Japan's food supply chain is currently grappling with the aftermath of a cyberattack targeting **Nichirei Logistics Group**, a critical player in the country's cold storage and distribution network. The company, responsible for transporting frozen and refrigerated goods for approximately 5,000 customers, confirmed on Thursday that its servers had been breached. ### Systems Down to Contain Breach The attack prompted **Nichirei Logistics Group** to disconnect key systems, effectively bringing parts of its extensive logistics network to a halt. This drastic measure was taken to contain the breach and safeguard customer data. While the company anticipates a gradual restoration of operations beginning Friday, a full return to normal service remains uncertain. ### Data Implications and Regulatory Notification During its ongoing investigation, **Nichirei** discovered that some affected servers contained personal information. The company has proactively notified Japan's data protection authorities and has committed to promptly reporting any confirmed data leakage. Technical details regarding the attack, including the identity of the perpetrators or whether ransomware was involved, are being withheld to mitigate further security risks. ### Widespread Impact on Food Establishments The ripple effects of the outage are being felt acutely by businesses reliant on **Nichirei**'s network of 140 refrigerated distribution centers. **KFC Japan** reported significant disruptions to ingredient deliveries, including its iconic Original Recipe chicken, affecting all of its more than 1,300 restaurants. The fast-food giant warned of potential ingredient shortages, limited menus, reduced operating hours, and even temporary store closures. Online ordering through **KFC Japan**'s website and mobile app has also been temporarily suspended, with no clear timeline for resumption. ### Broader Industry Disruptions Beyond **KFC**, numerous other major Japanese restaurant operators, retailers, and food manufacturers have reported delivery delays and product shortages. Affected entities include bento chain **Hotto Motto**, restaurant operator **Yayoi Ken**, and conveyor-belt sushi chain **Kura Sushi**. Retail giant **Aeon** confirmed product shortages in some of its supermarkets, while frozen food manufacturer **TableMark** has been unable to ship products to its customers. This incident follows a recent spate of cyberattacks disclosed by several major Japanese companies across various sectors, including telecommunications provider **KDDI**, insurer **Aflac** (Japanese unit), electronics manufacturer **Nidec**, and brewer **Sapporo Holdings**. However, there is currently no indication of a link between these separate incidents.
