Nichirei Co confirms cyberattack disrupting refrigerated warehouse and frozen food logistics, impacting customers including KFC Japan

KFC warned of delivery delays leading to possible menu restrictions, shortened hours, or temporary suspension of online orders

No data leaks or attacker claims have surfaced; disruptions suggest ransomware, but both companies expect operations to normalize by week’s end

Nichirei Co, a large Japanese company which produces frozen and processed foods, and operates cold-chain logistics to distribute them across the country, has confirmed it suffered a cyberattack which affected some of its customers, including KFC.

The company confirmed the news in a notice stating, “Today, Nichirei Co experienced a system failure caused by unauthorized access."

Nichirei said that it is currently investigating the incident, but that there is no evidence of personal or customer data leaking outside the company. However, due to the nature of the incident (which hasn’t been explained in detail), multiple operations have been affected, including refrigerated warehouse inbound/outbound operations, and frozen food shipping services.

No claims yet

These disruptions affected, among others, KFC - one of the largest fast food chains in the world. In a separate announcement, KFC said that a system failure at Nichirei Logistics Group, which happened on July 13, affected the company’s logistics and delivery sites. “From Tuesday, July 14, 2026, food delivery to KFC stores is expected to be affected,” it said.

“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.”

The nature of the attack, or the identity of the attackers, were not disclosed. Since Nichirei had to shut down some of its services, it could mean this was a ransomware attack and that some company data was stolen after all. The Register reports that KFC Japan hasn’t posted information about store closures and continues to promote summer menu items.

At press time, no threat actors claimed responsibility for the attacks, and no Nichirei/KFC data surfaced on the dark web. The companies expect to resume normal operations by the end of the week.
