The most challenging latest major disaster was the Cyber Breach in MAERSK during 2017. At the end of June 2017 MAERSK was subject of a cyber attack which caused major problems to operations and terminals worldwide. A computer virus, called GoldenEye or Petya, began its spread on Tuesday 27th June 17 in Ukraine and affected companies in dozens of countries. The virus entered into system as an employ answered an unidentified mail by clicking. Several port terminals run by a Maersk division, including in the United States, India, Spain, the Netherlands, were struggling to revert to normal operations after experiencing massive disruptions. Dry cargo could not be delivered and no container would be received. Several IT systems were shut down and MAERSK paid almost $300m as cost of operations suspension and cargo damages. Cost of systems upgrading and additional protected measures cannot be calculated yet. What was the reaction of the Company?
