British Retailer Says Cyberattack Will Cost It $400 Million

Marks & Spencer, one of Britain’s largest retailers, said that disruption from a “highly sophisticated” cyberattack that crippled operations over the last month was expected to linger until July and would cost the company about 300 million pounds ($400 million) in lost profits this year. The breach, which emerged over the Easter weekend, has been costing the company millions of pounds a day after it had to pause online orders, staff had to resort to manual processes and food waste piled up.
