A cyberattack on a food and logistics firm disrupts the supply of frozen food to thousands of clients, including major franchises like Kentucky Fried Chicken.

July 23, 2026

Nichirei, a Japan-based frozen-food supplier and logistics firm, has largely recovered after a cyberattack disrupted its operations last week, resulting in curtailed shipments and leading Kentucky Fried Chicken franchises in the country to warn of shortages.

Russia-linked ransomware group RansomHouse reportedly claimed credit for the breach earlier this week, posting some Nichirei data to the Dark Web. Nichirei acknowledged the breach but has only provided limited details on the actual events, which impacted its logistics and shipping operations.
