M&S website still offline after cyberattack

Hackers stole personal data, including names and addresses, from M&S systems during the Easter weekend, forcing the firm to halt online orders.

M&S says a cyberattack caused by human error may cost £300 million, with its website still down and recovery expected to last until July.

Marks & Spencer’s website remains offline as the retailer continues recovering from a damaging cyberattack that struck over the Easter weekend.

The company confirmed the incident was caused by human error and may cost up to £300 million. Chief executive Stuart Machin warned the disruption could last until July.

Customers visiting the site are currently met with a message stating it is undergoing updates. While some have speculated the downtime is due to routine maintenance, the ongoing issues follow a major breach that saw hackers steal personal data such as names, email addresses and birthdates.

The firm has paused online orders, and store shelves were reportedly left empty in the aftermath.

Despite the disruption, M&S posted a strong financial performance this week, reporting a better-than-expected £875.5 million adjusted pre-tax profit for the year to March—an increase of over 22 per cent. The company has yet to comment further on the website outage.

Experts say the prolonged recovery likely reflects the scale of the damage to M&S’s core infrastructure.

Technology director Robert Cottrill described the company’s cautious approach as essential, noting that rushing to restore systems without full security checks could risk a second compromise. He stressed that cyber resilience must be considered a boardroom priority, especially for complex global operations.
