According to Sina Finance, the agency, which oversees security and cyberattack prevention in South Korea's financial industry, detected the breach at about 3 p.m. local time on Tuesday and immediately notified senior financial regulators. The stolen data included about 200 administrative forms, such as consent forms authorizing the use of personal information, and personal details for about 300 people, including names and dates of birth.
