Rise in Automotive Cyber Threats Targets Connected and Autonomous Vehicle Supply Chain
What Happened — A Dark Reading analysis highlights a sharp increase in cyber‑risk exposure for modern vehicles as manufacturers integrate connectivity, over‑the‑air updates, and autonomous driving functions. Threat actors are exploiting insecure telematics, infotainment systems, and third‑party supplier code to gain footholds in the automotive ecosystem.
Why It Matters for TPRM —
- Vehicle OEMs and Tier‑1 suppliers increasingly rely on external software components, expanding the attack surface.
- Compromise of automotive systems can lead to safety‑critical failures, regulatory penalties, and brand damage that cascade to downstream partners.
- Many contracts lack explicit security clauses for OTA updates and supply‑chain hardening, creating blind spots for third‑party risk programs.
Who Is Affected — Automotive manufacturers, Tier‑1 and Tier‑2 suppliers, telematics service providers, cloud hosts supporting OTA platforms, and any enterprise that integrates vehicle data into its operations.
Recommended Actions —
- Conduct a supply‑chain risk assessment focused on automotive software vendors and OTA service providers.
- Verify that contracts include security requirements for secure boot, code signing, and vulnerability disclosure.
- Require regular penetration testing of telematics and infotainment stacks, and enforce patch‑management SLAs.
Technical Notes — Threat vectors include insecure Bluetooth/Wi‑Fi interfaces, unpatched infotainment OS vulnerabilities, and malicious code injected via third‑party libraries. No specific CVEs are cited, but the trend points to a rise in “remote code execution” and “privilege escalation” exploits in vehicle ECUs. Source: Dark Reading
