Reports say President Lee Jae-myung (이재명) called for a thorough investigation into a series of personal data leaks at financial institutions. According to the reports, President Lee ordered an investigation after receiving a briefing on recent information leaks at financial and public institutions and the response measures taken. The article was posted at 3:17:21 p.m. on October 4, 2026 (Korea time).

Other reports provided mention leaks at Shinhan Bank (신한은행), KB Kookmin Bank (KB국민은행), Hana Bank (하나은행) and BNK Busan Bank (BNK부산은행). However, the institutions and information about those affected vary from one article to another, and the full scale of the damage and the investigation’s findings are not provided.

Background and context

The reports provided say that customer information has been leaked in a series of recent hacking incidents targeting financial institutions. A leak affecting about 25,000 Shinhan Bank customers was reported on Thursday, followed by reports of similar incidents at KB Kookmin Bank, Hana Bank and BNK Busan Bank on Friday. The reports add that leaks also spread to non-bank financial institutions.

The information reportedly leaked included customers’ names and phone numbers, annual income and loan limits. Some customers’ resident registration numbers were also reportedly exposed, but the materials provided do not show the full details of what information was leaked at each institution or how many people were affected.

The key point is to distinguish between reports that an investigation was ordered and confirmation of the actual scope of the damage and the investigation’s findings.

What this news means

For customers of financial institutions, the immediate concerns are what types of information were leaked and whether their own information was included. Since the reports mention not only names and phone numbers but also income, loan information and some resident registration numbers, announcements from each institution and the investigation’s findings will be needed to clarify what steps individuals should take. However, the reports provided do not confirm whether any individual customer was affected or what follow-up action they should take.

For example, a customer of one of the banks can check the financial institution’s official announcements to see whether their information was among the data affected and what information was exposed. This is a suggested way to check, based on a hypothetical situation; the materials provided do not state that any particular customer was actually affected.

Points that differ between reports

Report 2 said President Lee called for an investigation, while Report 3 said he ordered an investigation and the preparation of countermeasures. The wording differs, but both reports indicate that the president was briefed on information leaks at financial institutions and called for a thorough investigation.

Report 2 mentioned Hana Bank, KB Kookmin Bank and Shinhan Bank. Report 3 also included BNK Busan Bank, gave the reporting dates for each bank, and provided details about the scale of the Shinhan Bank incident and the types of information leaked. The materials provided do not make it possible to determine whether these differences reflect the scope of the reports or the inclusion of additional incidents.
