Japan's Largest Beer Producer Halts Operations Due to Hacker Attack

Asahi Group Holdings, the producer of Japan’s best-selling beer, has suffered a cyberattack that disrupted multiple operations. The incident forced the suspension of order processing and deliveries, while the company’s call center and customer support services were also taken offline.

Asahi is one of Japan’s largest breweries, controlling roughly one-third of the domestic beer market. The company employs around 30,000 people and reported annual revenue of nearly $20 billion USD in 2024. On the global stage, Asahi operates four regional divisions—Japan, Europe, Oceania, and Southeast Asia—and owns several prominent brands including Peroni, Pilsner Urquell, Grolsch, and Fuller’s.

The company confirmed that the attack affected only its Japanese operations. According to Reuters, all 30 of Asahi’s breweries in Japan were temporarily forced to halt production. Ordering and delivery functions, as well as customer support channels, remain suspended as the company works to restore systems.

Investigators are still determining the scope and nature of the breach. At this stage, there is no evidence that customer or personal data was compromised. Asahi has not yet provided a timeline for full recovery.

So far, no ransomware group or hacker collective has claimed responsibility for the attack.
