Maersk could take multi-million-pound hit following the disruption caused by a global cyber attack last week, according to experts.

The news comes as the Danish shipping giant, which handles one in seven containers shipped worldwide, said yesterday it has restored its major applications after bringing its IT systems back online.

According to Lars Jensen, CEO and partner at SeaIntelligence Consulting, Maersk books an average revenue of $2.9m. In the 150 hours that Maersk’s systems were down, $435m (£347m) worth of revenues couuld be affected.

Maersk’s client-facing operations returned to normal yesterday after container deliveries resumed at its major ports. Maersk’s subsidiary APM Terminals at the Port of New York and New Jersey were closed for two days last week 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 was down last week.

A Maersk spokesperson told City A.M. that the shipping giant cannot reveal the cost of the cyber attack until “a proper business impact assessment has been made”.

“We are still very much focused on getting our systems back up to full functionality to support our customers,” he said.
