The Japan Shopping Centers Association announced that Blastmail, an external service, had been accessed without authorization and that some reader data registered with the service had been leaked. The cause and scope of the impact are currently under investigation.
The leaked data reportedly covers all registered newsletter recipient information, including personally identifiable information such as names, phonetic readings, email addresses, company names, organization names, department names and job titles.
The association has temporarily suspended newsletter distribution and subscription and cancellation procedures, and said that the timing of the service's resumption is undetermined. Blastmail is an external cloud service independent of the association, and the association's systems and business are reportedly unaffected.
