U.S.-sanctioned Huione Group suspected of supporting crypto transactions in Korea

Policy & Regulation·October 24, 2025, 6:50 AM

A Cambodia-headquartered financial group recently cut off from the U.S. financial system is suspected of having operated in South Korea, raising fresh questions about cross-border crypto and currency flows tied to the group.

 

According to the Dong-A Ilbo, which cited data from the Korea Customs Service (KCS), Huione Group—now sanctioned by the U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN)—appears to have run a currency exchange in Seoul from 2018 to July 2024. The outlet reported that a banner on the premises displayed a logo identical to Huione’s, prompting suspicions about its ownership and control.

Ties to North Korean hackers

The exchange reported conducting roughly $20,000 in annual currency conversions during that period, excluding cryptocurrency transactions. The timeline overlaps with a period in which Huione Group reportedly received $150,000 in cryptocurrency from the North Korean hacking group Lazarus. 

 

Connections also extend to Cambodia. Panda Bank—a local lender that shares a building with Huione subsidiaries—supports USDT transactions originating from South Korea. Panda Bank director He Yanming is listed as the owner of Huione Crypto, a virtual asset service provider (VASP), suggesting potential links between operations in Seoul and Phnom Penh.

 

These developments come against the backdrop of a U.S. investigation disclosed in May, in which FinCEN said Huione’s business networks, including payments arm Huione Pay, collectively laundered at least $4 billion in illicit proceeds between August 2021 and January 2025.

 

Crypto used in $2.6B illegal conversions

Meanwhile, recent KCS data also shows a rise in illegal currency conversions involving cryptocurrency by foreign nationals. The Korea Economic Daily reported conversions totaling 432 billion won ($302 million) in 2021, climbing to 836 billion won ($584.5 million) in 2023 and 956 billion won ($668.4 million) last year. Over the past eight years, the total amount involved in such cases reached 3.7 trillion won ($2.59 billion) across 28 instances. By value, Chinese nationals accounted for 84.1% of the total, followed by Australians (11.1%), Vietnamese (3.2%), and Russians (1.6%).

 

The growing prevalence of cryptocurrency in illicit activity parallels a broader surge in crypto investment within the country. Many South Koreans have turned to digital assets, often with home ownership as a long-term goal. Trading on local exchanges, Bloomberg reported, is heavily skewed toward more volatile altcoins, which make up more than 80% of total volume. 

 

That stands in contrast to global markets, where investors largely focus on Bitcoin and Ethereum, which together make up more than half of overall trading. The momentum in local crypto investment intensified after Donald Trump’s U.S. presidential victory, with crypto trading in Korea reaching $27 billion in December 2024, about 80% of turnover on the KOSPI stock index.

 

The investigation underscores the growing challenge for regulators in tracking and containing cross-border financial networks that rely on cryptocurrency and informal money transfers. As crypto adoption deepens in South Korea and scrutiny widens abroad, authorities find themselves navigating an increasingly intricate intersection of financial opportunity, enforcement, and risk.

bitFlyer Moves to Comply With Travel Rule

bitFlyer Moves to Comply With Travel RulebitFlyer, a Tokyo-based Bitcoin exchange and marketplace, has taken steps to comply with the travel rule, an anti-money laundering measure promoted by Paris-based global financial crime watchdog, the Financial Action Task Force (FATF).The rule necessitates the exchange to pass on customer data to a recipient exchange where the crypto transaction involves a value of greater than $3,000.Photo by Ivan Babydov on PexelsImplementing TRUST technologyThe company announced on Tuesday that these measures, which went into effect in the afternoon local time, include restrictions on transfers from the exchange to platforms that do not comply with the Travel Rule Universal Solution Technology (TRUST). This technology was initiated by Coinbase, the US-based crypto exchange, to ensure that firms adhere to FATF’s requirements. The mechanism is a product of the collaboration of Coinbase alongside leading crypto exchanges such as Kraken, Gemini, BitMEX, Bittrex, Okcoin, and others.To enforce these measures, bitFlyer has established notification requirements for receiving and sending crypto to TRUST-compliant platforms in a list of 21 countries. The list includes Japan, Israel, Gibraltar, Hong Kong, the Bahamas, and Switzerland. Additionally, bitFlyer has limited transfers to compliant platforms in these countries to TRUST-compatible crypto assets such as bitcoin (BTC), ether (ETH), and several ERC-20 tokens.On the other hand, transfers to and from countries not on the list, as well as transfers to private self-custodied wallets, can be conducted using any crypto asset available on the bitFlyer platform.Compliance with Japanese legislationWhile the exchange refers to travel rule compliance relative to 21 countries, it’s unlikely to be a coincidence that the Japan-headquartered company has implemented this compliance measure a couple of days before Japan is set to introduce a FATF travel rule compliance requirement which comes into effect on June 1.These measures align with Japan’s recent commitment to implementing FATF’s travel rule, which requires the sharing of crypto transaction information between platforms. The watchdog had urged advanced economies in the G7 to take the lead in combating money laundering through digital assets.Increasing regulatory demandsIt is worth noting that bitFlyer’s US unit recently faced a fine from US financial regulator, the New York State Department of Financial Services (NYDFS), due to its failure to meet cybersecurity requirements. The incident highlighted the increasing scrutiny and regulatory demands placed on crypto exchanges to ensure the security and compliance of their operations.By aligning itself with the FATF Travel Rule and implementing these restrictions, bitFlyer aims to enhance its anti-money laundering efforts and contribute to global efforts to combat financial crimes in the crypto space, helping to steer itself clear of potential issues with global regulators.As the crypto industry continues to evolve, regulatory frameworks and standards are being established to address concerns regarding money laundering and illicit activities. Compliance with such regulations is essential for crypto exchanges to foster trust among users, attract institutional investors, and contribute to the overall maturation and legitimacy of the crypto ecosystem.

Binance Introduces Dedicated Trading Platform in Japan

Binance Introduces Dedicated Trading Platform in JapanGlobal cryptocurrency exchange Binance made an announcement on Friday regarding its plans to establish a new trading platform exclusively for residents of Japan.The move is in compliance with Japanese laws and regulations, and a demonstration of the company coming into line with Japan’s legal and regulatory framework relative to crypto assets and crypto asset trading. While specific details such as the platform’s launch date are yet to be disclosed, Binance has assured its Japanese customers that this information will be provided in the near future.Photo by Bagus Pangestu on PexelsPlatform transitionIn terms of scheduling, we do know that a new know your customer (KYC) verification process will be available after August 1, to migrate to the new local platform for existing Japanese users on the global platform. As part of the transition process, Binance will be sending out information to Japanese residents who currently utilize their global trading platform. This communication will include instructions on procedures including further information on identity verification.To facilitate a smooth transition, Binance’s global trading platform will cease providing services to Japanese residents on November 30, 2023. Additionally, there are plans to change the company name from Sakura Exchange Bitcoin to “Binance Japan Co., Ltd.”This development marks Binance’s initial foray into the Japanese market firmly under its own brand. In November 2022, the company entered the country by acquiring Sakura Exchange Bitcoin (SEBC). The forthcoming trading platform, dedicated exclusively to domestic residents, represents the first step in Binance’s strategic approach to the Japanese market.The new services on the platform are set to launch during the summer, with future expansion plans to broaden that offering further. Binance also intends to introduce initiatives in Japan that leverage its ecosystem, including the provision of free educational resources through “Binance Academy” to promote Web3 education.Service offeringThe newly created entity will offer crypto spot trading with fiat deposit and withdrawal facility to its Japanese customers. Crypto lending products will be provided through a digital asset earn program. For those who like to dollar cost average (DCA), an automated recurring purchase feature will be provided.In 2021, Binance introduced an NFT marketplace and that will be a service that it will also extend to its Japanese customers. Upon launch of the dedicated service, crypto derivative trading will not be offered although it is understood that it may be offered at a later stage. Derivatives are likely to be under much closer scrutiny by the Japanese regulator than Binance’s other products.It is worth noting that Binance had previously received a warning from the Financial Services Agency (FSA) for offering cryptocurrency trading services to Japanese residents without proper registration. With its full-fledged entry into the Japanese market, it remains to be seen what impact this move will have. Will it accelerate the regulatory landscape and the adoption of Web3 technology in Japan from a global perspective?Additionally, how smoothly will Binance be able to acquire new accounts while competing with domestic business operators? These developments warrant close attention as they unfold.

South Korean Prosecutors Fail to Recover Do Kwon’s Assets

South Korean Prosecutors Fail to Recover Do Kwon’s AssetsSouth Korean prosecutors have disclosed that they have been unable to find the millions of dollars that Do Kwon, CEO and Founder of Terraform Labs, made from the crypto business.©Pexels/GratisographyOverseas assetsThe latest development in the case suggests that Kwon may have tried to hide his assets overseas, making it more challenging for authorities to recover those funds.Prosecutors claim that Do Kwon transferred funds from his personal accounts to overseas bank accounts under his mother’s name. Additionally, he allegedly used cryptocurrency to purchase real estate and other assets in the United States, which he then registered under his mother’s name. This tactic is commonly used by those seeking to evade detection and protect their assets from seizure.Binance halt requestSouth Korean authorities are understood to have reached out to global cryptocurrency exchange, Binance, requesting it to halt any withdrawal request associated with Kwon. Binance confirmed to CoinTelegraph that it is cooperating with the request, stating: “We provided Korean law enforcement authorities with the requested assistance. Since we cannot comment on ongoing law enforcement investigations, for any further comment please reach out to the prosecutors.”Blockchain forensicsThe situation surrounding Do Kwon’s case is not uncommon in crypto. Although there are blockchain forensic analysis specialists who collaborate with government authorities in tracing digital assets, the task is not without its difficulties. By analyzing the blockchain, investigators can trace the flow of funds and identify the individuals involved in illicit activities. This technology has already been used in a number of high-profile cases, including the 2014 Mt. Gox hack and the 2020 Twitter hack.Nevertheless, the anonymous nature of blockchain transactions makes it much easier for individuals who engage in fraudulent or illegal activities. However, as cryptocurrency becomes more mainstream, governments around the world are cracking down on those who attempt to take advantage of the system.Tightening regulationIn South Korea, authorities have been working to regulate the cryptocurrency industry and protect consumers from fraud. The government has implemented a number of measures, including requiring cryptocurrency exchanges to register with the Financial Services Commission and banning anonymous transactions. Despite these efforts, however, incidents of fraud and embezzlement continue to occur.The fight against cryptocurrency-related crime is far from over. As the industry continues to grow and evolve, criminals will continue to find new ways to exploit the system. It is up to regulators and law enforcement officials to remain vigilant and adapt to these changes in order to protect consumers and ensure the integrity of the financial system.In the case of Do Kwon, the investigation is ongoing, and it remains to be seen what the final outcome will be. Prosecutors estimate total proceeds of Do Kwon’s alleged crimes to amount to 91.4 billion won ($71 million) while 414.5 billion won ($316 million) has been identified relative to Terraform Labs more broadly.
