Ask what Korea is talking about.

Mirae Asset Securities suffered cyberattacks on Nov. 4-5 that exposed account numbers of about 3,800 customers and personal information of 35,255 employees, including retirees and contractors, totaling roughly 39,000 people, Yonhap reports. The attacks hit the mobile web phone authentication login service and the 'mi-global' groupware system, according to the Korea Times and Kyunghyang Shinmun. The breach follows a broader wave of financial-sector leaks: the FSC reported over 470,000 personal data records leaked from 37 firms in the past month, with funds stolen estimated at 1 billion won ($745,000). Korean media coverage focuses on the scale and timing, noting the incident adds to a series of hacking cases in the financial industry, while a separate court ruling rejected Coupang's injunction against a 423 billion won fine over its own massive data leak.
