Asahi Group Holdings, Japan’s largest beer producer, has experienced a significant data breach impacting approximately 1.9 million individuals. The incident, initially disclosed on September 29, 2025, stemmed from a ransomware attack that compromised customer data. Qilin ransomware claimed responsibility, publishing samples of exfiltrated files on a data leak site. The compromised data included full names, genders, physical addresses, phone numbers, and email addresses. The scope of the breach encompasses several categories of individuals. Approximately 1,525,000 customers who engaged with Asahi’s customer service centers (across its breweries, drinks, and foods divisions) were affected. An additional 114,000 individuals comprised external contacts receiving congratulatory or condolence telegrams from the company. Furthermore, 107,000 current and retired employees, along with 168,000 family members of those employees, were also affected. The specific data exposed varied across these categories; for the customer segment, this encompassed name, gender, physical address, and email address, while employee records included dates of birth and gender. Crucially, the company asserts that no payment card information was accessed during the breach. Following the incident, Asahi established a dedicated contact line to assist affected individuals with information regarding the exposed personal data. The CEO, Atsushi Katsuki, indicated that full system restoration is ongoing, two months after the initial compromise, and that product shipments are resuming in phases tied to the progress of system recovery. To mitigate further risks, Asahi is implementing a series of preventative measures, including redesigned communication routes, tightened network controls, restrictions on external internet connections, upgrades to threat detection systems, security audits, and revised backup and business continuity plans. The company is focused on proactively improving its information security posture across the Group through enhanced protocols and safeguards. |
