M&S faces major loss due to cyber attack

Marks and Spencer is bracing for financial fallout from a cyber attack, which is forecasted to cost the company around £4 million daily in lost sales. The company will share its financial performance on May 21. While it is expected to post an increase in total group sales to approximately £13.8 billion, the full impact of the cyber attack will not be reflected in these figures, as they cover the year ending March 31. The fashion segment may suffer particularly during this critical retail period, as online orders remain suspended. Cybersecurity experts note a shift in focus from UK to US targets by the attackers, known as Scattered Spider.

"Although the annual numbers won’t show the effect, some guidance for the year ahead is expected, and it’s likely to be very cautious indeed."

Susannah Streeter from Hargreaves Lansdown emphasizes the cautious outlook for M&S post-breach.

"Scattered Spider members in the UK are facilitating and contributing to intrusions."

Charles Carmakal, CTO at Google's Mandiant, discusses the active role of UK-based cybercriminals in recent attacks.

The situation highlights how vulnerable retailers are to cyber threats, especially during peak trading times. Marks and Spencer’s reported sales growth may seem positive, but this is overshadowed by potential losses from the breach. As retailers increasingly rely on online sales, incidents like this can cause lasting damage to brand reputation and customer trust. The cautious guidance expected from M&S could reflect deeper concerns about future earnings, emphasizing the need for enhanced security measures in the retail sector.
