This digest was compiled by AI from multiple sources — links to the originals are below.
Nichirei, a Japanese frozen-food supplier and logistics firm, suffered a ransomware attack last week that disrupted shipments to about 5,000 customers, including Kentucky Fried Chicken franchises in Japan. The Russia-linked RansomHouse group claimed responsibility, posting some of Nichirei's data on the Dark Web. The company said all locations are scheduled to return to normal operations within this week.
Attack Details
Nichirei acknowledged the breach on July 22 but provided limited details. The attack impacted its logistics and shipping operations, forcing the company to implement security measures with an external firm. RansomHouse posted some stolen data to the Dark Web earlier this week.
Supply Chain Impact
The attack affected about 5,000 customers, including KFC Japan, which warned of possible reduced hours at its franchises. Nichirei operates a fleet of 7,000 refrigerated vehicles from 141 logistics centers. The incident highlights vulnerabilities in tightly knit supply chains, according to Collin Hogue-Spears of Black Duck.
Ransomware in Japan
Nearly half of Japanese companies (46%) have suffered a ransomware attack, per a JIPDEC survey. The National Police Agency recorded 226 ransomware damage reports in 2025. In October 2025, Asahi suffered a similar attack that disrupted beer shipments for two weeks and required until February 2026 to fully recover.
What's Next
Nichirei expects all operations to return to normal within this week. It remains unclear whether the company paid a ransom or how the attackers gained access.
