SUMMARY
- Sensitive data for 800,000 Volkswagen Group EVs was exposed on an unsecured cloud server.
- The data leak, discovered by a whistle-blower, included GPS data and vehicle status, enabling owner tracking.
- Affected users included politicians, police, and intelligence employees, with most vehicles in Europe.
- The data leak revealed personal routines and locations, posing serious privacy risks.
- The issue stemmed from Cariad’s system misconfiguration, which has since been addressed.
A recent report from the German news outlet Spiegel has revealed a significant security breach impacting hundreds of thousands of Volkswagen Group electric vehicle owners. The investigation found that sensitive location data for 800,000 vehicles, including those from Volkswagen, Audi, SEAT, and Skoda, was left exposed on an unsecured cloud server for months.
The vulnerability was discovered by an anonymous whistle-blower and reported to the Chaos Computer Club (CCC), a prominent European hacker association. The exposure included personal data, including GPS coordinates and vehicle status, including detailed information about VW ID.3 and ID.4 owners stored on an unsecured Amazon cloud server. This allowed anyone with the right know-how to track the movements and habits of affected owners.
Reportedly, the impacted EVs were located worldwide with the majority found in Germany and other parts of Europe. The affected owners not just include ordinary citizens but also prominent figures like German politicians, police officers, and even suspected intelligence service employees just like in October 2023 when a third-party contractor exposed over 500,000 Irish Police vehicle seizure records.
This exposure extended far beyond simple vehicle location tracking. By linking vehicle data with other personal information, the researchers were able to gain unprecedented insights into the daily lives of affected owners.
For example, according to Spiegel’s report, it was able to track the movements of two German politicians with alarming precision, pinpointing their locations at various locations including a retirement home and military barracks, and profiling a mayor with her car tracking her movements from her work to her physical therapist.
That’s not all! Spiegel discovered terabytes of data on Amazon cloud storage, including the precise location of 460,000 vehicles, which could reveal crucial details of their owners. Moreover, the data also included information about the Hamburg police department’s electric cars, politicians, business leaders, Federal Intelligent Services employees, and the US Air Force’s Ramstein Air Base drivers.
The root of this security failure lies within Cariad, the Volkswagen Group’s software division. The company confirmed that a misconfiguration within their systems allowed unauthorized access to the sensitive data.
While Cariad insists that no financial or personally identifiable information was compromised, the potential for misuse of the exposed location data remains a significant threat. Cybercriminals could exploit this information for a variety of malicious purposes, including targeted stalking, blackmail, and even physical attacks.
The CCC promptly contacted Lower Saxony’s State Data Protection Officer, Federal Ministry of the Interior, and other security bodies, and gave VW Group and Cariad 30 days to address the issue before going public. Cariad’s technical team promptly and responsibly blocked unauthorized access to customer data.
