Hackers to target global supply chain?

US Coast Guard Rear Admiral John Mauger has warned that cyber warfare is the biggest threat to maritime transport. According to Mauger, the world is struggling to keep up with demand for goods. While this includes scarcity of goods, it also includes the speed at which goods can be moved. Ports are understaffed and overcrowded, with ships waiting to be allowed to dock. Mauger says that a cyberattack on this already strained system could mean huge problems for almost every industry. Large shipping providers, such as Maersk, have already been the target of ransomware, and Mauger believes it is a matter of time before attackers try again.
