Cybersecurity researcher Sam Curry has discovered a vulnerability that allows cyberattacks on Honda, Nissan, Infiniti and Acura vehicles through SiriusXM's connected vehicle service.
According to cybersecurity expert Sam Curry, this problem can be used to:
- unlocking doors;
- engine start;
- vehicle detection;
- signaling to the car.
Moreover, for all these actions it is enough to know the VIN-number of the car.
More than 10 million vehicles in North America use SiriusXM Connected Vehicles, including Acura, BMW, Honda, Hyundai, Infiniti, Jaguar, Land Rover, Lexus, Nissan, Subaru and Toyota.
The security system provides the following functions, among others:
- automatic collision notification;
- remote unlocking of doors,
- remote engine start
- help finding a stolen car
- integration of the car with the "smart home" system, etc.
The vulnerability is related to an authorization error in a telematics program that allows receiving personal data of the victim, as well as executing commands on the car by sending a specially crafted HTTP request containing the VIN number to the SiriusXM endpoint (“telematics.net”).
Curry also described a separate vulnerability affecting Hyundai and Genesis cars, which, using registered email addresses, allows hackers to remotely control the locks, engine, headlights and trunks of cars manufactured after 2012.
By reverse engineering the MyHyundai and MyGenesis apps and inspecting API traffic, the researchers found a way to bypass the email verification step and remotely take control of the target vehicle's functions. “By adding a CRLF character to the end of a pre-existing victim email address during registration, we were able to create an account that bypassed the JWT and email parameter comparison check,” Curry explained.
For now, SiriusXM and Hyundai have released patches to address the shortcomings.
Forbes recently reported that federal law enforcement, along with Immigration and Border Protection, are using technology that uses vulnerabilities in media systems to extract data from 10,000 different car models. In 2022, immigration officers and police officers increasingly began to collect evidence in this way - sometimes it gives more information than the criminal's phone.
