Yes24 Leak Exposes Personal Data of 120,000 Customers

Yes24

A credential-stuffing attack led to the unauthorized exposure of 120,000 customer profiles.

In June 2024, online bookstore and ticketing giant Yes24 disclosed a data leak affecting approximately 120,000 users. Attackers gained access to names, birth dates, email addresses, and phone numbers. The company faced criticism for slow detection times, as the unauthorized access persisted for several days before being mitigated.
