The start of September was expected to be a peak period for Jaguar Land Rover (JLR), with the release of new 75 series number plates typically driving a surge in demand. Instead, a major cyber attack at the end of August forced a shutdown of JLR’s production lines at its factories in Solihull, Halewood, and Wolverhampton. Staff who arrived for early shifts were sent home, and although a phased resumption of manufacturing is now underway, output is expected to take several weeks to return to normal levels. Analysts estimate JLR’s losses from the shutdown have been at least £50 million per week. For a company that reported a £2.5 billion profit last year and is owned by India’s Tata Group, the blow is significant but not crippling. The UK government has pledged a $2 billion loan guarantee to support JLR’s supply chain through the crisis. Key systems that manage global parts supply and vehicle wholesaling have been restored, alongside improvements to invoice processing.

This attack on JLR, however, is part of a wider pattern of cyber assaults hitting UK businesses in 2025. Retail giants Marks & Spencer and the Co-op have also faced debilitating hacks this year, costing hundreds of millions of pounds collectively. Marks & Spencer suffered a ransomware attack via a third-party contractor during Easter, disrupting contactless payments and online shopping—an estimated third of its business. The Co-op endured a similar ransomware extortion attempt by the same hacking group but managed to limit damage by quickly shutting down its IT networks. These incidents illustrate a growing trend where hackers, often English-speaking younger criminals leasing ransomware tools from Russian-speaking cybercriminals, target prominent companies both for financial gain and to build reputations within the hacking community.

Such attacks are particularly damaging where companies rely on tightly coordinated supply chains. JLR’s just-in-time delivery system, designed to minimise inventory costs by ordering parts exactly when needed, proved highly vulnerable. The shutdown affected thousands of suppliers ranging from multinational giants like Bosch to small firms dependent solely on JLR contracts—some facing collapse after weeks without sales but with ongoing costs. Industry experts warn that bankruptcies in the supplier pyramid could deal lasting damage to the UK’s advanced engineering sector. Marks & Spencer’s similarly intricate supply chain for fresh produce also suffered from these disruptions, highlighting how lean management models in automotive, food, aerospace, and electronics industries can amplify the impacts of cyber outages.

Industry economists and former manufacturing executives suggest that such lean production models might need reevaluation to build resilience against future cyber ‘black swan’ events—unforeseen crises with major consequences. Nonetheless, the high cost of maintaining larger inventories or altering supply chain logistics means businesses are reluctant to abandon just-in-time management on economic grounds, and regulators face challenges in enforcing such changes.

Beyond manufacturing and retail, the threat landscape extends to critical infrastructure and services. In a recent episode, ransomware disrupted airport systems across Europe, including London Heathrow, causing flight cancellations and widespread delays. Experts warn that a successful attack on financial services or energy provision could have catastrophic cascading effects, potentially costing hundreds of billions. Financial sectors benefit from stringent cyber regulations, but energy grids remain a locus of concern. A 2015 Lloyds Bank study modelled that a hypothetical cyberattack on the US power grid could cause economic losses exceeding $1 trillion (£742 billion). Although some analysts believe the UK power grid has spare capacity to absorb cyber shocks, the broad lack of urgency toward robust cyber security measures remains worrying.

Reports indicate that UK businesses and organisations, from major corporations to charities and SMEs, are collectively underestimating the financial toll of IT outages, with median costs running into millions annually. Many firms lack comprehensive tracking of outage-related expenses, and rely on fragmented tools that impede full visibility of IT systems. However, AI-powered monitoring is gaining ground as a method to improve observability, shorten downtime, and boost productivity. Despite progress, a significant share of UK organisations still fails to measure the return on investment in these advanced monitoring solutions. At the same time, emerging threats such as malicious bots driven by artificial intelligence are escalating rapidly. UK organisations rank among the worst globally in protecting against bot attacks, with a recent report showing only 1.8% of major UK domains fully safeguarded—a decline compared to previous years. Traditional static defence measures no longer suffice against AI-enabled bots that mimic human behaviour to circumvent security controls.

The vulnerability of IT ecosystems is further emphasised by incidents involving third-party providers. Harrods reported a breach resulting in the theft of 430,000 customer records via a third-party vendor. While passwords and payment data remained secure, the incident underscores growing concerns about weak links in supply chain cybersecurity. Similarly, Japanese brewing giant Asahi experienced a cyber attack that halted production at up to 30 plants, exposing the operational fragility of complex manufacturing networks. These high-profile breaches, among others, demonstrate that the threat landscape transcends borders and industries, pressuring businesses globally to bolster cyber resilience.

Experts like Jamie MacColl of the Royal United Services Institute argue that the current wave of cyber attacks represents a “cumulative effect of a kind of inaction” from both the UK government and businesses over the past 15 years. Though a Cyber Security and Resilience bill was announced last year, its progress through Parliament has been slow. Meanwhile, official warnings about the rising risks of AI-enhanced cyber threats spotlight an accelerating divide between organisations capable of keeping pace with evolving threats and those falling behind. MacColl particularly fears unknown single points of failure in the economy—companies providing essential but under-recognised services without proper regulatory oversight—could become targets whose disruption triggers wider economic fallout.

The persistent rise in cyber attacks reveals systemic weaknesses in UK industry and infrastructure. As businesses juggle financial costs with operational imperatives, and governments grapple with enforcement and policy, the pressing need for integrated, adaptive cybersecurity strategies has never been clearer. Without decisive action, the economic and societal repercussions of cyber incidents are poised to deepen, threatening not just individual companies but entire sectors and the broader economy.
