May 28, 2022


Several Greek shipping companies fell victim to a cyber attack on Halloween over the weekend, resulting in the loss of important files. The companies affected used the communication systems of Danaos Management Consultants and came in direct contact with the company. Reportedly, the cyber attack blocked their communication with ships, suppliers, agents, charterers and supplies, while at the same time the files with their correspondence were lost.

Danaos Management Consultants sent instructions to its customers, asking them among other things to back up critical files to external hard drives. Danaos is among the oldest maritime IT companies and could face litigation.
