Japan: Hokusen addresses data breach potentially affecting 44,559 customers

Hokusen Co., Ltd. issued, on 16 May 2022, a notice in which it addressed a data breach potentially affecting the personal information of up to 44,559 customers. In particular, Hokusen confirmed that it discovered that personal information may have been leaked due to unauthorised access by a third party. In this respect, Hokusen noted that affected personal information included information, such as email addresses, passwords, names, addresses, dates of birth, gender, phone numbers, and account information. As a result of the incident, Hokusen stated that, based on the results of the investigation that will be conducted by a third-party research organisation, it will strengthen the system security measures and monitoring system to prevent recurrence, noting that it has already taken measures against attacks caused by SQL injections that caused the information leakage. Furthermore, Hokusen outlined that it reported the unauthorised access to the relevant Japanese ministries and organisations on 20 January 2022.
