(LEAD) KB Kookmin Bank suffers info leak raising concerns over data breach at other lenders

KB Kookmin Bank, a prominent commercial bank, experienced a data breach that has raised concerns about potential breaches at other lenders, according to industry sources. The incident, which occurred following a similar occurrence by rival Shinhan Bank, has led to worries over widespread data leaks within the banking sector. Over 100 KB Kookmin Bank customers had their personal information stolen in the hacking incident, including names, phone numbers, and encrypted identification, according to the bank.

The lender assured that any potential damage resulting from the breach would be fully compensated. On the same day as the KB Kookmin Bank leak, Shinhan Bank disclosed that personal data of approximately 25,000 customers, such as their annual income, names, and phone numbers, had been compromised. Analysts believe that the hackers, believed to be based overseas, used advanced artificial intelligence (AI) tools to extract the information.

The attackers likely targeted vulnerable online platforms using AI-powered attacks, underscoring the necessity for financial institutions to remain vigilant and block abnormal access attempts. The entire financial industry is feared to be susceptible to AI agent-assisted attacks, highlighting the urgent need for financial institutions to conduct thorough security inspections to address potential vulnerabilities.
