In a news report exposed this week in the UTC+8 time zone, the Gwangju District Prosecutor's Office in South Korea has been accused of a significant lapse in the custody of seized Bitcoin: during a routine check of the Bitcoin password stored on a USB drive and while accessing related websites, personnel allegedly fell victim to online fraud, resulting in the assets "vanishing into thin air." Public opinion often emphasizes the scale of the loss as "worth hundreds of billions of Korean won," while simultaneously acknowledging that data sources are limited and statements are not uniform. On one hand, South Korea continues to adopt a high-pressure stance on cryptocurrency regulation, while on the other, the judicial authorities have exposed a shocking security gap in asset custody. This stark contrast has brought to light the technical shortcomings that should have remained hidden within the system.
The Scene of Missing Bitcoin on the USB Drive
● Incident Overview: According to public information, this incident occurred during a routine check by the Gwangju District Prosecutor's Office on the seized Bitcoin. Relevant personnel needed to confirm the access password stored on the USB drive. During this process, they allegedly accessed an unknown website and followed prompts, subsequently discovering that the Bitcoin, which should have been under the agency's control, was no longer accessible. Due to a lack of a more detailed timeline and operational specifics, the outside world can only reconstruct a rough outline of this security incident based on the coarse chain of "routine check—website access—suspected fraud—asset disappearance."
● Nature and Scale of the Assets: The "missing" assets are not funds owned by the prosecution but rather Bitcoin assets seized and legally confiscated during the investigation. Neither the authorities nor the media have disclosed specific amounts of Bitcoin, and the exact value in fiat currency is unknown, with only vague estimates of "approximately hundreds of billions of Korean won" repeatedly appearing in reports. Due to the lack of precise figures, it is impossible to determine whether these numbers represent a small amount of early holders' large stakes or a cumulative stock from multiple cases, making it difficult for parties involved in the case and taxpayers to assess the actual level of loss.
● Information Confusion: While intense discussions about the "missing large sum" have erupted in the public sphere, the prosecution's statement to the outside world is that it "cannot confirm this matter" (according to a single source). This statement neither directly denies the fact of asset loss nor provides any investigation progress or technical explanation, instead pushing the entire incident into a gray area of information opacity. For the involved agency, this vague response may be a way to "buy time," but for the public, it feels like another layer of fog, allowing the questions of "whether it was lost, how much was lost, and how it was lost" to continue to fester in a narrative reminiscent of Rashomon.
The Tug-of-War Over Hundreds of Billions or 70 Billion
● Discrepancy in Amount Descriptions: In reports from Chinese media, the confusion in the description of amounts is evident: some headlines directly use "hundreds of billions of Korean won" to amplify the impact of the event, while the body mentions "approximately 70 billion Korean won," with a clear discrepancy in magnitude between the two. This "one narrative in the headline, another in the body" writing style makes it difficult for readers to determine whether the information has been exaggerated in transmission or if different media outlets have selectively amplified it.
● Limitations of Single Source: Whether it is "hundreds of billions" or "70 billion Korean won," the data currently traceable almost all comes from a single channel's retelling, lacking formal statements from the Gwangju Prosecutor's Office and authoritative numerical endorsements from the South Korean judicial system or regulatory agencies. In this context, any seemingly precise amount is more of an unverified estimate or "statement" rather than factual data that can be cited as a conclusion. Prematurely treating these numbers as conclusive evidence will only lay the groundwork for subsequent backlash in public opinion.
● The Amplification of Large Numbers and Emotions: In the narrative of the cryptocurrency world, amounts in the "tens of billions" or "hundreds of billions" often carry a natural emotional amplification effect, making it easy for readers to overlook the fragility of data sources amid shock and anger. For government agencies, once labeled with "losing hundreds of billions of Korean won," even if the final facts prove the amount to be far lower, the trust crisis brought about by the initial shock is difficult to fully repair. Numbers repeated, amplified, and solidified in the information flow often carry symbolic significance far beyond the actual loss itself.
The Shortcomings of the Judicial System Under Regulatory Pressure
● Background of Policy Pressure: In recent years, South Korea has significantly tightened its regulation of cryptocurrency assets, from strengthening anti-money laundering requirements to cracking down on illegal trading, and conducting compliance reviews of exchanges and project parties, the regulatory authorities have continuously sent signals of "strong regulation." The judicial system in which the Gwangju Prosecutor's Office is situated is a key execution link in this regulatory chain aimed at combating illegal activities and seizing illicit gains, theoretically requiring greater caution and professionalism in both systems and technology.
● The Gap Between Regulatory Stance and Technical Reality: In stark contrast to the tough regulatory rhetoric, this incident has exposed the technological lag of the judicial system in the custody of digital assets—still primarily relying on traditional storage media like USB drives to act as "cold wallets," and managing them through highly manual operations such as accessing websites and entering passwords during routine checks. This mindset of treating Bitcoin as an ordinary document file reveals a significant generational gap compared to the professional custody standards for high-value digital assets within the industry.
● Concerns of Institutional Vacuum: On the surface, this is an operational-level accident, but from an institutional perspective, it reflects a broad gray area in government agencies regarding the design of cold wallet architecture, the decentralization of custody processes, and internal risk control audits. The lack of written standards on how to generate and store private keys, who has the authority to initiate transfers, how to implement multi-signature authorization and record-keeping, and how to regularly audit balances and operational records has made "using USB drives to store coins" the default practice, allowing any mistake, oversight, or even internal misconduct to potentially evolve into an unaccountable asset black hole.
When Law Enforcement Becomes a Security Weakness
● Direct Impact on Credibility: When law enforcement agencies, which should uphold the law and justly seize criminal proceeds, themselves allegedly become victims of fraud, the blow to overall public trust in the rule of law is far greater than that of a typical security incident. The public will naturally question: if even the prosecution cannot properly safeguard seized assets, how can ordinary investors trust that the regulatory system has the ability to protect their property? This is not just a technical error but a trust crisis regarding the reliability of the regulators themselves.
● Structural Capability Gap: The details of the Gwangju incident reveal that the requirements for security awareness and technical capability in cryptocurrency investigations have exceeded the scope of traditional criminal case handling. Every click made by personnel when accessing websites and entering passwords could become an attack surface, while many judicial agencies currently invest significantly less in cryptocurrency evidence collection, wallet management, and cybersecurity training. This structural capability gap makes law enforcement agencies more easily targeted as "high-value low-protection" targets when facing highly specialized online fraud or attacks.
● Common Risks from a Global Perspective: Gwangju is not an isolated case; similar incidents have occurred in other countries where courts, police stations, or related agencies have experienced theft, loss, or even internal employee embezzlement of seized cryptocurrency assets. Common issues include: storing high-value assets on single-point devices, concentrating private keys in the hands of a few, lacking independent audit mechanisms, and lacking standardized access processes. Once problems arise, it is difficult to quickly trace the technology or clearly delineate responsibility, often resulting in the issue being vaguely referred to as an "accident."
How to Safely Custody Seized Coins
● Comparison of Traditional Practices and Industry Solutions: Many public authorities still rely on the rough model of "USB drive + password," believing that offline storage is sufficiently secure. However, in the cryptocurrency industry, a more mature set of solutions has already formed, including multi-signature wallets, hardware security module (HSM) key management, and professional custody services. Compared to a single USB drive, multi-signature solutions can technically enforce that multiple parties must jointly authorize any asset transfer, while professional custodians significantly reduce the risk of single-point errors or internal malfeasance through distributed key management, insurance mechanisms, and rigorous audits.
● Custody Entities and Responsibility Allocation: Even if there is an awareness of the need for a more professional custody mechanism, a series of practical issues arise: should the custody be handled by the prosecution, the court, or an independent third party? How should power be decentralized and balanced among different institutions to avoid "one person having the final say"? Who is responsible for regularly auditing asset balances and operational records, and who initiates investigations and compensation in case of anomalies? Only when the custody entity, audit mechanism, and responsibility allocation are clearly written into rules and subject to external supervision can seized cryptocurrency assets avoid "disappearing" again in institutional gaps.
● Directions for Improvement in Technical Standards and Transparency: For South Korea and other countries' judicial agencies, the next step in improvement is not merely "replacing USB drives with more advanced wallets," but rather constructing a complete framework that encompasses technical standards, third-party cooperation, and information disclosure. For example: establishing unified technical specifications for cryptocurrency asset custody, introducing qualified third-party custodians or audit agencies, moderately disclosing custody methods and balance changes for significant seized assets, and providing verifiable technical explanations in the event of risk incidents. Only under the dual enhancement of transparency and professionalism can "safe custody" become more than just a slogan.
Looking at the Future of Cryptocurrency Regulation Through a USB Drive
The incident of the Gwangju Prosecutor's Office losing Bitcoin on a USB drive has sharply exposed the dual gap in awareness and capability of the traditional judicial system when facing cryptocurrency assets: while narratively emphasizing high-pressure regulation and cracking down on illegal trading, in practical operations, it still manages high-value digital assets with USB drives and manual operations, lacking sufficient vigilance against online deception and technical attacks. This cognitive dissonance not only places the seized assets themselves at risk but also erodes judicial credibility in a series of information Rashomon-like narratives.
Looking ahead, South Korea is likely to face dual pressure from public opinion and the industry regarding law enforcement processes, asset custody, and information disclosure: on one hand, it needs to establish a more rigorous digital asset management system and technical standards internally, involving professional expertise in cold wallet design and custody; on the other hand, it also needs to provide clearer explanations and verifiable data on significant asset incidents to repair the amplified doubts caused by information opacity. From a broader perspective, this incident will also prompt more countries to reassess the infrastructure construction of their judicial systems in the cryptocurrency era, rather than merely stopping at the level of "strengthening regulation."
For market participants, while chasing dramatic labels like "hundreds of billions of Korean won" and "shocking scandals," it is crucial to remain vigilant against the inherent risks of incomplete information and numerical exaggeration: verify whether the source of the numbers is singular, whether there is clear official confirmation, and whether the descriptions have been amplified in transmission. Only after the facts and figures have been repeatedly verified can discussions surrounding regulation and justice return to a rational track, rather than being swept up in successive sudden events.
