Jaguar Land Rover's cyberattack halted production, costing £50M weekly and risking £2B in losses.

Tata Motors shares fell 3-4% on September 25, 2025, after its UK subsidiary Jaguar Land Rover faced a major cyberattack that halted production across three factories until at least October 1, causing weekly losses of about £50 million. The attack, linked to the group Scattered Lapsus$ Hunters, disrupted operations and affected 33,000 employees, with JLR potentially facing up to £2 billion in losses—exceeding its prior year’s profit. The company reportedly lacked cyber insurance, despite ongoing negotiations with broker Lockton, worsening financial exposure. As JLR contributes about 70% of Tata Motors’ revenue, the incident significantly impacted investor confidence, pushing the stock below key moving averages and lowering its value by nearly 6% over five days.
