South Korean Tax Agency Considers External Crypto Custody After Security Breach

South Korea's National Tax Service (NTS) is reevaluating its approach to managing seized cryptocurrency assets following a significant security breach in February 2025. The incident, which resulted in the loss of approximately $4.6 million worth of cryptocurrency, highlighted the agency's internal limitations regarding digital asset protection.

The NTS currently manages cold wallets containing seized virtual assets but lacks specialized expertise in blockchain technology and digital asset protection. This realization has prompted senior officials to consider external custody solutions as part of broader security reforms. The National Assembly is simultaneously examining the agency's proposed follow-up measures, creating legislative pressure for substantive change.

The global community is watching South Korea's approach closely, as it reflects a broader international challenge facing law enforcement and tax agencies worldwide. Governments increasingly confiscate cryptocurrency during investigations but struggle with secure long-term storage, recognizing that private sector expertise is essential for proper management.
