The luxury department store Harrods says it is the last retailer to have been targeted by a cyber attack.
The company said it had “restricted Internet access to our sites” after trying to access its systems.
This comes the day after the cooperative, which closed the parties of its computer systems to push a hacking, while Marks & Spencer continues to face a cyber attack that cost him millions of books in loss of sales.
Harrods said his flagship store had remained open and that he continues to operate his online sales.
Customers are invited to “do nothing different at this stage”.
A Harrods declaration said: “We recently underwent attempts to obtain unauthorized access to some of our systems.
“Our experienced computer security team immediately took proactive measures to ensure systems security and, therefore, we have limited internet access to our sites today.
“Currently, all the sites, including our Knightsbridge store, beauty stores and airport stores, remain open to accommodate customers. Customers can also continue to shop via Harrods.com.
“We do not ask our customers to do anything differently at this stage and we will continue to provide updates if necessary.”
It occurs when M&S saw its operations seriously hampered by a cyber attack that the company revealed last week.
Customers are still unable to place orders online and the shelves have remained empty in certain stores.
The police investigate.
Meanwhile, the cooperative said on Wednesday that it had closed certain parts of its computer systems in response to the pirates who were trying to access.
On Thursday, it appeared that the staff was ordered to keep their cameras during remote work meetings and to check all the participants.
Experts say it indicates that the company suspects that hackers can hide in calls.
We do not know if the three incidents are connected.
But it is believed that M&S was attacked with ransomware.
This is a type of malware used to blur important data or files after accessing computer systems, locking essentially unless a ransom is paid.
Security experts told the BBC on Tuesday that a ransomware group called “DragonForce” was behind the attack.
The retailer did not comment. The cooperative did not give any details on the nature of the cyber attack against it.
