TOKYO (Kyodo) -- Fast Retailing Co. said Tuesday personal information from 461,091 customer accounts for the shopping websites of its Uniqlo and GU brands may have been leaked through unauthorized access.
The operator of the two fast-fashion brands said the two online store websites were hacked between April 23 and May 10 and customers' names, addresses, phone numbers and credit card data may have been leaked.
There have been no reports of information being used by a third party, the company said.
Fast Retailing has taken measures to block the unauthorized access and invalidate the passwords of the affected accounts. It also asked all affected customers to reset their passwords to access the company's online stores.
The casual clothing store operator said identification numbers and passwords previously leaked from other website operators may have been used in the unauthorized access.
"We deeply apologize to our customers and pledge to prevent this from happening again," said the company in a statement.
