Key Takeaways
- Tata Motors-owned JLR cyberattack cost UK economy £1.9 billion
- Over 5,000 UK businesses affected by the supply chain disruption
- Production remains below pre-hack levels after complete September shutdown
A cyberattack on Tata Motors-owned Jaguar Land Rover has been declared the most damaging cyber event in UK history, costing the economy £1.9 billion and affecting over 5,000 businesses.
The Cyber Monitoring Centre (CMC) classified JLR’s “malicious cyber incident” as a Category 3 systemic event on its five-point scale.
Massive Financial Impact
“The CMC model estimates the event caused a UK financial impact of 1.9 billion pounds and affected over 5,000 UK organisations,” the centre stated.
CMC noted the loss range could be between £1.6 billion to £2.1 billion, potentially increasing if operational technology suffered significant damage or production recovery faces unexpected delays.
“This estimate reflects the substantial disruption to JLR’s manufacturing, to its multi-tier manufacturing supply chain, and to downstream organisations including dealerships,” the statement added.
Ongoing Recovery Efforts
JLR, which hasn’t directly commented on the CMC data, confirmed it’s restoring stalled operations in phases. The late August cyberattack forced complete production shutdowns through September across JLR’s global operations.
The automotive major has yet to fully resume its pre-hack manufacturing schedule, indicating continues.
