Nissan Fukuoka data breach exposes 21,000 customers; no card data

Nissan Motor Co confirmed that about 21,000 customers who purchased vehicles or used services at the Nissan Fukuoka branch have been affected by a personal data leak after an unauthorized attack on Red Hat servers that support its customer management system.

The company said the breach exposed customer names, phone numbers, email addresses, and related sales information. It noted that credit card data was not involved, limiting the risk of direct financial loss. That offers some reassurance, even if it doesn’t fully put privacy concerns to rest.

Red Hat detected the intrusion on September 26, 2025, and Nissan was notified on October 3. In the wake of the incident, the two companies launched an investigation to gauge the scope of the damage and put measures in place to head off a repeat.

Nissan is notifying affected customers and providing guidance on protecting personal data, while Red Hat has strengthened server monitoring and security to minimize the chance of another break-in. As experts note, episodes like this are a reminder that cybersecurity requires constant oversight and regular updates.
