The 2017 AP Moller-Maersk cyber-attack showed how vulnerable ports, shipping and terminals are in an age of cyber-reliance. NotPetya malware infected Maersk’s systems and shut down every laptop and mobile device connected to it within seven minutes.

The attack affected 76 ports, 800 vessels, tens of millions of tonnes of cargo and reportedly cost the company an estimated $300m.

It could have been an awful lot worse, but fortunately Maersk effectively managed and recovered from this malicious attack.
