Do you trust the security of your vehicle's smart features and connected data?
A study analyzing 413 software vulnerabilities between January 2022 and September 2024 highlights growing security risks in connected vehicles. These findings underscore the dangers of third-party software integration in modern automotive systems.
Why it matters
Modern vehicles rely on complex software to connect with cloud services, satellites, and smartphones for navigation and entertainment. This connectivity increases the surface area for potential security breaches, exposing sensitive driver and vehicle data.
Researchers categorized 45 percent of the 413 identified vulnerabilities as high severity and 16 percent as critical. External applications now account for more than one-third of all identified security weaknesses in connected vehicles.
The players
Volkswagen Group
This major automotive manufacturer experienced a data exposure incident where vehicle location information was found accessible online.
The details
Vulnerabilities frequently enter vehicle systems through third-party software libraries integrated during development. In December 2024, researchers found that location data for 800,000 Volkswagen Group vehicles was accessible online due to unsecured Amazon Web Services credentials held by a third-party vendor.
Timeline
In 2015, researchers demonstrated the ability to remotely interfere with a Jeep Cherokee's steering, brakes, and accelerator.

Roadmap
The automotive industry is transitioning into a software-defined ecosystem, increasing reliance on third-party code. This evolution mirrors the early security challenges faced by personal computing, forcing manufacturers to address vulnerabilities as a core component of vehicle design.
Drivers of connected vehicles should remain aware that software dependencies create potential risks for data privacy and remote system access. Regularly updating vehicle software through official manufacturer channels can help mitigate some exposure to known security flaws.
The takeaway
Vehicle owners should prioritize data privacy settings and use manufacturer-provided apps with caution. As cars become more connected, security should be a primary consideration for both developers and consumers alike.
