Japan's largest brewer Asahi was forced to halt production at most of its 30 factories after a ransomware attack last month disrupted operations from beer shipments to accounting systems. The company now says personal data may have been stolen during the breach.

All facilities have partially reopened, but computer systems remain down, forcing staff to process orders using pen, paper, and fax machines. Russia-based ransomware group Qilin claimed responsibility for the attack.

Asahi is investigating the extent of data theft and will notify affected individuals if confirmed. The attack only impacted Japanese operations, which represent half of the company's sales, leaving international brands like Peroni and Grolsch unaffected.
