Following cryptocurrency exchange Bithumb and Mirae Asset Global Investments, a hacking breach has also been confirmed at Daishin Securities.

Daishin Securities announced this morning (October 28) that personal credit information of 38,490 customers was leaked.

The Financial Supervisory Service is assessing the scale of the damage and the circumstances of the incident, including dispatching an on-site inspection team to Daishin Securities.

Regarding this, Daishin Securities explained that no signs of secondary damage resulting from the data leak or evidence of hackers illegally accessing core operational systems have been found so far.

In addition, the company plans to individually notify customers whose information was leaked, check for any damages, and take necessary measures.

Cryptocurrency exchange Bithumb also confirmed yesterday (October 27) that personal information had been leaked.

It was found that an unauthorized external party abnormally accessed the internal mobile groupware system, leading to the leak of personal information. The exact scope of the leak, including whether member information was included, is currently being investigated.

Previously, on the 26th, a security breach also occurred at Mirae Asset Life Insurance.

As hacking damages continue to hit securities firms, asset managers, and the cryptocurrency industry alike, Financial Supervisory Commission Chairman Lee Chan-jin once again called for strengthened IT security in the financial sector.

During a meeting with the chairpersons of bank holding company boards of directors this morning (October 28), Financial Supervisory Service Governor Lee Chan-jin emphasized that IT security is a core task for protecting finance and trust, stating, "As artificial intelligence is utilized as a hacking tool, vulnerability detection will become easier, and simultaneous attacks will become routine."
