Real-time monitoring identifies a process performing rapid, bulk deletion or overwrite of files across multiple Industrial Control System (ICS)-relevant directories within a short time window, by a process not associated with documented data retention management, correlated with a system crash shortly after. Documented in CaddyWiper, deployed via GPO alongside Industroyer2. OT operational-fidelity gate: Alert only when the action is not attributable to an authorized operator/engineering source for the specific target and function, and it is either outside an approved change/maintenance window or lacks matching change-control context; where telemetry permits, require corroborating device, configuration, or process-state effect. Suppress activity that fully matches approved maintenance, commissioning, failover, recovery, or tested control procedures.
