British retailer Marks & Spencer estimates that a cyberattack that stopped it from processing online orders and left store shelves empty will cost it about 300 million pounds, or $400 million.

The action of hackers against their online network during Easter will cost them the equivalent of more than half of the 2024 operating profit. Cyberattacks are no longer just disruptions to activity or reasons for reputational damage.

When will the retailer be back to normal? - The retailer has said a recent cyber attack will cost the firm around £300 million.
