are stored by the cloud service. The system assesses whether a change to a file appears to be malicious in that the change may be caused by ransomware. When the change to the file appears to be malicious, the system performs a countermeasure to prevent synchronization of files of the client device with other client devices and with the cloud service to prevent the propagating of files from the client device, which is undergoing a ransomware attack.
