SEOUL, Oct. 4 (Yonhap) -- President Lee Jae Myung on Sunday called for a thorough investigation into a series of hacking attacks that caused personal information leaks at major banks and other financial institutions.

Several financial firms suffered back-to-back leaks of customer information in recent hacking attacks, including Hana Bank, KB Kookmin Bank and Shinhan Bank.

"President Lee was briefed on the recent data breaches at financial and public institutions and the measures taken in response," presidential spokesperson Kang Yu-jung said in a press release.

"He instructed authorities to take the matter seriously, conduct a thorough investigation and spare no effort in coming up with measures to address the issue," she added.

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 artificial intelligence (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.

Financial Services Commission Chairman Lee Eog-weon and Lee Chan-jin, governor of the Financial Supervisory Service, held an emergency meeting to discuss the issue with the heads of the affected firms.

"We have detected multiple security breaches across various sectors in a short span of time, not only at major commercial banks but also at savings banks and specialized credit finance firms," the FSC chief said at the meeting.

He said no sensitive information that could be used for unauthorized payments appeared to have been leaked so far but urged the financial sector to maintain the "highest level of vigilance," warning that the leaked information could still be exploited for voice phishing or other scams.

He also did not rule out the possibility that AI tools were used in the hacking attacks.

首尔，10月4日（韩联社）——韩国总统李在明周日呼吁对一系列导致主要银行和其他金融机构个人信息泄露的黑客攻击事件进行彻底调查。

近期，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黑客攻击中接连遭遇客户信息泄露。

总统发言人康裕贞在一份新闻稿中表示：“李总统听取了有关近期金融和公共机构数据泄露事件以及应对措施的汇报。”

她补充说：“他指示有关部门严肃对待此事，进行彻底调查，并竭尽全力制定措施解决这个问题。”

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（AI）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。

金融服务委员会主席李玉元和金融监督院院长李灿镇召开紧急会议，与受影响公司的负责人讨论此事。

“我们在短时间内发现多个行业出现多起安全漏洞，不仅涉及大型商业银行，还涉及储蓄银行和专业信贷金融公司，”金融服务委员会主席在会议上表示。

他表示，目前似乎还没有泄露任何可用于未经授权支付的敏感信息，但他敦促金融部门保持“最高级别的警惕”，并警告说，泄露的信息仍可能被用于语音网络钓鱼或其他诈骗活动。

他也没有排除黑客攻击中使用人工智能工具的可能性。
