Large-scale leaks of personal information caused by unauthorized access are occurring one after another. Bookoff Group Holdings announced on the 9th that up to about 6.43 million member records may have leaked due to unauthorized access, and Daiichikosho, which operates the karaoke chain Big Echo, also disclosed that roughly 8.72 million pieces of personal information may have been leaked. In both cases, the leaked information includes members' and customers' names, dates of birth, email addresses, and phone numbers, and both companies said that as of the time of their announcements no misuse by third parties had been confirmed, urging affected individuals to be wary of suspicious emails and phone calls. At Bookoff, a subsidiary that manages member information was affected, while at Daiichikosho, a system operated by an outsourcing contractor handling personal information was hit by the unauthorized access. Both companies commented, "We deeply apologize for causing our customers enormous worry and inconvenience," and are hurrying to implement measures to prevent a recurrence.
