Mirae Asset’s AI reshuffle comes amid group cyberattacks

Mirae Asset Financial Group said 20 percent of the executives promoted in Thursday's personnel changes specialize in AI transformation, digital technology or information security. The company also elevated its information security division to better protect customer assets and personal data against increasing cyberattack threats.

The changes, announced Sunday, support the group’s “Mirae Asset 3.0” strategy. Mirae Asset says the plan applies AI across its businesses and develops “asset and wealth management services centered on autonomous AI agents.”

The timing gives that strategy a concrete test. Mirae Asset said four group affiliates have reported cyberattacks, and Mirae Asset Securities disclosed unauthorized system access on Saturday. The leadership plan therefore connects AI investment with the group’s current security exposure.

What changed in the executive leadership?

Noh Yong-woo, a vice president, has been nominated as CEO of Digital X. His appointment will be finalized after the Financial Intelligence Unit accepts the required change notification and a shareholders’ meeting.

Digital X was formerly known as Korbit, a cryptocurrency exchange. The name changed after Mirae Asset Consulting, a nonfinancial affiliate of the group, acquired a 97.15 percent stake in July. The transaction gives the group a direct route into digital assets, and Noh’s nomination places him at the head of the renamed unit as CEO.

Mirae Asset expects Noh to draw on his experience in management innovation, risk management and digital asset regulatory reform. The stated aim is to strengthen ties between the group’s traditional finance operations and its digital asset business. His experience maps to a unit connecting group finance, risk controls and a newly acquired cryptocurrency business.

Woo Shin-je, a managing director at Mirae Asset Global Investments, has been appointed chief executive of Mirae Asset Energy Infra Asset Management. His mandate includes “increased investment in power infrastructure for AI data centers and energy storage systems.” The appointment gives the AI strategy an executive responsible for the physical infrastructure named in the plan.

The company said the changes placed greater emphasis on younger and female leadership. It also detailed the promoted group across its domestic and overseas operations:

• 64% were executives in their 40s.
• 17% were women.
• 30% came from frontline wealth management and pension sales operations.

Mirae Asset says the mix reflects a stronger focus on customer services alongside technology investments. Placing three in ten promoted executives in sales-facing roles keeps service managers inside the leadership cohort. That is the company’s stated balance between new technology and service delivery.

The leadership changes put AI, cybersecurity, digital assets and energy infrastructure under explicit executive oversight.

What did the cyberattack expose?

Mirae Asset Securities’ Saturday disclosure said unauthorized access to its systems exposed account numbers belonging to around 3,800 customers. The brokerage said customers’ names and other sensitive information were not compromised.

The same incident exposed personal information belonging to 35,255 current and former employees, including contract-based workers. The company said resident registration numbers, passport numbers and driver’s license numbers were not among the leaked data.

Mirae Asset Securities became the fourth group affiliate to report a cyberattack. It followed reports from Mirae Asset Life Insurance, Mirae Asset Global Investments and Energy Infra Asset Management, according to Mirae Asset.

The company framed the reshuffle against growing cybersecurity concerns across the financial industry. The sequence gives the information-security promotion a practical context. Mirae Asset said it elevated the division against “increasing cyberattack threats,” while the brokerage’s disclosure identifies customer and employee data exposed at the securities unit.

Around 3,800 customers had account numbers exposed. The employee side was larger, covering personal information for 35,255 current and former employees, including contract-based workers. The company’s description narrows the leak but does not remove the scale of either category.

Mirae Asset’s response combines specialist promotions with an elevated security organization. The announcement does not claim the reshuffle fixes the breach, but it places cybersecurity management within the group’s senior structure.

The breach remains a data-protection issue even though the company says the named identity numbers stayed out of the leak.

How does AI reach the group’s core business?

Mirae Asset’s announcements connect AI to three operating areas: client services, digital assets and physical infrastructure. The “Mirae Asset 3.0” plan calls for AI across the group’s businesses, while the executive changes give specific managers responsibility for parts of that plan.

At the client end, the company wants wealth and asset management built around autonomous AI agents. It also promoted executives from frontline wealth management and pension sales, placing service managers in the same leadership cohort. The pairing puts technical change and customer delivery inside one management group.

In digital assets, Noh’s pending appointment follows a structural change. Mirae Asset Consulting bought 97.15 percent of Korbit in July, the cryptocurrency exchange later renamed Digital X. Noh’s expected focus on regulatory reform and risk management places digital-asset oversight alongside the group’s broader financial risk work.

In infrastructure, Woo’s appointment turns AI demand into an explicit investment priority for the group. He will oversee more investment in power infrastructure for AI data centers and energy storage systems. The announcement does not provide a spending amount, project list or schedule, so the mandate signals direction without setting a measurable target.

Cybersecurity forms the third management thread. The elevated division is meant to protect assets and data, and 20 percent of promoted executives have specialties in AI transformation, digital technology or information security. That gives the group a larger pool of promoted leaders with relevant technical backgrounds.

Taken together, the appointments build management around four capabilities: AI transformation, security, digital assets and energy infrastructure. Noh is nominated to oversee the cryptocurrency-linked unit, Woo oversees energy assets tied to AI demand, and the elevated security division takes on a larger role. The plan is still organizational: the announcement names no autonomous-agent product, security target or financing figure.

The strategy remains concrete where authority and investment are named, and incomplete where the announcement offers no targets or timetable.

What should readers watch next?

Noh’s appointment has two formal gates: Financial Intelligence Unit acceptance of the change notification and a shareholders’ meeting. Until both occur, he remains a nominee for Digital X CEO. Woo’s appointment is already final, and his infrastructure mandate is attached to the role.

The more immediate test is whether the elevated information-security operation can reduce exposure after four affiliates reported attacks. The group has paired specialist promotions with separate business-unit leadership and infrastructure investment. Mirae Asset has not published targets for incident prevention or security performance.

For now, the measurable steps are regulatory approval of Noh’s appointment, increased investment in AI data-center power and storage, and stronger security management. Whether those measures change Mirae Asset’s exposure will depend on decisions and results that the group has not yet set out.
