Nippon Columbia malware incident exposed data for 8,631,000 customers

Daiichi Kosho says the incident leaves millions of customer records exposed, but it has not confirmed any theft or leak.

Daiichi Kosho says a malware incident at its contractor Nippon Columbia exposed records for 93,000 employees and 8,631,000 customers tied to its karaoke and dining businesses, making this a large personal-data disclosure for a major Japanese entertainment operator. The company says the affected data includes names, genders, birth dates, email addresses, and phone numbers, but not passwords. It has not confirmed theft or leakage so far, although it is warning customers to watch for suspicious calls, emails, texts, or payment requests. Daiichi Kosho says its own systems were not breached, and Nippon Columbia has reset credentials while investigating how far the incident went and whether anything was posted online.
