SEOUL, Oct. 6 (Yonhap) -- The country's financial watchdog has pinpointed 28 internet protocol (IP) addresses in the United States, Japan and 10 other countries used for a series of recent hacking attacks against Korean financial institutions, industry sources said Tuesday.

Several financial companies, including Hana Bank, KB Kookmin Bank and Shinhan Bank, suffered back-to-back leaks of customer information in recent hacking attacks last week, raising concerns that more firms might have suffered data breaches.

According to the sources, the Financial Supervisory Service (FSS) has shortlisted IP addresses in 12 countries as of 6:00 p.m. on Monday, which are presumed to have been used for the artificial intelligence (AI) agent-backed hacking.

But it has not been able to pinpoint the locations of some of the IP addresses, they said.

Local financial firms have been in a hurry to check their own security systems to fend off any additional hacking attempts.

Over the weekend, President Lee Jae Myung called for a thorough investigation into the attacks.

On Thursday, Shinhan Bank said personal information of around 25,000 customers, including their names, phone numbers and annual income, had been leaked. Sources said the bank was attacked by hackers who utilized advanced AI tools.

Personal information of 89 customers was found to have been leaked from Hana Bank, while Woori Bank and NH Nonghyup Bank were also targeted in similar hacking attempts, though no personal information was leaked as the banks blocked unauthorized access to their systems.

首尔，10 月 6 日（韩联社）——业内人士周二表示，韩国金融监管机构已确定了 28 个互联网协议 (IP) 地址，这些地址位于美国、日本和其他 10 个国家，用于近期针对韩国金融机构的一系列黑客攻击。

包括韩亚银行、KB国民银行和新韩银行在内的多家金融公司在上周遭遇黑客攻击，客户信息接连泄露，引发人们担忧可能还有更多公司遭受数据泄露。

据消息人士透露，截至周一下午 6 点，金融监督院（FSS）已将 12 个国家的 IP 地址列入候选名单，这些地址被认为被用于人工智能（AI）代理支持的黑客攻击。

但他们表示，目前还无法确定某些 IP 地址的具体位置。

当地金融公司纷纷抓紧检查自身的安全系统，以抵御任何进一步的黑客攻击。

周末期间，李在明总统呼吁对袭击事件进行彻底调查。

周四，新韩银行表示，约2.5万名客户的个人信息遭到泄露，其中包括姓名、电话号码和年收入。消息人士称，该银行遭到黑客攻击，黑客使用了先进的人工智能工具。

韩亚银行 89 名客户的个人信息被发现泄露，而友利银行和 NH 农协银行也成为类似黑客攻击的目标，但由于银行阻止了对其系统的未经授权的访问，因此没有个人信息泄露。
