Major Automaker’s Dealership Flaws Expose Cars to Hacking and Data Theft

Summary Points

1. Vulnerabilities Exploited: A researcher discovered significant vulnerabilities in an unnamed automaker’s dealership systems that could facilitate remote hacking of vehicles and unauthorized access to personal information.

2. Extensive Access Achieved: By exploiting API vulnerabilities, the researcher created a ‘national admin’ account, gaining full access to the platform used by over 1,000 US dealerships for vehicle management.

3. Remote Vehicle Control: The researcher could transfer vehicle ownership to his account, enabling him to remotely track, unlock, and start cars manufactured since 2012 with standard telematics modules, using just the victim’s name.

4. Industry-Wide Risks: The findings highlight systemic security risks across dealership-manufacturer platforms, emphasizing the need for broader industry improvements rather than targeting individual companies.

The Core Issue

Recently, Eaton Zveare, a security researcher affiliated with Traceable, unveiled significant vulnerabilities in the dealership systems of a major automaker during the DEF CON hacking conference. These security flaws, hidden within an online platform utilized by over 1,000 U.S. dealerships, could have allowed malicious actors to remotely commandeer vehicles and access sensitive customer data. Zveare’s explorations revealed that, despite the necessity for an invitation to register for the service, he could manipulate certain functionalities and API weaknesses to create a ‘national admin’ account. This access enabled him to alter vehicle ownership and interact with the car’s functionalities, including tracking its location and starting the engine—an exploit that could potentially affect any vehicle model produced since 2012 equipped with a standard telematics module.

Zveare’s investigative efforts have not been confined to just one automaker; he has previously identified weaknesses across several leading brands, including Honda and Toyota. Although the name of the automaker involved in his latest findings remains undisclosed, Traceable emphasizes that the objective of this research transcends individual companies. Instead, it aims to shine a light on the broader systemic vulnerabilities inherent in dealership-manufacturer platforms. By refraining from naming the automaker, Traceable seeks to steer the conversation towards essential improvements in security protocols industry-wide, rather than focusing on singular accountability.

Risks Involved

The vulnerabilities unearthed in a leading automaker’s dealership systems epitomize a profound systemic risk that could reverberate beyond the confines of the affected company, threatening a cascade effect across the automotive ecosystem and beyond. As dealership platforms increasingly rely on internet connectivity to streamline operations, they inadvertently expose sensitive data and critical functionalities not only to potential attackers but also to ripple effects impacting associated businesses, users, and organizations. Should these vulnerabilities be exploited, malicious actors could hijack vehicle systems, compromise customer personal information, and manipulate operational processes, fostering distrust among consumers and undermining the reputation of the entire automotive sector. This erosion of confidence could dissuade users from engaging with both dealership services and associated financial institutions, while also resulting in regulatory scrutiny that impacts compliance and operational stability for businesses that depend on secure digital interactions. Consequently, the implications extend far beyond individual dealerships; they encompass a collective urgency for fortified cybersecurity measures and heightened vigilance across the automotive industry.

Possible Remediation Steps

The urgency of addressing vulnerabilities in major automaker dealership systems cannot be overstated, as delays in remediation can have dire consequences for both security and customer trust.

Mitigation & Remediation Steps

1. System Audits: Conduct comprehensive assessments to identify vulnerabilities.
2. Software Updates: Regularly apply patches to eliminate known security flaws.
3. User Training: Provide education for staff on recognizing and preventing data breaches.
4. Access Controls: Implement stringent measures to restrict access to sensitive information.
5. Incident Response Plan: Establish and rehearse procedures to swiftly address breaches.
6. Encryption Protocols: Employ strong encryption for sensitive data to safeguard against theft.
7. Third-Party Security: Vet partners and vendors to ensure compliance with robust security standards.
