DNV said today it is still working to ensure its ShipManager software’s servers can be put back online as soon as possible after the cyber-attack which affected 1,000 vessels operated by 70 customers.

The major class society ShipManager software was the victim of a ransomware cyber-attack on the evening of Saturday 7 January which led to it taking the servers offline.

Users can still use the onboard, offline functionalities of the ShipManager software and DNV said there are no indications that any other software, data or services have been affected.
