  • Method and apparatus for detecting the occurrence of a ransomware attack on a storage volume
    Patent number: 12248573
    Abstract: A Ransomware Activity Detection System (RADS) characterizes historic read/write IO activity on a storage volume, and also characterizes historic data characteristics of the storage volume, such as the percentage reducibility of the data held in the storage volume. The RADS monitors the storage volume to identify differences between current read/write IO activity and historic read/write IO activity, as well as difference between current data characteristics of the storage volume and historic data characteristics of the storage volume. When the RADS detects a significant difference in read/write IO activity on a storage volume, that is coupled with a significant changes to the data characteristics of the storage volume, the RADS protects the storage volume and generates an alert of the possible occurrence of a ransomware attack. Protection may occur prior in connection with any bulk read operation to proactively protect storage volumes against ransomware attacks.
