A cyberattack on Jaguar Land Rover (JLR) has caused an estimated £1.9 billion ($2.55 billion) in losses to the UK economy, marking one of the most damaging cyber incidents in the nation’s history, according to the Cyber Monitoring Centre (CMC).
The CMC report found that the breach, which occurred in August, disrupted more than 5,000 organisations, including suppliers and dealerships. Most losses came from halted vehicle production, with JLR forced into a six-week shutdown across its three UK factories that collectively produce around 1,000 cars daily.
The report warned that total costs could rise if JLR’s output does not quickly return to pre-attack levels. Analysts estimated the company lost roughly £50 million per week during the downtime.
In response, the British government approved a £1.5 billion loan guarantee to support the automaker and its supplier network. The CMC, which ranks incidents based on systemic risk, classified the breach as a Category 3 event out of five — denoting major industrial disruption.
“This incident appears to be the most economically damaging cyber event to hit the UK,” the CMC said, noting that losses extended throughout JLR’s multi-tier manufacturing supply chain and downstream partners.
The attack follows a series of high-profile UK cyber incidents in 2025, including one at Marks & Spencer, which reportedly lost £300 million ($400 million) after its online operations were knocked offline for two months.
JLR declined to comment, while the CMC emphasized that the event highlights the systemic risk cyberattacks pose to Britain’s manufacturing sector and broader economy.
