Yamaguchi Financial Group, unauthorized access to subsidiary’s employee benefits app raises possibility of personal information leakage

Yamaguchi FG announced on 22 that its subsidiary's welfare benefits apps, Well Support and Well Support Plus, had been subject to unauthorised access and that personal information may have been leaked externally. The services concerned are for corporate customers, and the group said there was no impact on its financial services.

The potential leak resulted from unauthorised access from outside the company, and Yamaguchi FG explained that the apps were not connected to the systems of Yamaguchi FG or its subsidiary banks. It has not disclosed the specific types or volume of information that may have been leaked at this time.

The company is working to identify the cause and scope of the impact, and said it would disclose the status of notifications to customers and user companies, as well as its future response policy, at a later date.
