AKB48 Mail: app access cut after intrusion

Joint operators BEENOS Entertainment and DH announced on 28 October that they had detected an intrusion into the app. They cut its server connection at about 11:00 that day; launching it shows a connection error and the service is unavailable. [1]

At disclosure, no trace of customer data exfiltration had been found, and the cause and scope were under investigation. The app had already been scheduled to close on 30 November. On 5 November the operators clarified that the repica email-address leak was a separate incident. [1] [2]
