Cyberattack on Nichirei Logistics Group Disrupts Frozen Food Deliveries to KFC Japan and Thousands of Restaurants Nationwide

A cyberattack targeting Nichirei Logistics Group, Japan's largest operator of refrigerated and frozen logistics, quickly moved beyond computer systems and reached restaurant kitchens across the country. The incident disrupted deliveries to approximately 5,000 clients and caused immediate shortages of essential ingredients, most notably chicken for KFC Japan.

Nichirei Logistics Group reported a major system failure on July 13. Investigators later determined that attackers had gained access to the company's servers. To contain the intrusion and protect client information, Nichirei disconnected key systems, effectively halting large portions of its logistics network that relies on 140 refrigerated distribution centers.

The shutdown prevented normal warehouse operations and the dispatch of frozen and chilled products. During the investigation, the company discovered that personal data was stored on some of the affected servers. Nichirei notified Japan's data protection authority and stated it would publicly disclose any confirmed data theft once the review is complete.

The company has not revealed the identity of the attackers, the method used to breach its systems, or whether ransomware was deployed, citing security concerns. Technical details of the incident have also been withheld.

Clients dependent on Nichirei's infrastructure felt the effects almost immediately. KFC Japan confirmed that supplies to all of its more than 1,300 restaurants were disrupted, including chicken required for its signature Original Recipe. Some locations may reduce menu options or operating hours, and temporary closures remain possible if stocks run out. The chain also suspended online and mobile app orders because timely deliveries could not be guaranteed.

Other major operators reported similar problems. The ready-meal chain Hotto Motto, restaurant operator Yayoi Ken, and sushi chain Kura Sushi all experienced delivery interruptions. Supermarket chain Aeon faced product shortages in some stores, while frozen-food manufacturer TableMark was unable to ship goods to retail and corporate customers.

Nichirei expects to begin phased restoration of services on July 17, although no timeline has been provided for a complete return to normal operations.
