Abstract
A network connected storage device detects unusual file-sharing-command activity based on a baseline file-sharing-command signature and analyzes files stored on the storage with respect to a parameter, such as entropy, to determine whether ransomware may have infiltrated the storage device, or a storage associated therewith. Applying by the storage device a function to an entropy value corresponding to a second portion of a file may result in a determination that an analyzed entropy corresponding to the second portion may have been partially encrypted by ransomware. The analyzed entropy corresponding to the second file portion may be compared to an entropy of a first file portion. The first file portion may be a different portion of the same file as the second portion or may be the same portion of the same file that resulted from analysis before the triggering event.
