Catastrophic cyber assaults lead to £1bn losses for Marks & Spencer
High Street titan Marks & Spencer is still reeling from the devastating cyber attack that occured back in April 2025. The digital assault has left the retail giant grappling with a staggering loss of over £1billion in their market value.
Yesterday, the stock plummeted another 4.7%, accumulating a total loss of 12% since the hacking incident at Easter. The misfortune has left M&S with a market capitalisation of £7.4billion as of last night.
The recent drop in share price comes as analysts at Deutsche Bank estimate that the crisis is costing the company £15million in lost profits per week, with a total loss of £30million so far.
As the retailer grapples with the aftermath, experts warn that the costs from a cyber attack often extend beyond the initial financial hit. These costs include lost business and fines, should sensitive consumer data be compromised, as well as irreparable damage to the reputation.
The disruption, which led to empty shelves and service disruptions in M&S stores, could persist for weeks. The company was attacked by the Scattered Spider hacking group over Easter and had to cease taking clothing and home orders through its website on April 25.
