SoftBank announced on October 19th that it confirmed attempted unauthorized access to some systems of its member website "My SoftBank." As a safety measure for customer information, it has temporarily suspended the websites for "My SoftBank," "My Y!mobile," and "My Menu." The suspension began on October 17th at 8:00 AM, and the resumption date is currently unknown.
The affected services are the web versions of the three member sites for users. The app versions of each service remain available.
The attempted unauthorized access occurred on October 17th. The company's monitoring system automatically detected unusual activity in some related systems of My SoftBank, reportedly leading to the partial suspension of related systems and the blocking of suspicious communication paths from external sources. SoftBank states it is proceeding with maintenance work to further strengthen security.
It is currently unknown whether customer information was leaked. SoftBank states it will announce the resumption of the websites once preparations are complete.
