Getty ImagesThe luxury department store Harrods says it is the latest retailer to have been targeted by a cyber attack.
The firm said it had restricted access to its websites following an attempt to gain access to its systems.
It comes the day after the Co-op shut down parts of its IT systems to fend off a hack, while Marks & Spencer continues to deal with a cyber attack that has cost it millions of pounds in lost sales.
Harrods said its flagship store remained open, and it continues to operate its online sales.
Customers are not being asked to not "do anything differently at this point".
A statement from Harrods read: "We recently experienced attempts to gain unauthorised access to some of our systems.
"Our seasoned IT security team immediately took proactive steps to keep systems safe and as a result we have restricted internet access at our sites today.
"Currently all sites including our Knightsbridge store, H beauty stores and airport stores remain open to welcome customers. Customers can also continue to shop via harrods.com.
"We are not asking our customers to do anything differently at this point and we will continue to provide updates as necessary."
