On July 4th, 2023, Japan’s largest and busiest trading port, the port of Nagoya, was hit with a ransomware attack. The attacker is suspected to be a Russian-based adversary, with the Nagoya Harbor Transportation Association attributing the attack to the LockBit ransomware group. On July 5th, the port’s administrative authority raised awareness of a malfunction that had propagated in the Nagoya Port Unified Terminal System (NUTS), the central system controlling all five (5) cargo container terminals in the port. The port authority is currently working to repair the NUTS system, but until then, all loading and unloading of containers using trailers has been halted. Significant financial losses have been and will continue to be incurred until the NUTS system is repaired, along with severe disruptions to the circulation of goods to and from Japan. The port of Nagoya makes up around 10% of Japan’s total trade volume. It operates twenty-one (21) piers and 290 berths, handling over two million containers a year with an estimated cargo tonnage of around 165 million. Toyota Motor Corporation, one of the world’s largest automaker manufacturers, also uses the port to export most of its cars. The port of Nagoya has seen ransomware attacks before but none to the severity of this one.
