BNK Busan Bank, 11 cases of outsourced employee personal information leaked through hacking

“No customer information leaks… Monitoring is being strengthened to prepare for additional hacking attacks.”

(Busan = Yonhap News) Reporter Soo-hee Oh = While customer information was leaked due to hacking at Shinhan Bank, KB Kookmin Bank, and Hana Bank, 11 cases of personal information of outsourced employees were also leaked at BNK Busan Bank.

According to BNK Busan Bank on the 2nd, an external web server attack attempt was made using an AI agent around 9 p.m. on the 1st.

Busan Bank said that it blocked the major attack, but during the follow-up inspection process, it was confirmed that the personal information of 11 outsourced development employees was exposed through some web pages that did not have sufficient session verification, so they immediately blocked the page.

The exposed outsourced development employee information is name, phone number, date of birth, and email address.

The webpage where the information was exposed is blocked and external access is restricted.

Busan Bank explained that this incident is believed to have occurred due to a hacking attack targeting the mobile sales support system for internal employees.

Busan Bank reported that personal information of some outsourced employees was leaked to the web page due to a hacking attack, but customer information was not leaked.

An official from Busan Bank said, "The blocking of the web page in question has ended, and we have reported the relevant information to the financial authorities. We are continuously strengthening monitoring, including conducting a thorough investigation of all external public web pages in preparation for additional similar hacking attacks using high-performance AI."
