OCIA assesses that if specific industrial control systems (ICS) were successfully infected with ransomware, it could affect the ability of certain sectors to provide real-time management and control of large networks of geographically scattered equipment. Although security researchers have demonstrated the possibility of ransomware targeting control systems, OCIA assesses that such an attack is highly unlikely given the higher success rate against consumer and business systems, the likelihood that business and process control networks are segmented, and the ability for operators to take a control system out of service and employ manual overrides.
