Nissan Confirms Thousands of Customers Exposed in Red Hat Security Breach
🎙️ Dive Deeper with Our Podcast!
Nissan Motor Co. Ltd. has disclosed that approximately 21,000 customers in Japan had their personal information compromised following a significant security breach at Red Hat, the enterprise software company contracted to develop customer management systems for Nissan’s sales operations. This incident underscores the growing cybersecurity risks that organizations face through their third-party vendors and technology partners.
The breach, which occurred in September 2024, highlights a critical vulnerability in modern business operations: supply chain security. When companies outsource critical functions like customer relationship management to technology providers, they inherently extend their attack surface beyond their direct control. For Nissan, this meant that despite their own security measures, customer data became vulnerable through their relationship with Red Hat.
Understanding the Red Hat Breach That Affected Nissan
Red Hat, a prominent U.S.-based enterprise software company known for its open-source solutions, suffered a sophisticated cyberattack that compromised sensitive data stored across 28,000 private GitLab repositories. The breach initially came to light when the threat actor group known as Crimson Collective claimed responsibility for stealing hundreds of gigabytes of confidential information.
The attack didn’t end with Crimson Collective. ShinyHunters, another notorious cybercriminal group, subsequently became involved by hosting samples of the stolen data on their extortion platform. This dual-threat approach significantly escalated pressure on affected organizations, combining data theft with public exposure tactics designed to force compliance with ransom demands.
For Nissan, the consequences materialized when Red Hat reported unauthorized access to data servers containing customer information from Nissan Fukuoka Sales Co., Ltd., one of the automaker’s regional sales companies in Japan. The breach demonstrates how cybercriminals increasingly target technology service providers as a means of accessing multiple downstream organizations simultaneously.
What Customer Information Was Compromised
Nissan confirmed that approximately 21,000 customers who purchased vehicles or received services at Nissan locations in Fukuoka, Japan, had the following personal information exposed:
The compromised data included customers’ full names, which cybercriminals can use to personalize phishing attacks and social engineering schemes. Physical addresses were also leaked, creating potential risks for identity theft and targeted physical scams. Phone numbers in the wrong hands enable scammers to conduct vishing attacks (voice phishing) that impersonate legitimate companies or government agencies.
Email addresses represent another valuable data point for criminals, as these can be used for phishing campaigns, spam distribution, and credential stuffing attacks across multiple platforms. Additionally, customer data used in sales operations was accessed, which could include vehicle preferences, service history, and communication records that help criminals craft more convincing fraud attempts.
Importantly, Nissan emphasized that financial information such as credit card details was not part of the compromised dataset. This limitation provides some reassurance that customers face reduced risk of direct financial fraud, though the exposed personal information still creates substantial identity theft and phishing risks.
The Growing Pattern of Nissan Cybersecurity Incidents
This Red Hat breach represents the second major cybersecurity incident affecting Nissan Japan in 2024. In late August, the company’s design subsidiary Creative Box Inc. (CBI) fell victim to a Qilin ransomware attack, demonstrating that Nissan faces threats both directly and through connected entities.
The pattern extends beyond Japan. In 2023, Nissan North America experienced a data breach that compromised personal information belonging to 53,000 employees. This incident targeted workforce data rather than customer information, but nonetheless revealed vulnerabilities in the company’s North American operations.
Nissan Oceania also suffered a significant breach in 2023 when Akira ransomware operators successfully attacked their systems, exposing data belonging to approximately 100,000 customers. This incident affected operations across Australia and New Zealand, demonstrating the global scope of threats facing the automotive manufacturer.
These repeated incidents across multiple geographic regions and business units suggest that Nissan faces persistent cybersecurity challenges. The automotive industry has become an increasingly attractive target for cybercriminals due to the vast amounts of customer data collected through sales, financing, service operations, and connected vehicle technologies.
Third-Party Risk Management in the Automotive Industry
The Nissan-Red Hat incident illustrates a fundamental challenge facing modern businesses: managing cybersecurity risks in complex vendor relationships. When organizations contract third-party providers for critical functions like customer relationship management, data storage, or software development, they create potential vulnerabilities outside their direct security control.
Automotive manufacturers like Nissan collect extensive customer information throughout the ownership lifecycle. From initial sales inquiries through financing applications, service appointments, warranty claims, and connected vehicle data, dealerships and manufacturers accumulate detailed profiles on their customers. When this data is processed or stored by third-party technology providers, it creates additional exposure points that threat actors actively exploit.
The Red Hat breach succeeded through compromise of GitLab repositories, which are commonly used for software development collaboration and version control. These repositories often contain not just source code but also configuration files, credentials, and data samples that developers use for testing purposes. When cybercriminals gain access to such repositories, they can extract sensitive information that was never intended to be externally accessible.
For businesses relying on third-party vendors, this incident emphasizes the importance of comprehensive vendor risk assessments, continuous security monitoring, and contractual obligations regarding data protection standards. Organizations must establish clear protocols for incident notification, data breach response, and customer communication when vendor-related incidents occur.
What Affected Customers Should Do Now
If you purchased a vehicle or received services at Nissan Fukuoka Sales locations, you should take proactive steps to protect yourself against potential fraud. Begin by monitoring all financial accounts for suspicious activity, even though credit card information was not reportedly compromised. Criminals can use personal information to attempt account takeovers or open new accounts fraudulently.
Be extremely cautious about unsolicited communications claiming to be from Nissan or related to vehicle services. Phishing attacks following data breaches are common, as scammers leverage leaked information to craft convincing messages. Verify any requests for information by contacting Nissan directly through official channels rather than responding to emails or messages.
Consider placing fraud alerts or credit freezes with major credit bureaus, particularly if you’re concerned about identity theft risks. These measures make it more difficult for criminals to open new accounts using your personal information, though they may create minor inconveniences for your own legitimate credit applications.
Update passwords for any online accounts associated with your Nissan services, and ensure you’re using strong, unique passwords for each important account. Enable multi-factor authentication wherever possible to add an additional security layer beyond just passwords.
Remain vigilant for at least 12 to 24 months following the breach, as criminals sometimes delay exploitation of stolen data to avoid connection with the original incident. Report any suspicious activity immediately to both the affected organization and appropriate law enforcement agencies.
Preventing Future Third-Party Security Breaches
Organizations can implement several critical measures to reduce risks associated with vendor relationships. Comprehensive vendor security assessments should evaluate potential partners’ cybersecurity practices before contracts are signed, including their incident response capabilities, data encryption standards, and security certifications.
Continuous monitoring of vendor security posture throughout the relationship helps identify emerging risks before they result in breaches. This includes regular security audits, penetration testing, and review of vendors’ own third-party relationships that might create additional exposure.
Contractual agreements should clearly define data protection obligations, breach notification timelines, liability for security incidents, and requirements for cybersecurity insurance coverage. These provisions establish expectations and provide recourse when vendor security failures impact customer data.
Data minimization principles limit exposure by ensuring vendors only receive information absolutely necessary for their contracted functions. Regularly reviewing what data is shared with third parties and eliminating unnecessary data transfers reduces potential breach impact.
Implementing zero-trust security architectures helps organizations maintain control over data even when processed by external parties. These frameworks assume that no user, device, or system should be automatically trusted, requiring continuous verification regardless of whether they’re internal or external to the organization.
For automotive dealerships and manufacturers specifically, the complexity of modern operations requires robust third-party risk management programs. Connected vehicles, mobile applications, online sales platforms, and customer relationship management systems all create potential vulnerability points that demand comprehensive security oversight.
