Abstract: In some examples, a system provides access, to a first server, a copy of a volume of data associated with a second server, where the first server is protected against unauthorized access. The first server receives first signatures generated by an agent in the second server based on applying a function on data objects of the volume. The first server generates, at the, second signatures derived based on applying the function on data objects of the copy of the volume. The first server determines whether malware that performs unauthorized data encryption of data of the second server is present, based on comparing the second signatures to the first signatures.
