The government of South Korea has launched an inquiry involving several agencies into the repeated failures of law enforcement and tax authorities to protect Bitcoin. Deputy Prime Minister and Minister of Economy and Finance, Koo Yun-cheol launched the investigation.
This investigation follows several high-profile events, including the recent release of a seed word by the National Tax Service that led to the theft of almost $4.8 million in confiscated digital assets. This is the latest in a long line of problems that show South Korean agencies aren’t very good at handling seized crypto.
In February 2026, during an internal audit, the National Tax Service mistakenly disclosed the mnemonic seed phrase for a wallet containing stolen cryptocurrencies. Hackers quickly emptied the wallet, costing an estimated 6.5 billion won ($4.8 million), mostly in Bitcoin and Ethereum.
The agency apologised publicly, saying the mistake was due to poor encryption and access controls. This episode is similar to one that happened in January, when prosecutors said $1.4 million in seized Bitcoin had mysteriously disappeared from internal custody, prompting initial internal reviews.
These mistakes are not one-time events. Since 2025, South Korean officials have been criticized for making the same mistakes over and over again. For example, a police agency hack that put seized assets at risk and mishandled private keys in another case.
PeckShield, a blockchain security company, is one of the critics who says that outmoded custody techniques, a lack of multi-signature wallets, and not enough cold storage are to blame. “Government agencies don’t have as high custody standards as private exchanges,” said a PeckShield analyst.
Minister Choi then directed the Financial Services Commission (FSC), Financial Supervisory Service (FSS), police, prosecution, and tax office to work together on a task force. The inquiry, expected to conclude by the middle of 2026, will examine all of the agency’s cryptocurrency holdings, which are estimated to be worth more than $100 million.
It will also suggest changes such as requiring hardware security modules and third-party audits. Prime Minister Koo Yun-cheol stressed the need for quick action, saying, “We can’t afford to lose more money from seized illegal gains.”
This shows how important self-custody and strong security are for both new and experienced investors. South Korea is a major center for cryptocurrencies, but it imposes rigorous restrictions on Virtual Asset Service Providers (VASPs). Now, the government is under pressure to make sure that its operations are in line with industry standards before the entire crypto legislation goes into effect in 2027.
The Digital Asset Exchange Association and other industry associations are happy with the investigation because they hope it will stop future problems and boost people’s faith in blockchain technology. The changes are a big deal for institutional crypto handling in Asia’s biggest economy, and they could change how things are done in the area.
