M&S had run a cyberattack simulation final yr he mentioned, so “was prepared”.

“We had been capable of reply shortly and take the proper actions instantly,” he mentioned. “We knew who to name and learn how to put the enterprise continuity plan into motion.”

The hackers used social engineering strategies, that means they relied on human error or misjudgement, fairly than a purely technological loophole.

They gained entry to M&S’s system through a “third celebration” – an organization working alongside the retailer – fairly than accessing methods immediately.

M&S reported a 22% rise in revenue earlier than tax and different prices to £875m, whereas gross sales rose 6.1% to £13.9bn, with rising meals gross sales taking the lead.

Lucy Rumbold, fairness analysis analyst at Quilter Cheviot, mentioned it could be “an extended slog” for M&S to get again to the place it was.

“However given the sturdy efficiency of late and supplied the assault could be wholly eradicated, the enterprise ought to get there,” she mentioned.
