Shipping giants could lose millions of dollars following the disruption caused by a global cyber attack this week, according to tech experts.
Lars Jensen, CEO and partner at SeaIntelligence Consulting, estimated that Danish shipping giant Maersk could have lost up to $60m (£46m) in less than a day after the cyber attack named “Petya” hit its IT systems.
Maersk, which handles one in seven containers shipped worldwide, said the attack led to congestion at its subsidiary APM Terminals which operates in ports in the US, India, Spain and the Netherlands.
The APM Terminals at the Port of New York and New Jersey were closed yesterday because of the attack.
Meanwhile, operations at one of three terminals at India's largest container port JNPT in Mumbai, which is also operated by Maersk, was hit by the ransomware attack.
One of the two big container terminals run by Maersk at the port in Barcelona was also affected while another at the Spanish port of Algeciras has been down since Tuesday.
Jensen said that the attack could have a “huge impact” on Maersk’s business depending on how long it takes to get all systems up and running.
Jensen said: “This does not mean that Maersk has lost this level of business, as likely a number of customers will simply postpone their bookings a little while - but the keyword is "a little while".
“The longer the outage lasts, the more of these customers will start to shift their cargo volumes to other carriers. Time is therefore of the essence in terms of getting systems restored following a cyber attack.”
Maersk declined to comment on the figures.
In a statement yesterday, it said: "The aggregate impact on our business is being assessed."
