"Breaching Until It Finds a Way"... Banks Go on Emergency Alert One After Another

[Anchor]

Following Shinhan Bank yesterday (October 1), customer personal information has now been leaked from Kookmin, Hana, and Busan banks as well. Hackers attempted similar attacks on banks other than these four. While the exact details have not yet been uncovered, traces of artificial intelligence utilization have been found.

Here is reporter Kim Hye-min with the details.

KB Kookmin Bank announced that the personal information of 119 customers was leaked due to an external intrusion.

The leaked data includes names, phone numbers, addresses, and encrypted resident registration numbers.

It was determined that a mobile work support system for employees was used as the hacking vector.

The bank explained that the incident is unrelated to general customer financial transactions, such as internet banking and mobile banking.

At Hana Bank, the information of 89 customers was leaked, including resident registration numbers, names, addresses, email addresses, phone numbers, mobile numbers, and workplace names.

Hana Bank stated that there was abnormal access to its sales support system.

At BNK Busan Bank, it was found that the personal information of 11 outsourced development employees was leaked early this morning through a mobile sales support system for staff.

Previously yesterday at Shinhan Bank, a webpage used by loan solicitors was initially hacked, leading to a leak of information for 25,000 customers.

In all four cases, personal information was leaked as the banks' internal business systems were breached.

Although it has not been confirmed whether the attacks were carried out by the same group, signs of AI utilization have emerged in terms of the timing and methods of the attacks.

Woori Bank and NongHyup also came under attack using the same method, but no information leaks were reported.

Financial authorities held an emergency response meeting, ordering an overall inspection of systems exposed to the outside and launching an investigation into the circumstances.
