In a statement on the Danish shipowners' website entitled “Maersk IT systems are down”, it said: “We can confirm that Maersk IT systems are down across multiple sites and business units due to a cyber attack. We continue to assess the situation,” MANA correspondent reported.
“The safety of our employees, our operations and customer's business is our top priority.”
The website of its core container line business Maersk Line was down completely apart from a similar message which also apologised for any inconveniece to customers. The website of APM Terminals was also down displaying an internal error message.
It is unclear what the wider impact on the group's business operations is at this stage.
The BBC was reporting a global ransomware attack, similar to last month's Wannacry Attack, causing chaos to companies worldwide.
Maersk Line launched a major push to digitise its containers shipping business and customer experience last year.
