Hacking Incidents Hit Bithumb, Mirae Asset Global Investments, and Daishin Securities as Breaches Spread Across Financial Sector

Hacking breaches have been confirmed at cryptocurrency exchange Bithumb, Mirae Asset Global Investments, and Daishin Securities, prompting financial authorities to assess the situation.

According to financial authorities and relevant sectors today (October 28), the Financial Supervisory Service (FSS) has additionally identified hacking breaches at Bithumb in the cryptocurrency sector, and Mirae Asset Global Investments and Daishin Securities in the financial investment sector.

Among them, Daishin Securities distributed a press release this morning stating that the personal and credit information of 38,490 customers was leaked.

Bithumb discovered yesterday that personal information had been leaked due to unauthorized access by an external unauthorized party into its internal mobile groupware system.

The company is currently analyzing the exact scope of the leak, including the possibility that member information was included.

Mirae Asset Global Investments stated that it recently detected abnormal access from an external internet protocol (IP) address in some of its web systems, blocked the access route, and activated an emergency response system.

It is currently investigating the cause of the incident and the scope of its impact. So far, the leaked information is understood to be limited to data used in some administrative systems, with no leaks of uniquely identifying information, sensitive information, or personal credit information.

The company explained that because the systems are not targeted at retail customers, investor information is not involved.

The Financial Supervisory Service is further assessing the status of the security breaches at these financial institutions, including dispatching an on-site inspection team to Daishin Securities.

In his opening remarks at a regular meeting with the board chairpersons of eight banking holding companies this morning, FSS Governor Lee Chan-jin stated, "I understand that general hacking incidents occurred across major financial investment companies yesterday," repeatedly urging the financial sector to tighten information technology (IT) security.


He noted, "As artificial intelligence (AI) is utilized as a hacking tool, security vulnerabilities are easily detected and simultaneous attacks are becoming routine," adding, "Recognizing that IT security is a core task for protecting customer assets and information and maintaining financial trust, I ask that boards of directors take the lead in enhancing IT security capabilities."

Following Mirae Asset Life Insurance on the 26th, additional breach incidents at Bithumb, Mirae Asset Global Investments, and Daishin Securities today mean that, with the exception of credit card companies, nearly all major financial sectors have been exposed to recent hacking attacks with confirmed damages.
