KB Kookmin Bank Data Breach Follows Shinhan Leak, Raising AI Attack Concerns

KB Kookmin Bank has suffered a customer data breach affecting more than 100 people, a day after Shinhan Bank disclosed a leak of about 25,000 customer records. Industry sources say overseas hackers used advanced AI tools, raising concerns across South Korea's financial sector.

The lender said the leaked data included names, phone numbers and encrypted identification. KB Kookmin Bank added that any possible damage caused by the breach will be fully compensated, according to the reports.

The KB Kookmin incident followed Shinhan Bank's disclosure on Thursday that personal information of about 25,000 customers, including annual income, names and phone numbers, had been leaked. The two cases have drawn attention to the exposure of customer records at major commercial banks.

Sources said the hackers, currently suspected to be based overseas, used advanced artificial intelligence tools in the attacks to extract information. Shinhan Bank was likely caught in random AI-powered attacks on vulnerable online platforms, insiders said. They said the case underscored the need for other financial institutions to remain vigilant and block abnormal access attempts.

The financial industry is feared to be vulnerable to AI agent-assisted attacks, raising the need for financial institutions to promptly conduct their own security inspections to address potential vulnerabilities, according to insiders.
