A coalition of shipping industry associations has published The Guidelines on Cyber Security Onboard Ships, laying out best practices for the giant ships that ply the seas, and revealing that these behemoths are routinely infected with worms, ransomware, and malware spread by infected USB devices. The document recounts incidents in which infected ships were stranded because malware caused their computerized navigation to fail, and there were no paper charts to fall back on; incidents where fleet owners paid off ransomware demands to keep ships at sea safe, and where the entire digital infrastructure of a ship at sea failed due to malware that spread thanks to weak passwords. The report includes details of two incidents where USB thumb drives have led to a cyber-security incident, delays, and financial damage. 1) A dry bulk ship in port had just completed bunkering operations.
