Jaguar Land Rover’s big cyberattack in 2025 hit hard—£1.9 billion lost, factories closed for six weeks, and the whole supply chain left exposed.
Back in August 2025, Jaguar Land Rover—Britain’s top carmaker—got slammed by a cyberattack that forced them to shut down all production. We’re talking about nearly six weeks with no cars rolling off the line and a financial hit that added up to £1.9 billion. That’s probably the most expensive cyberattack the UK’s ever seen. It’s a clear sign: even the biggest names aren’t safe, and manufacturing needs much stronger cybersecurity.
Financial Fallout
JLR lost about £50 million every week the factories sat idle. The crisis got so bad, the UK government had to step in with a £1.5 billion loan guarantee just to keep JLR’s suppliers afloat.
How Long It Took to Recover
The attack froze everything at JLR’s three UK plants. Usually, those factories crank out about a thousand cars a day, but for almost six weeks—nothing. Early October finally brought a partial restart, with the most crucial operations coming online first. Full production didn’t get going again until later that month. Even then, experts figured it’d be early 2026 before JLR got back to business as usual.
What Happened to the Supply Chain
JLR’s shutdown didn’t just hurt them. Over 5,000 suppliers and dealerships got caught up in the mess. With no orders coming in, smaller suppliers were on the edge of going under. JLR scrambled to help, paying suppliers upfront and speeding up payments to keep money moving. The government’s loan guarantee gave another lifeline, keeping the whole supply chain from falling apart. This attack didn’t just hit one company—it shook the whole industry, and everyone felt it.
