Tokyo, Japan – October 8, 2025 – Beverage giant Asahi Group is grappling wiht the aftermath of a significant cyberattack, claimed by the prolific ransomware group Qilin.The incident has caused disruption to production at the company’s six Japanese beer plants, impacting supply chains and raising concerns about the vulnerability of critical infrastructure.
The Cyberattack and production Halt
On September 29, Asahi Breweries, a subsidiary of Asahi Group, initially disclosed it had fallen victim to a hacking attack. Production at its Japanese facilities was temporarily suspended as a precautionary measure. As of Monday, October 2, limited production had resumed, but the full extent of the damage and data compromise remained unclear.
The ransomware group, Qilin, asserted responsibility for the attack on Tuesday, posting 29 images purportedly depicting internal asahi documents on their website. According to Qilin, over 9,300 files, totaling approximately 27 gigabytes of data, were exfiltrated during the breach. Authorities are currently working to verify the authenticity of these claims.
Qilin Ransomware: A Growing Threat
Qilin operates on a “ransomware-as-a-service” model, allowing affiliates to deploy ransomware in exchange for a share of the profits generated from accomplished extortion. Since its emergence in 2022, Qilin has been connected to at least 870 attacks globally, according to data compiled by cybercrime research platform eCrime.ch.
This is not the first time Qilin has targeted significant entities. In June 2024, the group compromised British diagnostic services provider Synnovis. This earlier attack was tragically linked to the death of a patient at a London hospital in June 2025, highlighting the potentially devastating real-world consequences of ransomware attacks.
Asahi Group has remained tight-lipped regarding the specifics of the current situation,stating only that the matter is under inquiry. A company spokesperson declined to comment on any potential ransom demands or ongoing negotiations with the attackers.
