The U.S. Coast Guard last month issued a safety bulletin following a ransomware attack that impaired both the IT systems and industrial control systems of a facility regulated by the Maritime Transportation Security Act (MTSA), and prompted a 30-hour operational shutdown. The ransomware program, identified as Ryuk, was delivered via a phishing email containing a malicious link that was clicked by an employee. According to the alert, the ransomware encrypted critical network files, then “further burrowed into the industrial control systems that monitor and control cargo transfer and encrypted files critical to process operations.”
