Ask what Korea is talking about.

Mirae Asset Securities, South Korea's leading brokerage, confirmed on Saturday that hackers breached its systems, leaking personal information of some 39,000 customers and employees, according to Yonhap and the Korea Times. The Korea Economic Daily reports that 3,800 customers' account numbers and 35,000 pieces of current and former employees' personal data were exposed, with the hack detected on November 4. This is part of a wider wave: the Financial Services Commission said over 470,000 personal data records were leaked from 37 financial firms in the past month, with funds stolen estimated at 1 billion won ($745,000). Korean customers are furious, with the Dong-A Ilbo quoting a sentiment that "my personal information is public property?" as criticism grows over the financial sector's security systems amid the string of hacks.
