JLR Cyberattack Halts UK Production, Uninsured £2B Hit

Jaguar Land Rover has been hit by a cyberattack since the end of August that shut IT systems, halted production and dispatch, and left UK factories closed at least until Oct. 1, forcing roughly 33,000 staff to stay home. Reports say JLR was uninsured for this attack and the disruption could cost up to £2 billion, with losses estimated at about £50 million a week—larger than JLR’s FY25 profit and likely to materially dent Tata Motors’ results given JLR’s outsized contribution to group revenue. Tata Motors’ shares fell about 4% as investors priced in delivery delays and the potential fallout. Tata Group’s TCS has deployed dozens of executives to help contain the breach and group chair Natarajan Chandrasekaran is taking weekly updates; recovery is expected to take weeks and is straining smaller suppliers. The incident underscores growing cyber risk in auto manufacturing, where prolonged IT outages translate directly into large production losses and supply-chain disruption.
