A recently granted patent (Publication Number: US11930042B2) outlines a method for detecting and recovering from ransomware attacks within a cloud-based global file system. The process involves detecting a ransomware attack using a filer- or cloud-based detector that scores a set of markers indicating the attack. Upon detection, access to the affected volume is restricted, a recovery filer is activated, and a restore operation is initiated. Once the restore operation is completed, a new clean snapshot of the volume is created, and access is re-enabled. The method includes various tests such as tracking file creations, overwrites, and reads, as well as examining filenames and searching for ransom demands to detect ransomware attacks effectively.

Furthermore, the patent details the recovery process, emphasizing that the restoration from a ransomware attack is specific to the affected volume within the cloud-based global file system. The method ensures that recovery occurs within minutes from the point-in-time when the attack is detected, highlighting the efficiency and timeliness of the recovery process. By implementing machine learning and utilizing distinct markers with associated scores, the method aims to provide a comprehensive and proactive approach to ransomware detection and recovery in cloud environments.
