Prosecutors in South Korea are delving into a significant loss of Bitcoin, originally confiscated as criminal assets, following an internal audit that revealed the funds may have gone missing while in state custody. Authorities suspect that a phishing attack is at the root of the incident, prompting critical questions about the protocols surrounding the storage and security of seized digital assets.
Recent reporting from Yonhap News indicates that the Gwangju District Prosecutors’ Office has determined that a large quantity of Bitcoin from a previous criminal case is no longer logged in their records. Investigators believe this loss occurred in the middle of last year while the cryptocurrency was under their management. Although officials have not disclosed the specific amount or current value of the missing Bitcoin, they maintain that the ongoing investigation will provide more clarity.
An official from the prosecutor’s office stated efforts are underway to trace the seized assets. Local news reports suggest that the Bitcoin disappearance is connected to illegal gambling activities, as the currency was seized as unlawfully obtained property. Estimates circulating in the media suggest that the value of the lost Bitcoin could be in the tens of billions of won, equating to several million dollars, but these figures have yet to be confirmed by the prosecutors.
Initial findings point to a troubling storage method—the Bitcoin was kept on a portable USB rather than a more secure custody solution. Additionally, the password for the wallet was reportedly revealed to a third party during a routine examination of confiscated items, which allegedly facilitated unauthorized access and unauthorized transfers of funds.
This incident reflects a growing trend of cryptocurrency being compromised even in the hands of law enforcement, with phishing—deceptive tactics that exploit human error rather than technical vulnerabilities—emerging as a primary risk. Such attacks thrive in environments where internal controls are weak and trust is misplaced.
The Gwangju District Prosecutors’ Office has experience in handling significant cryptocurrency cases. For instance, in March 2024, they aimed to recover approximately 170 billion won, or around $127 million, in Bitcoin tied to another illegal gambling operation. Over recent years, the seizure of digital assets in South Korea has become increasingly formalized in light of several landmark Supreme Court rulings that affirmed the classification of cryptocurrencies as property under the Criminal Procedure Act.
In 2018, the Supreme Court ruled that cryptocurrencies possess intangible assets and economic value, allowing for their seizure if linked to criminal activities. Subsequent rulings have broadened the scope of seizure authority, with a December case confirming that Bitcoin held on local exchanges, such as Upbit and Bithumb, can also be confiscated.
This latest incident coincides with heightened regulatory scrutiny over the crypto sector in South Korea. Earlier this month, financial regulators expressed intentions to implement a payment freeze system, enabling investigators to temporarily suspend crypto-related accounts before any illicit funds can be transferred or moved offshore.
