Massive Security Breach: Hacker Remotely Unlocks Cars Through Carmaker's Web Portal Vulnerabilities
A cybersecurity researcher has exposed critical vulnerabilities in a major automaker's web portal that allowed unauthorized remote access to vehicles, including the ability to unlock doors, start engines, and track locations. The discovery highlights growing concerns about automotive cybersecurity as vehicles become increasingly connected.
The Breach That Could Have Changed Everything
Security researcher Sam Curry recently uncovered a series of devastating flaws in an unnamed automaker's web infrastructure that could have given malicious actors unprecedented control over connected vehicles. Through a combination of authentication bypasses and API vulnerabilities, Curry demonstrated the ability to remotely access nearly any function of affected vehicles – from unlocking doors to starting engines and accessing real-time location data.
The vulnerability chain began with weak authentication mechanisms in the manufacturer's customer portal, allowing Curry to impersonate legitimate vehicle owners. Once inside the system, poorly secured APIs provided direct access to vehicle control functions that should have been heavily protected behind multiple security layers.
A Perfect Storm of Security Failures
Authentication Weaknesses
The primary vulnerability stemmed from inadequate user verification processes. The system relied on easily obtainable information like VIN numbers and basic personal data that could be harvested from various sources. Once authenticated, the system granted broad access to vehicle functions without additional verification steps.
Unprotected API Endpoints
Perhaps more concerning was the discovery that critical vehicle control APIs lacked proper authorization checks. These endpoints, designed to allow legitimate remote services like mobile apps to communicate with vehicles, were accessible to anyone who could authenticate to the broader system.
Real-Time Location Tracking
Among the most privacy-invasive capabilities was unrestricted access to vehicle location data. The researcher could track any affected vehicle in real-time, creating serious stalking and personal safety risks for owners who had no idea their movements were being monitored.
The Scope of Impact
While the specific automaker hasn't been publicly identified, the vulnerability reportedly affected hundreds of thousands of connected vehicles across multiple model years. The scope suggests this wasn't an isolated coding error but rather systemic security architecture problems that developed over years of rapid connected car feature rollouts.
The incident joins a growing list of automotive cybersecurity breaches. In 2015, researchers Charlie Miller and Chris Valasek famously demonstrated remote control of a Jeep Cherokee, leading to a 1.4 million vehicle recall. More recently, security firms have identified vulnerabilities in Tesla's systems, Ford's mobile apps, and various aftermarket connected car devices.
Industry Response and Implications
Responsible Disclosure
Following responsible disclosure practices, Curry reported the vulnerabilities directly to the affected manufacturer rather than exploiting them maliciously or immediately going public. The automaker reportedly responded quickly, implementing patches within weeks of notification.
Regulatory Attention Growing
The incident comes as regulators worldwide are paying increased attention to automotive cybersecurity. The European Union's new cybersecurity regulations for vehicles took effect in 2022, requiring manufacturers to demonstrate robust security measures throughout a vehicle's lifecycle. Similar regulations are being considered in the United States and other major markets.
Insurance and Liability Questions
As connected car vulnerabilities become more common, questions about liability and insurance coverage are becoming pressing concerns. If a vehicle is stolen or used in a crime due to a manufacturer's security flaw, determining responsibility between automakers, software vendors, and vehicle owners remains legally complex.
Protecting Yourself in the Connected Car Era
While consumers have limited control over manufacturer security practices, several steps can help minimize risks:
- Regularly update vehicle software when prompted
- Monitor your vehicle's mobile app for unusual activity
- Be cautious about sharing VIN numbers and personal information
- Consider whether connected features are worth potential security risks
- Stay informed about recalls and security updates for your specific vehicle model
The Road Ahead
This latest breach underscores that automotive cybersecurity remains in its infancy despite years of connected car development. As vehicles become increasingly software-defined and connected to cloud services, the attack surface continues to expand faster than security practices can mature.
The automotive industry must prioritize security-by-design principles, implement robust testing procedures, and develop rapid response capabilities for emerging threats. For consumers, the connected car revolution offers undeniable convenience – but it comes with cybersecurity risks that traditional vehicles never faced.
The question isn't whether more automotive security breaches will occur, but how quickly the industry can evolve its security practices to match the sophistication of modern cyber threats.
