Ask what Korea is talking about.

Mirae Asset Securities confirmed on Saturday that hackers breached its systems, leaking the personal information of some 39,000 customers and employees, the country's leading brokerage said. Yonhap reports the breach compromised personal data of thousands, while KBS World notes it is the latest in a growing wave of cyberattacks targeting South Korea's financial sector. The Korea Times and Yonhap both cite the figure of 39,000 affected individuals, though one Korean-language report from 한국경제 breaks it down as 3,800 customers and 35,000 employees.
