Some 1,000 vessels have been affected by a cyberattack on DNV’s vessel operations and management software, the classification society has confirmed.

DNV said it shut down ShipManager’s IT servers in response to a ransomware attack that affected the software on January 7. The marine fleet management solution supports the management of vessels and fleets in technical, operational and compliance aspects, including maintenance and repair, procurement, security systems and data analysis.

The software’s embedded and offline functionalities remain available to the 70 affected customers as DNV works with global IT security partners to investigate the incident and restore online operations, the group said.

There is no indication that any other DNV software or data was affected, and the server outage does not affect any other DNV services, the classification society added.

DNV said it is in dialogue with Norwegian police about the incident and is in contact with affected customers to update them on the findings of ongoing forensic investigations.
