Hyundai AutoEver America (HAEA) Data Breach (2025)

Hackers infiltrated Hyundai AutoEver America’s (HAEA) systems between February and March 2025, gaining unauthorized access for nine days before detection. The breach exposed sensitive personal data of approximately **2,000 customers**, including **names, Social Security numbers, and driver’s license details**, though the company could not confirm if the data was exfiltrated. HAEA, a digital subsidiary of Hyundai Motor Group managing software for Hyundai, Kia, and Genesis vehicles, serves **2.7 million users**, but the impact was limited to a small subset. The incident prompted an external cybersecurity investigation, two years of free credit monitoring for affected individuals, and a dedicated hotline for support.The breach underscores escalating risks in automotive cybersecurity, particularly as modern vehicles collect vast amounts of driver data (e.g., location history, payment info). While HAEA downplayed the scale, the exposure of **personally identifiable information (PII)**—even for a limited group—raises concerns about data protection practices across the industry, especially following regulatory actions like the FTC’s ban on GM’s driver data sales and Senate scrutiny of automakers’ privacy policies.

Hyundai AutoEver America (HAEA) Cyberattack and Data Breach (2025)

Hyundai AutoEver America (HAEA), the North American IT subsidiary of Hyundai, suffered a cyberattack in early 2025 that lasted over a week (February 22 – March 2). The breach exposed sensitive customer data, including **Social Security numbers (SSNs) and driver’s license information**, putting at least **2.7 million vehicle owners (Hyundai, Kia, Genesis)** at risk of identity theft and financial fraud. While the exact number of affected individuals remains unclear, Massachusetts reported **7 residents impacted**, and California’s Attorney General website suggests **over 500 Californians** were affected, triggering mandatory breach notifications.The attack enabled threat actors to create **detailed victim profiles** for fraud, including fake identities and financial exploitation. HAEA claimed to have **hardened security**, engaged third-party experts, and notified law enforcement. This marks Hyundai’s **second major breach in two years**, following a 2024 ransomware attack by **Black Basta**, which stole **3TB of data** from Hyundai Motor Europe. The incident underscores systemic vulnerabilities in Hyundai’s cybersecurity posture, with repeated exposures of high-value personal data.

Hyundai Data Breach Exposes Social Security Numbers and Driver's Licenses

Hyundai suffered a major data breach in February 2024, disclosed months later after a prolonged investigation. Hackers infiltrated **Hyundai AutoEver America (HAEA)**, the digital backbone for Hyundai, Kia, and Genesis in North America, gaining **unrestricted access for nine days** (February 22–March 2). The breach exposed highly sensitive customer data, including **full names, Social Security numbers (SSNs), and driver’s license information**—critical identifiers for identity theft and fraud. HAEA’s systems, which manage dealership operations, remote vehicle software, and customer purchase processing, were compromised, allowing attackers to exfiltrate data undetected. This marks Hyundai’s **third major security incident in three years**, highlighting systemic vulnerabilities in its digital infrastructure. The delayed disclosure underscores the severity, as victims remained unaware while their data circulated in criminal networks. The breach’s scale and the nature of stolen data pose long-term risks, including financial fraud, phishing, and reputational damage to Hyundai’s brand trust.

Hackers gained unauthorized access to HAEA’s IT environment, compromising **sensitive information**—including **Social Security numbers (SSNs), driver’s license details, names, and potentially other identifiers**—linked to over **2 million users and nearly 3 million vehicles**. The stolen data heightens risks of **identity theft, financial fraud, and long-term reputational damage** to Hyundai’s connected vehicle ecosystem. While the exact victim count remains unclear, state filings in **Massachusetts and Maine** confirm broad exposure. HAEA has initiated **customer notifications and credit monitoring**, but criticism persists over **delayed transparency and systemic vulnerabilities** in automotive IT infrastructure. The breach follows a **2023 incident** affecting European customers, reinforcing concerns about **recurring security gaps** in the sector.

Lessons Learned
Connected vehicle ecosystems are high-value targets for cybercriminals due to vast amounts of sensitive PII. Lack of transparency in breach disclosures can exacerbate reputational damage and erode customer trust. Systemic vulnerabilities in automotive IT infrastructure require robust encryption, multi-factor authentication, and zero-trust architectures. Supply chain security in the auto industry is fragile, especially as vehicles integrate IoT and AI technologies. Proactive cybersecurity measures, such as regular penetration testing and employee phishing training, are critical to mitigating risks.
Recommendations
Freeze credit files to prevent unauthorized access. Enable fraud alerts with credit bureaus. Monitor credit reports regularly for suspicious activity. Consider identity theft protection services. Adopt AI-driven threat detection systems for real-time monitoring. Implement zero-trust architectures and multi-factor authentication (MFA). Conduct regular penetration testing and vulnerability assessments. Enhance employee training on phishing and social engineering threats. Establish clear, timely breach disclosure protocols to maintain transparency. Invest in robust encryption for sensitive data, especially PII. Advocate for mandatory breach reporting timelines to ensure swift public disclosure. Develop international standards for automotive data security and connected vehicle cybersecurity. Enforce stricter oversight of data handling practices in the automotive sector. Encourage collaboration between automakers, IT providers, and cybersecurity firms to share threat intelligence. Prioritize digital resilience in connected mobility to protect against evolving cyber threats. Integrate cybersecurity into the design phase of vehicle development (security by design). Establish industry-wide best practices for securing IoT and cloud-based automotive services. Foster public-private partnerships to address systemic vulnerabilities in automotive IT infrastructure.

Hyundai Motor Group Data Breach Affecting 2.7 Million Customers

Hyundai AutoEver America (HAEA), the IT division of Hyundai Motor Group, suffered a **massive data breach** between **February 22 and March 2, 2025**, compromising the personal data of **up to 2.7 million customers**, including those of Hyundai, Kia, and Genesis. The stolen information includes **names, Social Security Numbers (SSNs), driver’s license numbers, addresses, and phone numbers**—highly sensitive data that can be exploited for identity theft, phishing, and financial fraud. While HAEA claims to have blocked network access during the attack, the delay in notifying affected customers (letters sent in **October 2025**, seven months later) raises concerns about transparency and incident response. The breach also risks **cross-referencing stolen data with other leaked databases**, enabling cybercriminals to craft **targeted phishing attacks** to extract further credentials or funds. HAEA has offered **two years of free credit monitoring via Epiq** (a firm that itself suffered a ransomware attack in 2020), but the recurring nature of such incidents—including prior Hyundai breaches in **2023 and 2024**—highlights systemic vulnerabilities in the automaker’s cybersecurity posture. The breach’s scale and the sensitivity of the exposed data pose **long-term reputational and financial risks** for customers and the company.
