M&S eyes full online recovery by august after cyberattack

Customer data breach and supply chain disruption hit M&S, with recovery plans now underway.
Corporate targets may face more attacks as ransomware groups retaliate against each other with increasing hostility.

Marks & Spencer (M&S) expects its full online operations to be restored within four weeks, following a cyber attack that struck in April. Speaking at the retailer’s annual general meeting, CEO Stuart Machin said the company aims to resolve the majority of the incident’s impact by August.

The cyberattack, attributed to human error, forced M&S to suspend online sales and disrupted supply chain operations, including its Castle Donington distribution centre. The breach also compromised customer personal data and is expected to result in a £300 million hit to the company’s profit.

April marked the beginning of a multi-month recovery process, with M&S confirming by May that the breach involved a supply chain partner. By June, the financial and operational damage became clear, with limited online services restored and key features like click-and-collect still unavailable.

The e-commerce platform in Great Britain is now partially operational, but services such as next-day delivery remain offline. Machin stated that recovery is progressing steadily, with the goal of full functionality within weeks.

Julius Cerniauskas, CEO of web intelligence firm Oxylabs, highlighted the growing risks of social engineering in cyber incidents. He noted that while technical defences are improving, attackers continue to exploit human vulnerabilities to gain access.

Cerniauskas described the planned recovery timeline as a ‘solid achievement’ but warned that long-term reputational effects could persist. ‘It’s not a question of if you’ll be targeted – but when,’ he said, urging firms to bolster both human and technical resilience.

Executive pay may also be impacted by the incident. According to the Evening Standard, chairman Archie Norman said incentive compensation would reflect any related performance shortfalls. Norman added that systems are gradually returning online and progress is being made each week.
