Record ransomware hits UK firms, causes billions in damage

A surge in high-profile and financially devastating cyberattacks against major UK businesses throughout 2025 has crystallized the threat as a fundamental risk to national economic stability, according to The Independent.

Incidents targeting automotive giant Jaguar Land Rover, retailer Marks & Spencer, and luxury department store Harrods underscored broad sector vulnerability, with JLR's five-week production halt alone causing an estimated £1.9 billion in national economic damage.

According to NCC Group data, global ransomware attacks reached record levels, while the UK's National Cyber Security Centre reported handling 204 "nationally significant" incidents, a sharp rise from the prior year. NCC Group CEO Mike Maddison described 2025 as a "tipping point," stressing that "cyber risk is intertwined with economic stability and business continuity."

The financial toll was severe, with M&S reporting a 324 million sales loss and the Co-op confirming a breach affecting all 6.5 million members. Governor of the Bank of England Andrew Bailey emphasized the critical need for collaborative defense, labeling cyber threats among the top risks to UK financial stability.
