On September 30, 2025, Foremost Asset Management appeared on the leak site of the qilin ransomware group after the attackers exfiltrated internal company files during a ransomware incident. The South Korean investment firm, founded in 2021 in Seoul, had client and operational records taken; the precise number of individuals whose data may have been exposed remains unknown.

What Public Reporting Shows
Public reporting indicates that qilin listed Foremost Asset Management on its data leak portal on September 30, 2025. The attackers claim to have stolen internal files in a ransomware operation. Available details describe the company as a relatively new investment manager established in 2021 by businessman Kim Yong-chol. No confirmed total of affected records has been released, and the exact types of data inside the exfiltrated files have not been independently verified beyond the broad description of internal documents.
Why This Matters for You and Your Family
When an investment or asset management firm loses control of internal files, the information often includes names, addresses, contact details, account numbers, and sometimes financial history. If your family has ever worked with a firm like Foremost, used similar services, or shared personal data with financial advisors, your information could be among the records now in criminal hands. That data does not stay isolated. It travels quickly through underground markets where other criminals buy it to attempt identity theft, loan fraud, or targeted scams against you or your relatives.
Children’s records are not immune. Many families list dependents on financial forms or share family email addresses that also protect gaming accounts. A single leak can therefore place both adult finances and a child’s online identity at risk.
