Yes24

Yes24 is a South Korean online retailer that primarily sells books, e‑books, and related cultural products. The platform also offers ticket sales for concerts, musicals, theater performances and other live events. In addition to retail, Yes24 hosts community forums where users can discuss literature, music and entertainment topics. The company serves customers mainly within South Korea, providing digital and physical goods through its website and mobile application.

Yes24 operates as one of the country’s prominent e‑commerce channels for cultural goods, connecting publishers, distributors and consumers in a single marketplace. Its services include digital downloads of e‑books, streaming of audiobooks and the sale of physical books with nationwide delivery. The ticketing function covers a wide range of events, from K‑pop concerts to classical music recitals, allowing users to purchase seats and receive mobile tickets. The platform’s integrated approach aims to provide a seamless experience for users seeking both content and live‑event access.

The firm has distinguished itself by focusing on the cultural and entertainment sector, maintaining close ties with publishing houses and event organizers to offer exclusive releases and pre‑sale tickets. After experiencing ransomware attacks in June and August 2025 that disrupted its website and mobile app, Yes24’s leadership publicly apologized and committed to overhauling its security posture, increasing investment and engaging external experts to strengthen defenses. These incidents highlighted the importance of robust cyber‑resilience for an online service that handles personal data, payment information and digital content. The company’s response has been closely monitored by South Korea’s privacy regulator, which opened an investigation into possible data exposure following the June attack.
