Korea's 37 financial firms leak 473,000 records, 1 bln won stolen

South Korean financial authorities reported that over the past month, 37 financial firms were hit by cyberattacks, leaking about 473,000 personal data records and losing about 1 billion won ($745,000) in corporate funds, Yonhap and other outlets reported on Nov. 5. The attacks began with a hack on Shinhan Bank on Sept. 30, and by Nov. 3, 40 incidents had been reported across banks, financial investment, insurance, peer-to-peer lending, and crypto asset firms. Authorities said no individual user funds have been lost so far, and the Financial Services Commission, led by Chairman Lee Eok-won, has launched comprehensive security inspections of about 580 financial institutions, electronic financial service providers, and virtual asset operators, focusing on external access points. Korean media noted that leaked information could lead to secondary damage like voice phishing, and the regulator is checking whether sensitive financial data, such as passwords, was exposed.
