The FBI and Coast Guard boarded oil tankers since the navigation and propulsion systems were breached by hackers.They were able to take back control of the ship’s navigation and propulsion systems. The FBI and Coast Guard assured the crew were not harmed in any way by the cyberattack, and the vessel is now safe. This is one of several recent cyberattacks, which also included a hack on Stryker medical device manufacturer, the LA public transit system, and over a hundred water facilities across the United States. How can oil tankers be protected from cyberattack while making sure that they can communicate with the outside world and other ships?
