Automakers urged to strengthen cybersecurity after JLR shutdown – CBT News
While no system is completely hack-proof, proactive cybersecurity can avert large-scale shutdowns like the one JLR experienced.
On the Dash:
- Jaguar Land Rover’s 40-day cyberattack shutdown cost an estimated $2.67 billion and highlights risks for automakers.
- Legacy systems and linked IT-OT networks create vulnerabilities that require aggressive monitoring and proactive cybersecurity.
- Balancing uninterrupted production with security measures is essential to prevent costly, industry-wide disruptions.
Jaguar Land Rover’s nearly 40-day global factory shutdown due to a cyberattack has highlighted vulnerabilities in automotive production networks and cost the company an estimated £2 billion ($2.67 billion) in lost revenue. Security experts warn that automakers worldwide must assess and strengthen their IT and operational technology systems to prevent similar catastrophic disruptions.
The incident has prompted boardrooms to rethink how legacy systems, often decades old, are integrated into modern vehicle production. The convergence of information technology (IT), which runs on office networks, and operational technology (OT), which manages factory floor operations, creates significant risk. Hackers can exploit these links to infiltrate production systems through a single network connection.

Cybersecurity specialists from Upstream and Aeris told WardsAuto that they recommend automakers adopt aggressive monitoring systems capable of detecting anomalies in real time and mitigating threats before they affect mission-critical production processes. Without such safeguards, minor disruptions can escalate into full-scale production stoppages, affecting both revenue and delivery schedules.
The challenge lies in balancing operational efficiency with cybersecurity. Factory managers aim to maintain uninterrupted production, while IT departments focus on preventing breaches. Modern IP-connected systems allow engineers to remotely adjust production parameters, boosting efficiency but also creating potential points of vulnerability. Experts stress that integrating security monitoring across all networks, rather than treating cybersecurity as an afterthought, is essential for resilience.
While no system is completely hack-proof, lessons can be learned from Tesla’s approach, which integrates cybersecurity into computer architecture from the ground up. Specialists say automakers must prepare for occasional minor interruptions as a trade-off to avoid large-scale shutdowns like the one JLR experienced.
The JLR incident underscores the importance of proactive cybersecurity in an increasingly connected automotive industry. As production processes become more reliant on digital systems, the potential cost of inaction continues to rise, making cyber resilience a critical priority for automakers and their boards.
