What major issue did British companies face in May 2025?

In early May 2025, a series of cyberattacks disrupted operations at several major British companies, including Marks & Spencer, Co-op, and WHSmith.
A hacker group known as DragonForce claimed responsibility, breaching systems and leaking customer data on the dark web.
The attacks targeted payment systems, employee records, and delivery infrastructure, causing widespread delays and customer backlash.
According to The Times and BBC, authorities are investigating potential links to international cybercrime networks. Some experts warn this may be part of a larger trend of retail-sector targeting in the UK and Europe.
