Mumbai, Sept. 25, 2025 — Tata Motors came under pressure in the markets on Thursday after news broke that its British luxury subsidiary, Jaguar Land Rover (JLR), had suffered a major cyberattack. Shares of Tata Motors tumbled nearly 4 percent on the Bombay Stock Exchange, hitting an intraday low of ₹655.30.
Potential Loss Exceeds ₹21,000 Crore
According to a Financial Times report, the attack could inflict losses of ₹21,000 crore (2 billion pounds) on JLR. That figure would surpass the company’s ₹18,900 crore (1.8 billion pounds) profit after tax in the last fiscal year.
The company had been in talks to secure cyberattack insurance but was unable to finalize an agreement before the breach occurred, leaving it exposed to significant financial damage.

Production Halted, Weekly Losses of ₹560 Crore
JLR initially suspended production until September 24, but the shutdown has now been extended to October 1. While the company has not issued an official estimate of damages, media reports suggest it is losing about ₹560 crore (50 million pounds) each week as operations remain paralyzed.
Roughly 33,000 employees have been instructed to stay home until the company’s IT systems and production lines are fully restored.
Tata Motors Faces Ripple Effects
JLR is central to Tata Motors’ performance, contributing nearly 70 percent of the company’s overall revenue. News of the cyberattack immediately weighed on investor sentiment, raising concerns about Tata Motors’ near-term earnings.
Analysts Warn of Deeper Vulnerabilities
Industry analysts say the attack exposes broader structural risks in the auto sector.
“Automobile companies are increasingly reliant on digital networks and software. Weak security measures can disrupt not just production, but profitability across the value chain,” said Rajat Agarwal, an auto sector analyst.
A Cybercrime Expert’s View
Cybercrime expert and former Indian Police Service officer Professor Triveni Singh said the incident underscored the far-reaching economic consequences of cyberattacks.
“This is not just an IT issue but a matter of national and global economic security. When a multinational company’s production halts, the ripple effects are felt across supply chains and financial markets. The JLR case demonstrates why large corporations can no longer delay investment in cyber insurance and resilient IT infrastructure.”
He added:
“Today’s cybercriminals are as organized and resourceful as traditional crime syndicates. For industries worldwide, including India, cyber security must be seen not as a technical function but as a core element of corporate governance.”
Broader Implications
The attack comes at a time when the global auto industry is accelerating investments in electric and connected vehicles. Experts say the crisis highlights the urgent need for automakers to bolster cyber defenses and make cyber insurance and digital infrastructure resilience a strategic priority.
The JLR breach, analysts note, could dent Tata Motors’ balance sheet in the short term. More importantly, it serves as a stark warning to the global auto sector that in the digital age, cyber risk is as serious as traditional business risk.
