RANSOMWARE DETECTION AND INTELLIGENT RESTORE

This application relates to ransomware detection and intelligent restore. Ransomware typically involves an I/O heavy process of encrypting data files and/or deleting or renaming the original files. Thus, ransomware attacks may be detected by analyzing the I/O activity in a given file system. When a potential ransomware attack is detected, a timestamp is recorded. If the client machine is indeed taken over by the ransomware attack, an intelligent restore operation can be performed such that the file system is automatically restored to a point in time prior to the infection by the ransomware attack using the recorded timestamp.
