Abstract: In general, one or more embodiments of the invention relates to systems and methods for detecting ransomware attacks earlier and closer to the time of attack. The ransomware attack can be detect by determining a change rate of data blocks between snapshots. The ransomware attack can also be detected by determining the pattern of changes in the blocks deviates from a normal pattern. By making these determinations, a quick identification of possible ransomware attacks can be made and other methods of mitigating the attack can be deployed when they are may still be useful to mitigate potential damage to a user's data.
