Jaguar Land Rover (JLR) experienced a substantial cyberattack that forced a prolonged shutdown of its manufacturing operations, causing massive financial losses and operational disruption. The company initially claimed no customer data was stolen, but later retracted that assertion as the scale of the breach became clearer. Estimates suggest JLR lost hundreds of millions of dollars per week, with the total damage potentially ranging between $1.7 billion and $2.4 billion. The disruption extended well beyond IT systems—factory lines were idled, supply chains were impacted, and normal business processes ground to a halt.

Investigations suggest the attackers had lingering access from a prior breach earlier in the year, which allowed them to strike at a strategically critical moment (“New Plate Day,” a high-volume sales period). Poor internal segmentation enabled attackers to move from enterprise networks into operational technology systems, amplifying the damage. The incident serves as a stark reminder that even large, well-resourced organizations can be debilitated by cyberattacks—especially when persistence, timing, and weak defense layers are exploited in concert.
