KFC Japan warns cyberattack could disrupt stores

A cyberattack on Nichirei Co is disrupting cold-chain logistics in Japan and could force some KFC Japan stores to limit menus, shorten hours, or temporarily suspend operations.

Nichirei, a major Japanese producer of frozen and processed foods that also runs refrigerated logistics services, said it suffered a system failure caused by unauthorized access. In its notice, the company said it is still investigating and has found no evidence that personal or customer data leaked outside the business.

The operational impact is already clear. Nichirei said the incident affected refrigerated warehouse inbound and outbound operations as well as frozen food shipping services, creating knock-on problems for customers including KFC.

KFC said the failure at Nichirei Logistics Group occurred on July 13 and would affect food deliveries to stores from Tuesday, July 14, 2026.

“As a result, each store may suspend operations depending on some products going out of stock, menu restrictions, shortened business hours, or ingredient stock availability. Additionally, online orders from the official app and website have also been temporarily suspended.”

Neither company disclosed the nature of the attack or identified any attackers. TechRadar notes that the service shutdowns could point to ransomware, but at press time no threat actor had claimed responsibility and no Nichirei or KFC data had appeared on the dark web.

According to The Register, KFC Japan had not posted information about store closures and was still promoting summer menu items. Both companies said they expect normal operations to resume by the end of the week.
