Marks & Spencer cyberattack highlights growing cybersecurity risks for retailers

Marks & Spencer (M&S) is grappling with the aftermath of a significant cyberattack that began over the Easter weekend, causing widespread disruption to its operations and impacting its market valuation.

The incident forced the retailer to suspend online orders for clothing and homeware, affecting both its website and app. Customers experienced issues with contactless payments, click-and-collect services, and the Sparks loyalty programme. In response, M&S instructed approximately 200 agency staff at its Castle Donington distribution centre to stay home due to reduced order volumes.

While M&S has not confirmed the exact nature of the cyberattack, cybersecurity experts suggest it bears the hallmarks of a ransomware incident. The company has reported the breach to the Information Commissioner’s Office and is collaborating with the National Cyber Security Centre to investigate and mitigate the issue.

Financially, the cyberattack has had a notable impact. M&S’s share price has declined by approximately 7% since the incident was disclosed, equating to a loss of nearly £700 million in market capitalisation. This setback comes as the company was showing positive momentum under CEO Stuart Machin, with improved sales and a return to the FTSE 100 index.

Despite the disruptions, M&S has assured customers that their personal data remains secure and that it is safe to shop in stores. The company continues to work diligently to restore its online services and has apologised for the inconvenience caused.

This incident highlights the growing cybersecurity challenges faced by retailers, especially those with significant online operations and hybrid working models. M&S had previously acknowledged in its annual report that the shift to hybrid work increased its vulnerability to cyber threats.
