Mr Machin mentioned his staff had noticed “suspicious exercise” throughout the important thing vacation weekend.

M&S had run a cyberattack simulation final 12 months he mentioned, so “was prepared”.

“We have been capable of reply rapidly and take the appropriate actions instantly,” he mentioned. “We knew who to name and how you can put the enterprise continuity plan into motion.”

The hackers used social engineering methods, which means they relied on human error or misjudgement, slightly than a purely technological loophole.

They gained entry to M&S’s system by way of a “third occasion” – an organization working alongside the retailer – slightly than accessing techniques straight.

The technique had put M&S in it “finest monetary well being for practically 30 years” Mr Machin mentioned, delivering outcomes for the monetary 12 months ending in March simply earlier than the hack disrupted companies on the finish of April.

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 will be “an extended slog” for M&S to get again to the place it was.

“However given the robust efficiency of late and offered the assault might be wholly eradicated, the enterprise ought to get there,” she mentioned.
