As vehicles become increasingly reliant on software, secure and functional Hardware Security Modules (HSMs) are paramount. Unknown vulnerabilities in your automotive software can pose a significant threat to your products and business by putting you at risk of coding errors or insecure configurations, which can be exploited by malicious actors or lead to consequential failures.

Therefore, continuously testing HMS modules is crucial to ensure that functional and security bugs are found long before they make it anywhere near a finished product. In the automotive industry, where undiscovered issues can put human lives at risk or lead to costly callbacks, thorough testing is paramount. Considering the pivotal role of HSMs as the root of trust in communication within a car, if an attacker can take over an HSM, the consequences are dire. Such a breach not only jeopardizes data integrity but also poses a significant threat to vehicle safety and passenger security. Hence, rigorous testing remains the primary defense against these potentially devastating breaches.

At Code Intelligence, we've repeatedly discovered various security issues in HSMs throughout the automotive industry that had slipped through multiple “traditional”, ranging from remote code executions and buffer overflows to heap use after free and segmentation fault.
