- Cyber Monitoring Center rates JLR incident as Level 3 (M&S was Level 2)
- Wholesale sales down 24.2% year-on-year, Jaguar transforms
- The attack cost around £1.9 billion (of which £1.5 billion came from government loans).
The Jaguar Land Rover (JLR) hack in August 2025 is estimated to have cost £1.9 billion ($2.6 billion), according to an official report.
A Cyber Monitoring Center report described the incident as “the most economically damaging cyber event to hit the UK”, ranking its effects higher than those of the incident affecting M&S earlier in 2025.
More than 5,000 UK-related organizations were affected, including suppliers and dealers, widening the impact of the breach.
Effects of the JLR cyberattack
During the lockdown, which lasted for around 5-6 weeks, JLR lost around £50 million per week. It then secured a £1.5 billion ($2 billion) government loan to support both its core operations and its suppliers.
Although the systems are back operational to some extent, it could take until early 2026 before JLR reaches a full recovery state.
JLR’s factories in Solihull, Halewood and Wolverhampton were affected, impacting the company’s daily production of 1,000 cars.
As well as describing the JLR attack as the “most economically damaging” event in UK history, the Cyber Monitoring Center also classified the breach as a level three incident, with five being the highest, suggesting that potential future attacks could be even more damaging.
To put this into perspective, the attacks on M&S, Co-op and Harrods earlier this year reached level two, with a total cost estimated at between £270 million and £440 million.
However, JLR has still not revealed what type of attack it faced, nor whether or not it paid a ransom (which is not included in the estimate above).
On October 7, JLR noted a 24.2% year-over-year decline in wholesale sales. “It has been a difficult quarter for JLR. During the first two months, our performance has been robust and in line with our expectations,” explained CEO Adrian Mardell.
The cyber incident came just months after the company confirmed it would end Jaguar sales amid the brand’s reinvention.
“We know there is still much to do, but our recovery is firmly underway,” Mardell added.
