Daishin Securities confirmed that personal and credit information of 38,490 customers was leaked, after hackers made abnormal access attempts to a server linked to non-face-to-face investment account openings on the 17th, according to Yonhap and Chosun Ilbo. The brokerage blocked the attacking IPs, reported to regulators, and is investigating the breach's scope with the Financial Security Institute. The Korea Times reports the leak included names, email addresses, and mobile phone numbers, and that Daishin, along with Mirae Asset Global Investments and Bithumb, are among the latest victims of cyberattacks on Korea's financial sector.
