Second ransomware attack in two months disrupts South Korean ticketing giant

Yes24, South Korea’s largest ticketing and online book retailer, was hit by a ransomware attack that took its website and mobile app offline for several hours (restored within seven hours), disrupting ticket sales and e-book access; this is the company’s second ransomware incident in under two months after a June attack that forced a five-day outage. The report notes no named attacker or confirmed ransom demand, prior criticisms about backup and security shortcomings, regulatory fines and earlier data-security incidents, and heightened concern because ticketing platforms hold large volumes of personal and high-value transaction data.
