Daiichi Kosho is one of Japan’s leading karaoke system makers and operates 521 karaoke venues nationwide, including the popular Big Echo chain. The company outsources the handling of personal information to Nippon Columbia Group (NCG), a Japanese entertainment group involved in music, video and game software production and distribution, as well as artist management.
According to Daiichi Kosho, Nippon Columbia notified the company on October 5 that malware had been detected on an employee’s computer. The affected system was isolated the following day as the company began responding to the incident.
The potentially exposed information covers approximately 93,000 employees and 8,631,000 customers. The records include full names, genders, dates of birth, email addresses and telephone numbers.
The incident may affect customers associated with several Daiichi Kosho businesses and services, including BIG ECHO, MEGA BIG, Karaoke CLUB DAM, Banana Club, B-GARAGE and DK Dining.
Daiichi Kosho says it has not confirmed that the information was stolen or leaked. However, the company is advising customers to remain vigilant because the possibility of data exposure cannot be ruled out.
