Abstract
A computer program product, system, and method for generating coded fragments comprises initializing historical I/O activity data structures and recent I/O activity data structures associated with a logical unit (LU) of storage; receiving an I/O request from a host, the I/O request associated with one or more chunks within the LU; adding metadata about the I/O request to the recent I/O activity data structures; generating a ransomware probability by comparing the recent I/O activity data structures to the historical I/O activity data structures; and if the ransomware probability exceeds a first threshold value, taking one or more first actions to mitigate the effects of ransomware within the host.
