Fast Retailing Co., parent company of Uniqlo and Asia's largest retailer, confirms data belonging to 461,091 people was compromised in a cyberattack on its Uniqlo and GU shopping websites.

Officials say the breach took place between April 23 and May 10, 2019, when it was confirmed, as reported in a statement on Fast Retailing's website. An investigation began when customers reported strange account activity — for example, notice of registration information changes. So far, officials have learned this is a "list-type attack" on the firm's Japanese websites, meaning intruders reused credentials that were also used on, and stolen from, other sites.

Compromised data includes: full name, physical and email address, phone number, gender, birth date, purchase history, and partial credit card numbers. The company reports credit card numbers are hidden except for the first and last four digits; CVV numbers are not stored.

Fast Retailing has invalidated the account passwords of affected users and notified them to reset their passwords. Read more details here.
