PChome E-commerce Platform Bibian Confirms Major Personal Data Leak

Bibian, a Japanese cross-border e-commerce platform under Taiwan's PChome Group, has confirmed a significant personal data breach. Numerous members have reported receiving fraudulent emails impersonating the official platform, alarming users with the detailed personal information included in the messages.

The scam emails typically claim a "system detected a duplicate order" and urge recipients to contact customer service to cancel if the transaction was unauthorized, guiding them towards phishing links. What has particularly angered users is the accuracy of the disclosed personal data, which includes full names, phone numbers, home addresses, order details, and even national identification numbers. Some users noted that the emails even referenced items purchased years ago on Bibian, indicating a substantial leak of historical data.

The name, phone number, address, and ID number were all exposed, it's truly outrageous.

In response to the incident, Bibian issued an apology to affected members, admitting that the leaked data originated from its systems. The company stated it has collaborated with a third-party cybersecurity team to investigate the breach, identify vulnerabilities, and implement necessary security enhancements. Bibian clarified that the breach primarily impacted members using its personal shopping and Bibian Japanese goods services, with its Japanese bidding service remaining unaffected.

Bibian further explained that the leaked information likely includes basic contact details and order-related data. The platform has promised to announce details regarding compensation for affected members on June 18, 2026. In the meantime, Bibian is urging its members to exercise caution and avoid clicking on links or providing personal information in unsolicited emails, advising them to log in directly to the official website for order inquiries.
