KB Kookmin Bank hit by data breach after Shinhan Bank leak raises sector alarm

Industry insiders revealed that hackers accessed and extracted personal data belonging to over 100 customers of KB Kookmin Bank, employing sophisticated artificial intelligence techniques. This breach follows a disclosure by Shinhan Bank that personal details of around 25,000 customers, including names, phone numbers and annual incomes, were compromised. Authorities believe the perpetrators are based overseas and are leveraging AI tools to automate attacks on weak digital platforms.

The successive incidents highlight a growing vulnerability across financial institutions to AI-enabled hacking. Experts are urging banks to conduct immediate security audits and strengthen defenses against abnormal access attempts. The situation underscores the broader risk of AI-assisted cybercrime within the financial sector.
