In-vehicle communications and entertainment system hosts high-value or sensitive applications. API libraries facilitate communication and sharing of vehicle data. These API libraries are vulnerable to reverse engineering and tampering attacks and may even result in loss of passenger safety. Attackers can inject malware that may be able to migrate to other in-car networks such as the controller-area-network (CAN) bus which links to the vehicle’s critical systems. Software provided for dealers to interface with cars through the OBD2 port is vulnerable to reverse engineering and tampering attacks. Hackers may be able to abuse these tools to inject malicious code into the ECUs and CAN bus. Attackers can lift the cryptographic keys used, and use that to build their own rogue apps/software. Their cloned version of the original app/software may have altered functionality, and may intend to gain access to other in-car networks.
