Container Processing Halted at The Port of Nagoya

July 6, 2023


The Port of Nagoya, the largest and busiest port in Japan, has been targeted in a ransomware attack. The attack occurred around 6:30AM on July 4. A notice was issued reporting a malfunction in the “Nagoya Port Unified Terminal System” (NUTS), the central system controlling all container terminals in the port.

The attack held up shipments of Toyota auto parts containers for two days, but the port reopened Thursday morning.
All container loading and unloading operations at the terminals using trailers were canceled, causing massive financial losses to the port and severe disruption to the circulation of goods to and from Japan. LockBit 3.0 was confirmed as the attacker.

It took 3 days for the port to fully resume. A nearby Toyota auto parts packaging plant that exports through the port had to shutdown on Friday.
