Japanese beer and beverage giant Asahi Group Holdings has not been able to resume production at domestic factories a day after a cyberattack and cannot foresee when it can be resumed, a company spokesperson said on Tuesday. 

The company has 30 plants in Japan making beer, beverage and food products, but it is still investigating whether all of them have stopped production, the spokesperson added.

The maker of Asahi Super Dry Beer, Nikka Whisky and Mitsuya Cider last night said its group companies in Japan suspended operations, including order processing, shipping and call centre functions, due to a cyberattack-caused system outage, although no personal information leakage has been confirmed.

The breach was announced on Monday, 29 September. The company said:

“At this time, there has been no confirmed leakage of personal information or customer data to external parties. 

“We are actively investigating the cause and working to restore operations; however, there is currently no estimated timeline for recovery. The system failure is limited to our operations within Japan.”
