In an era where vehicles are becoming increasingly connected, a significant security vulnerability has been discovered in Subaru's Starlink system, highlighting the growing cybersecurity challenges facing modern automotive technology. The breach, which has since been patched, exposed critical vulnerabilities that could have allowed malicious actors to gain unauthorized access to vehicles and sensitive user data.
The Security Breach
Security researchers Sam Curry and Shubham Shah uncovered a severe vulnerability in Subaru's Starlink connected vehicle service that affected cars across the United States, Canada, and Japan. The exploit required minimal information to execute - just a driver's surname combined with either their ZIP code, email address, phone number, or license plate number. This security flaw enabled unauthorized access to critical vehicle functions and sensitive user data.
Extent of Access
The vulnerability granted attackers unprecedented control over affected vehicles, including the ability to remotely start and stop the engine, lock and unlock doors, and track real-time location. More concerning was access to a full year's worth of detailed location history, accurate to parking spot locations. Personal information including home addresses, billing details, emergency contacts, and vehicle history were also exposed.
Technical Vulnerability
The breach stemmed from weaknesses in Subaru's employee portal and authentication system. While the Starlink login was supposedly protected by two-factor authentication and security questions, researchers discovered they could bypass these security measures by simply modifying website code. This implementation flaw effectively nullified the password protection system.
Subaru's Response and Ongoing Concerns
While Subaru responded swiftly by patching the vulnerability within 24 hours of notification, the incident raises serious questions about data access within the company. Current Subaru employees retain broad access to customer information, including location history and personal details, with minimal oversight. The company maintains this access is necessary for emergency services and support functions, though privacy advocates question the extent of data retention and access privileges.

Broader Industry Implications
This security breach exemplifies a larger trend in automotive cybersecurity vulnerabilities. As vehicles become more connected, they face increased risks of cyber attacks that could compromise user privacy and safety. The incident serves as a wake-up call for the automotive industry to strengthen their cybersecurity measures and reassess their approach to data protection and access controls.
