TL;DR: Most automotive attacks in 2024 were remotely executed, and many could scale across fleets because common software and architectures are reused, according to RunSafe Security. Vehicles therefore need security decisions that treat code, update paths and supplier inputs as safety-relevant controls.
Editorial analysis by NHI Mgmt Group, based on content published by RunSafe Security: “Automotive Software Security: 5 Ways to Secure Modern SDVs”.
Key questions
Q: Why does infotainment often become the first step in a vehicle attack chain?
A: Infotainment often becomes the first step because it is exposed to external inputs such as Bluetooth, USB, Wi-Fi, mobile apps and media files, then connected to vehicle networks.
Q: What is the best way to secure over-the-air vehicle updates?
A: The best way to secure over-the-air vehicle updates is with strong signing, validation of the update package, and a secure delivery path that enforces integrity, authenticity and anti-rollback checks.
Q: How do memory safety flaws turn into vehicle compromise in SDVs?
A: Memory safety flaws such as buffer overflows can let an attacker corrupt execution flow, run arbitrary code or escalate privileges inside embedded vehicle software.
Practitioner guidance
- Define software trust boundaries across the vehicle stack Map which components can influence each other, then enforce isolation between infotainment, telematics, ECUs and ADAS so a compromise in one zone cannot automatically reach another.
- Introduce runtime protections for memory-unsafe components Apply build-time hardening and runtime memory protection to code paths that remain in C or C++ so exploitability is reduced without waiting for a full rewrite.
- Govern OTA updates as a security control Require signing, validation, safe rollback and telemetry for every update path so patching does not become a new attack surface.
Bottom line: Software-defined vehicles expand the security problem from isolated components to a lifecycle-wide governance issue spanning code, suppliers and updates.

Automotive software security is now a lifecycle governance problem, not a feature-level hardening task. SDVs compress safety, connectivity and monetisation into one software stack, which means security failures can propagate across products, updates and suppliers. That changes the governance question from whether a component is hardened to whether the vehicle's software estate can be understood, controlled and updated across its entire lifecycle. Practitioners should treat build, release and post-sale operations as one security domain.
A question worth separating out:
Q: How should suppliers prove software provenance for automotive systems?
A: Suppliers should prove software provenance with a software bill of materials, signed build artefacts, traceable source control, and controlled release records that link each component to its origin and version. That evidence helps buyers verify what code is present, which third-party libraries were used, and whether the delivered software matches the approved build.
