Ask what Korea is talking about.

Mirae Asset Securities said Saturday that cyberattacks leaked account numbers of about 3,800 customers and personal information of more than 35,000 current and former employees and contractors, Yonhap and the Korea Times report. The breach is part of a wider wave: the Financial Services Commission says over 470,000 personal data records have leaked from 37 financial firms in the past month, with funds stolen estimated at 1 billion won ($745,000). Korean outlets frame the incident as the latest in a growing series of attacks on the financial sector, with KBS World noting hackers breached Mirae Asset's systems and compromised thousands of records.
