Asahi did not state the attacker’s identity or demands. Ransomware group Qilin – which has previously hacked other major firms – had claimed responsibility for the Asahi attack.
The beer maker said in its preliminary findings that it discovered a disruption at one of its data centres on 29 September.
It said that although the system was quickly isolated, investigators found the attacker had already infiltrated the network, encrypted its data and deployed ransomware – a virus that blocks access to files until a ransom is paid.
Some data in the affected computers, along with personal information stored in the hacked servers, were also potentially exposed, said Asahi.
It includes personal details of 1.52 million customers, specifically their names, gender, addresses and contact information.
