In April 2019, UNIQLO Japan's online store experienced a credential stuffing attack that compromised over 460,000 customer accounts. The breach exposed personal and financial data including names, addresses, contact information, purchase histories, and partial credit card details. The parent company responded by disabling affected credentials, initiating password resets, and notifying impacted customers. The incident was attributed to automated attacks leveraging stolen credentials from third-party sources. This event highlighted the prevalence of credential reuse and the limited adoption of two-factor authentication in the retail sector. It underscored a notable competency gap in cybersecurity defenses for the organization. UNIQLO Japan remains a subsidiary of Fast Retailing, with its headquarters located in Japan. It continues to operate as a key component of the group's global apparel portfolio.
