In 2015, security researchers demonstrated that possibility in a Jeep Cherokee.

Researchers at Sweden's University of Gothenburg and Chalmers University of Technology analyzed 413 previously reported automotive software vulnerabilities.

The team examined another way flaws can enter automotive software, through ready-made code components called libraries.

Using five scanning tools, the researchers examined 20 open-source projects used in automotive software or its development.

Security, Basu said, "should be built in from the beginning and tested throughout a vehicle's lifetime."
