Asahi Group Confirms Ransomware Attack Disrupting Operations and Leaking Data

 

Japanese food and beverage conglomerate Asahi Group Holdings has confirmed that a ransomware attack severely disrupted its operations and potentially exposed sensitive data, including employee and financial information. The cyberattack, which occurred on September 29, 2025, forced the company to delay releasing its January–September financial results, originally scheduled for November 12. 

The attack paralyzed Asahi’s domestic order and shipment systems, halting automated operations across Japan. Despite the disruption, the company implemented manual order processing and resumed partial shipments to ensure a continued supply of its popular beverages and food products. 

The Qilin ransomware group has claimed responsibility for the breach, asserting that it stole over 9,300 files containing personal and financial data. On October 8, Asahi confirmed that some of the stolen data was found online, prompting a detailed investigation into the scope and type of compromised information. In a public statement, the company said it is working to identify affected individuals and will issue notifications once the investigation confirms unauthorized data transfer.  

Although the incident primarily impacted systems within Japan, Asahi stated there is no evidence of compromise affecting its global operations. 

Recovery efforts are steadily progressing. Asahi Breweries resumed production at all six of its factories by October 2, restoring shipments of Asahi Super Dry, with other product lines following soon after. Asahi Soft Drinks restarted production at six of its seven plants by October 8, while Asahi Group Foods has also resumed partial operations at all seven domestic facilities.  

However, Asahi’s systems have not yet been fully restored, and the company has not provided a definite recovery timeline. The ongoing disruption has delayed access to critical accounting systems, forcing a postponement of quarterly financial reporting. 

In its official statement, Asahi explained that the financial disclosure delay is necessary to ensure accuracy and compliance amid system recovery. The company issued an apology to shareholders and stakeholders for the inconvenience caused and promised transparent updates as investigations and remediation progress. 

The Asahi Group cyberattack serves as another reminder of the rising frequency and impact of ransomware incidents targeting major corporations worldwide.

Qilin Ransomware Gang Claims Cyberattack on Japanese Beer Giant Asahi

 

The Qilin ransomware group has claimed responsibility for the recent cyberattack on Japanese brewing giant Asahi, adding the company’s name to its dark web data leak site. The cybercriminals alleged that they had stolen over 9,300 files amounting to 27GB of confidential data, including financial documents, employee identification records, contracts, and internal reports. To substantiate their claims, the group published 29 images showing snippets of the stolen files. 

Asahi, Japan’s largest beer manufacturer, employs around 30,000 people and produces approximately 100 million hectoliters annually, generating close to $20 billion in revenue. The company suffered significant operational disruptions following the attack. On September 29, Asahi temporarily halted production at six of its domestic facilities, later confirming on October 3 that a ransomware attack had crippled its systems and led to data exfiltration. 

At first, no threat actor took public credit for the breach. However, the Qilin ransomware group eventually listed Asahi among its victims, likely after ransom negotiations failed. Qilin, which emerged in 2023, is known as a multi-platform ransomware operation capable of targeting both Windows and Linux systems. The group has been associated with other notorious hacker collectives such as Scattered Spider and, more recently, North Korean state-linked actors. 

Qilin’s tactics include exploiting vulnerabilities in edge network devices, deploying credential theft tools, and developing sophisticated encryption mechanisms to hinder recovery. The group has previously targeted high-profile organizations including Nissan, Inotiv, Lee Enterprises, major hospitals within London’s NHS network, and automotive supplier Yangfeng.

In its post, Qilin claimed that the Asahi ransomware attack could result in losses exceeding $335 million due to production halts affecting six breweries and more than thirty beer labels. Despite the claims, Asahi has not verified the authenticity of the leaked files. In a statement to BleepingComputer, a company spokesperson confirmed that the matter remains under active investigation and declined to comment further. 

The company also shared that production of its flagship beer, Super Dry, has resumed through a temporary manual ordering system. While Asahi’s factories are not yet operating at full capacity, shipments for additional labels are expected to restart by October 15. However, as a direct consequence of the cyberattack and ongoing disruptions, Asahi announced it would delay the launch of new products that were initially planned for October 2025. 

The attack on Asahi underscores the growing reach and sophistication of ransomware groups like Qilin, whose increasingly destructive campaigns continue to target global corporations across industries, threatening both economic stability and consumer trust.
