Summary

Hide ▲

In 2025, ransomware became the fastest-growing and most disruptive threat to automotive carmakers, accounting for 44% of attacks and more than doubling over the year. The trend raises sector-wide disruption risk because automakers depend on connected vehicle platforms, OTA update mechanisms, cloud services, and third-party suppliers. Low tolerance for downtime makes the sector especially vulnerable to production stoppages and supply-chain knock-on effects.

    Halcyon report on 2025 automotive carmaker ransomware surge

    Technical Analysis Update

    Halcyon says ransomware became the fastest-growing and most disruptive cyber threat facing automotive carmakers in 2025, accounting for 44% of attacks and more than doubling over the year. The report links the risk to connected vehicle platforms, over-the-air (OTA) update mechanisms, cloud-based environments, and privileged third-party supplier access, and recommends patching VPNs, RDP endpoints and ERP systems, deploying phishing-resistant MFA, hardening EDR, maintaining immutable offline backups, and monitoring third-party breaches.
