Japanese beer giant Asahi confirmed Thursday that hackers stole personal information from roughly 2 million people during a September ransomware attack. The Qilin ransomware group targeted 1.5 million customer service contacts, stealing names, addresses, phone numbers, and emails. Another 107,000 employees had similar data plus birthdates and gender information compromised, while 168,000 employee family members also had personal details stolen.

The attack disrupted Asahi's operations across Japan, with systems still being gradually restored. Hackers infiltrated network equipment to access the data center, then deployed ransomware across multiple servers. CEO Atsushi Katsuki said full system restoration could take until February, though product shipments are resuming in stages.
