Uniqlo’s owner Fast Retailing Co. has said hackers have likely gained access to at least 460,000 customer accounts.
The fashion retailer has said that nearly half a million accounts registered on the group’s Japanese Uniqlo and GU brand websites have been hacked.
In an announcement made on Monday, Fast Fashion said the hack had occurred between April 23 and May 10, potentially compromising customers personal details including their name, address, phone number, email address, date of birth, clothing measurements, part of their credit card numbers and purchase history.
It is understood that the breach was a list-based attack, with identification numbers and passwords being acquired via a previous leak from another retailer.
This type of attack occurs when customers use the same login details for different websites.
“We deeply apologize to our customers and pledge to prevent this from happening again,” the company stated, adding that although it has taken measures to black access to the affected accounts customers affected should change their passwords.
