Cyberattack Halts Asahi's Production, Threatens 'Super Dry' Supply

Japan's extensive digital supply chains have left the country vulnerable to cyberattacks, as evidenced by the recent Asahi incident. Asahi Group Holdings Ltd. has revealed that cyber-attackers used ransomware to halt its domestic factories' operations, leading to potential shortages of popular products like 'Super Dry' in convenience stores nationwide.

The attack, which occurred in late September 2025, has caused significant disruptions. Asahi is currently prioritizing product supply and finding alternative means to fulfill orders while working towards a full system recovery. Some businesses, such as Marugen Ramen and Kisoji, are considering switching to other beer brands due to Asahi's supply issues. As of early October, there is no public confirmation or attribution regarding who was responsible for the attack.

The incident has raised concerns about cybersecurity in Japan. With 116 reported ransomware cases in the first half of 2025, matching the six-month record set in the second half of 2022, it's clear that more needs to be done to protect against these threats. The attack on Asahi serves as a wakeup call about the importance of cyber-literacy among consumers.

Asahi's shares have dropped by around 7% this week due to the disruption caused by the cyberattack. The company is currently investigating the extent of the breach and working to resume full operations. While the responsible party remains unknown, the incident highlights the need for improved cybersecurity measures to protect Japan's extensive digital supply chains.
