Abstract
In some examples, a storage system intercepts a write request communicated over a network from a requester in a host system, the write request to write data of a data volume. The storage system determines whether the data of the write request matches a specified pattern. In response to determining that the data of the write request does not match the specified pattern, the storage system indicates that the write request from the requester in the host system has been corrupted by malware that has performed an unauthorized encryption on the data.
