Asahi Says More than 1.5 Million Customers' Data Potentially Leaked in Cyber-Attack
The ransomware attack disrupted operations and delayed earnings, exposing data of nearly 2 million including customers and employees, Asahi said on Nov 27.
- Asahi's November 27 update shows personal information linked to around 2 million customers and employees may have been leaked in a cyberattack.
- Investigators found the breach launched via compromised network equipment at a Group datacentre in Japan, and the intruders deployed an encryptor on multiple live servers and some connected PCs on September 29, 2025.
- According to Asahi's breakdown, 1.525 million customer service contacts, 114,000 external contacts, 107,000 current and former employees, and 168,000 family members had names, addresses, phones, and emails exposed, excluding credit card details.
- Operational outages forced manual order-taking and caused shop shortages, leading Asahi to delay its full-year earnings report for the period ending December 31 while aiming to resume orders and shipments in December with logistics normalisation by February.
- Ransomware group Qilin claimed responsibility on October 9, and Asahi says it spent nearly two months containing the attack with staged system restoration; CEO Atsushi Katsuki said, 'Even if we had a ransom demand, we would not have paid it'.
