Detailed information regarding the incident was covered in a report by <a href="https://www.bleepingcomputer.com/news/security/nippon-columbia-malware-incident-exposes-86-million-karaoke-fan-records/">BleepingComputer</a>.

Outsourced Data Handling and Discovery of the Infection
Daiichi Kosho outsources the handling of its customers’ personal information to Nippon Columbia Group (NCG). NCG is a prominent Japanese entertainment group whose diverse business operations encompass music, video, and game software production and distribution, alongside artist management responsibilities.
According to the disclosures, the record company informed Daiichi Kosho on October 5 that it had successfully discovered malware on an employee’s computer. The affected system was promptly isolated by the following day.

Daiichi Kosho reported that the exposed data contains records for 93,000 employees alongside 8,631,000 customers. The entertainment giant further noted that the security incident may impact visitors and users associated with several specific brands and locations.
Among the potentially affected venues and services are BIG ECHO, MEGA BIG, Karaoke CLUB DAM, Banana Club, B-GARAGE, and DK Dining.

To keep the public informed, the firm provided an official <a href="http://www.dkkaraoke.co.jp/news/newsletter/261009_1.html">update on Friday</a>, though it did not provide additional information regarding the possibility of an actual data leak.
Security Status and Customer Recommendations

In response to the contractor breach, NCG reset passwords and other authentication credentials. The contractor continues investigating both the cause and scope of the incident to determine whether any data has been leaked online.
As a general security recommendation, users are advised to remain highly suspicious of unsolicited communications via email, SMS, or phone calls that request payments or ask for sensitive personal or financial information.
