In January 2023, Oslo-based DNV—a leading global maritime classification society and risk management provider—fell victim to a ransomware attack on January 7. The cyberattack forced the company to shut down IT servers linked to its ShipManager system, a critical platform used for vessel operations and fleet management. The incident disrupted services for 70 affected customers, impacting around 1,000 vessels worldwide. DNV engaged in daily communications with clients to provide updates on forensic investigations, though the full extent of data compromise or operational downtime was not immediately disclosed. The attack highlighted vulnerabilities in maritime cybersecurity, raising concerns over potential cascading effects on global shipping logistics, safety compliance, and customer trust. While no direct evidence of data theft was confirmed in the initial reports, the operational outage and reliance on manual workarounds posed significant risks to DNV’s reputation and financial stability, given its role in certifying vessel safety and regulatory compliance.
