In a landmark demonstration of legal authority over digital assets, South Korean prosecutors have successfully sold 320.88 bitcoins (BTC) recovered from a phishing scheme, netting 31.58 billion won (approximately $24.1 million) for the state treasury. The Gwangju District Prosecutors’ Office conducted the sale over an 11-day period from February 24 to March 6, 2025, executing transactions in small increments to minimize market disruption and secure optimal value. The entire sum was immediately transferred to the national treasury.
The bitcoins originated from a phishing attack discovered in August 2024. Prosecutors became aware of the theft on February 16, 2025, and through a rapid digital forensic operation and collaboration with domestic and international cryptocurrency exchanges, they fully recovered the assets by February 19. This case underscores the growing capability of global law enforcement to track, seize, and liquidate illicit cryptocurrency, providing a blueprint for international cooperation.
In a related but contrasting development, South Korea’s National Tax Service (NTS) is actively considering external professional custody for seized cryptocurrency assets following a devastating security breach on February 26, 2025. The agency inadvertently published a mnemonic code in an official press release, enabling unknown actors to drain approximately 6 billion won ($4.6 million USD) worth of cryptocurrency from government-controlled wallets. The National Police Agency’s Cyber Terror Investigation Unit has launched a tracking operation.
The incident exposed fundamental vulnerabilities in the NTS's internal digital asset management protocols, prompting a major policy review. The agency, which manages cold wallets containing seized virtual assets, now recognizes its lack of specialized expertise in blockchain technology and digital asset protection. Senior officials are reviewing external custody solutions involving third-party custodians with institutional-grade security protocols, multi-signature wallets, and comprehensive insurance. The National Assembly is examining the agency’s proposed follow-up measures, creating legislative pressure for substantive change.
These parallel events highlight South Korea’s evolving and sometimes challenging approach to state-held digital assets. The prosecutors' successful, orderly liquidation contrasts with the tax service's security failure, together illustrating the spectrum of government competency in crypto asset management. The Gwangju sale is noted as part of a global trend where governments like the United States Department of Justice and UK agencies are developing frameworks to handle seized digital currencies, though the South Korean model emphasizes rapid post-recovery liquidation to mitigate price volatility risk.
