JD Sports says it's been the target of a cyber attack.
The retailer says there's been unauthorised access to customer data for some online orders placed between November 2018 and October 2020.
According to Reuters, the group said; "the affected data was "limited", as it does not hold full payment card data and did not believe account passwords were accessed.
"The attack related to online orders placed for the JD, Size?, Millets, Blacks, Scotts and MilletSport brands between November 2018 and October 2020."
They continued to say: "JD Sports said information that may have been accessed consisted of the name, billing address, delivery address, email address, phone number, order details and the final four digits of payment cards of about 10 million customers."
