Hacking attempts on BOK, state lenders top 1 million

What happened: South Korea's central bank and three state lenders recorded more than 1 million hacking attempts in the first nine months of the year, surpassing the full-year total for 2025. Key numbers: 1,024,478 attempts through September, up 9.6 percent from 934,858 last year. Attempts rose from 358,800 in 2020. Why it matters: No breaches were reported from the attempts between 2020 and September this year. The figures follow customer data leaks at Shinhan Bank, KB Kookmin Bank and Hana Bank, and regulators have ordered firms to inspect externally accessible systems and tighten controls.
