The Port of Nagoya, the largest and busiest port in Japan, has been targeted in a ransomware attack that currently impacts the operation of container terminals.

Today, the administrative authority of the Port of Nagoya has issued a notice about a malfunction in the “Nagoya Port Unified Terminal System” – the central system controlling all container terminals in the port.

“Upon investigating the cause, we held a meeting with the Nagoya Port Operation Association Terminal Committee, who operates the system, and the Aichi Prefectural Police Headquarters [and] it was discovered that the issue was a ransomware infection” – Nagoya Port.

All container loading and unloading operations at the terminals using trailers have been canceled, causing massive financial losses to the port and severe disruption to the circulation of goods to and from Japan.

On September 6, 2022, the website of the port was unreachable for about 40 minutes due to a massive distributed denial-of-service attack launched by the pro-Russian group Killnet.

At the time of publishing the threat actor behind the ransomware attack on the Port of Nagoya remains unknown as no threat actor has claimed the intrusion publicly, yet.
