Attempts to Access K-Bank and KakaoBank Blocked Amid Hacking Concerns

Recent attempts to access the servers of K-Bank and KakaoBank were made using IP addresses associated with recent hacking incidents targeting major financial institutions. However, these attempts were successfully blocked by security systems, preventing any personal data breaches or actual harm.

According to the financial sector on October 6, some of the IP addresses used in the hacking of commercial banks attempted to access the servers of KakaoBank and K-Bank this year, following similar attempts at Toss Bank.

Both banks reported that no actual damage occurred. K-Bank confirmed that it detected the access attempts during a recent security check and took measures to block the IP addresses. KakaoBank also detected and blocked attempts to probe for vulnerabilities through its security systems.

Earlier, on October 5, Toss Bank reported that there had been about ten access attempts from the same IP addresses between January and August of this year. Toss Bank also blocked these attempts, ensuring that no personal data was compromised.

A K-Bank representative stated, "There were simple access attempts, but there were no unusual incidents or damage. We have completed blocking the IP addresses through recent security checks." A KakaoBank representative added, "There were attempts to explore vulnerabilities from external sources, but we detected and blocked them through our security systems. We will continue to monitor and respond to new security threats."

Meanwhile, financial authorities have shared the IP addresses used in these attacks with banks, savings banks, and capital companies, instructing them to conduct their own security checks in light of recent data breach incidents.
