Japanese Brewer Hit in Ransomware Attack

A major global brewer based in Japan reverted to some manual operations after a ransomware attack hit the company last week. The attack forced it to suspend some of its operations like beer production. “Asahi Group Holdings, Ltd. is currently experiencing a system failure caused by a cyberattack, affecting operations in Japan,” the company said. It suspended the following operations: order and shipment operations at group companies in Japan and call center operations, including customer service desks. All 30 Asahi plants in Japan were forced to temporarily halt operations and beer production reportedly resumed at the six plants on October 2. Asahi Breweries did not specify how much longer it would take to return to full capacity.

Estimated Cost

Estimates are over $100 million: Nationwide suspension of automated order processing and logistics; production halt at many domestic plants; manual processes deployed; phased restoration from early October 2025
