Nissan Motor Corporation has officially confirmed a significant data breach resulting from unauthorized access to Red Hat servers operated by a third-party contractor tasked with developing a customer management system. The incident specifically affected Nissan Fukuoka Sales Co., Ltd., formerly known as Fukuoka Nissan Motor Co., Ltd. According to disclosures, Red Hat detected suspicious activity on its server environment on September 26, 2025, and promptly revoked the attacker’s access while deploying technical countermeasures to prevent further intrusion. However, notification to Nissan Motor was delayed, with Red Hat formally informing the automaker of the breach on October 3, 2025, at which point Nissan immediately reported the incident to Japan’s Personal Information Protection Commission in compliance with regulatory obligations. The breach led to the exposure of personal data belonging to approximately 21,000 customers, including names, physical addresses, telephone numbers, and partial email addresses. The compromised information was related to sales and service records used internally by Nissan’s dealer network. Importantly, Nissan emphasized that no credit card data, banking information, or payment details were involved, significantly reducing the likelihood of direct financial fraud. The exposed customer population consists of individuals who had purchased vehicles or received maintenance services through Nissan Fukuoka Sales. Nissan also clarified that the Red Hat server environment did not store additional customer datasets beyond those already identified, alleviating concerns of a wider compromise across other systems. At present, Nissan has stated that there is no evidence indicating the stolen data has been misused, monetized, or circulated on underground forums. Nonetheless, affected customers will be notified individually and provided with guidance on precautionary measures, including vigilance against phishing attempts, fraudulent phone calls, or impersonation scams. In response to the incident, Nissan Motor announced plans to strengthen oversight of third-party contractors, enhance information security controls, and review vendor risk management practices across its operations. The company issued a formal apology to impacted customers and business partners, reaffirming its commitment to improving cybersecurity governance and data protection standards.
