In a message to customers, M&S has advised that there is "no need for customers to take any action". CEO Stuart Machin took to the official M&S account, stating: "As we continue to manage the current cyber incident. We have written to customers today to let them know that unfortunately, some personal customer information has been taken."

Machin further assured customers by saying: "Importantly, there is no evidence that the information has been shared, and it does not include usable card or payment details, or account passwords, so there is no need for customers to take any action." Nonetheless, he hinted at recommending a precautionary step for customers the next time they log in online.

"To give customers extra peace of mind, they will be prompted to reset their password the next time they visit or log on to their M&S account," he said. "We have shared information on how to stay safe online.

"Everyone at M&S is working around the clock to get things back to normal for our customers as quickly as possible, and we are very sorry for any inconvenience they have experienced. Our stores remain open as they have throughout. Thank you for shopping with us and for your continued support, we are incredibly grateful."

A statement on the M&S website reads: "You do not need to take any action, but you might receive emails, calls or texts claiming to be from M&S when they are not, so do be cautious. We will never contact you and ask you to provide us with personal account information, like usernames, and we will never ask you to give us your password."

What has happened?

Since April 25, M&S has been unable to accept any orders through its website or app whilst it addresses the problem, yet all physical shops are still trading. M&S initially identified the issue over the Easter weekend, which caused a disturbance in contactless payments and click-and-collect offerings, and has also impacted product availability within its stores.

Operations director Jayne Wall said: "To proactively manage the incident, we immediately took steps to protect our systems and engaged leading cyber security experts. We also reported the incident to relevant government authorities and law enforcement, who we continue to work closely with."

How does it impact you and what actions should you take?

Jayne Wall advises: "You do not need to take any action, but you might receive emails, calls or texts claiming to be from MandS when they are not, so do be cautious. Remember that we will never contact you and ask you to provide us with personal account information, like usernames, and we will never ask you to give us your password."

For further reassurance, she notes: "To give you extra peace of mind, next time you visit or login to your MandS.com account on our website or app, you will also be prompted to reset your password." She adds: "We sincerely apologise for any inconvenience caused to you and all of our customers. Thank you so much for shopping with us and for your support, we never take it for granted."
