The spokesperson said: “We are working closely with our suppliers to restock our stores.
“We have switched all our orders back to the normal supply processes and systems.”
The Co-op is understood to have told suppliers that there may be some “volatility” in ordering as the systems return to normal functioning.
Customers warned of data breach
The Co-op had already written to customers warning that “limited” customer data had been accessed in the cyber attack.
It believes data that has been extracted includes members’ names, contact details and dates of birth, but not passwords or credit card details.
Customer membership cards and apps remain active, and customers are urged to be cautious of suspicious emails or phone calls and never share personal or banking information with anyone who purports to be from the Co-op unless they are sure it is a legitimate request.
The Co-op is Group is not the only major retailer to fall victim to hackers in recent weeks. M&S is still unable to sell items online after a major hack and has written to customers to say data has been accessed. M&S shoppers will be prompted to change their passwords when they log in again after the attack on 25 April.
