Ransomware attack on maritime software impacts 1,000 ships

About 1,000 vessels have been affected by a ransomware attack against a major software supplier for ships. Oslo-based DNV – one of the world’s largest maritime organizations – said it was hit with ransomware on the evening of January 7 and was forced to shut down the IT servers connected to their ShipManager system. “DNV is communicating daily with all 70 affected customers to update them on findings of the ongoing forensic investigations. In total around 1000 vessels are affected,” DNV said in a statement on Monday. “All users can still use the onboard, offline functionalities of the ShipManager software. There are no indications that any other software or data by DNV is affected. The server outage does not impact any other DNV services.” DNV said it is working with Norwegian police and IT security companies to respond to the incident. DNV is the world’s largest classification society – an organization that manages the technical certifications for the construction and operation of ships and offshore structures. More than 13,175 vessels and mobile offshore units are currently serviced by DNV – which brought in over $2 billion in revenue in 2021. The attack on DNV is the latest affecting the shipping industry. Two weeks ago, the Port of Lisbon was targeted by the LockBit ransomware group and Europe saw a string of ransomware attacks on ports throughout 2022.
