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.

KakaoBank to Conduct Routine Due Diligence on Crypto Exchange Coinone

KakaoBank to Conduct Routine Due Diligence on Crypto Exchange CoinoneKakaoBank, one of South Korea’s Internet-only banks, is set to conduct a routine due diligence examination on cryptocurrency exchange Coinone from May 8 to 9, according to crypto media Digital Asset.Photo by Markus Winkler on UnsplashThe mobile bank told Digital Asset that the forthcoming due diligence is unrelated to either the alleged illicit token listings involving former Coinone employees or the exchange’s sole relisting of the WEMIX token in February, which had been delisted from major Korean crypto exchanges due to questionable information about the token’s circulating supply.In Korea, crypto trading platforms supporting Korean won trading are legally obligated to obtain real-name bank accounts from a bank. Last August, KakaoBank signed a one-year contract with Coinone to provide such accounts to the exchange, and the bank will need to decide whether it will extend the contract before August this year.A Coinone official said that the exchange has not undergone any routine due diligence checks from KakaoBank since the contract was signed last year.The upcoming examination is expected to address concerns stemming from rumors that KakaoBank might reconsider its contract with Coinone in light of the bribery scandal that involved two former Coinone personnel and two brokers.

United Nations report cites popularity of USDT for fraud in Southeast Asia

USDT, the leading U.S. dollar stablecoin issued by Tether, has been highlighted as a major conduit for money laundering and scams in Southeast Asia, according to a United Nations report released on Monday.Photo by Mathias Reding on UnsplashIllicit stablecoin useThe report has been titled “Casinos, Money Laundering, Underground Banking, and Transnational Organized Crime in East and Southeast Asia: A Hidden and Accelerating Threat.” It points out that online gambling platforms, particularly those operating illicitly, are among the favored channels for cryptocurrency-based money launderers, with a notable emphasis on the use of Tether or USDT. In a foreword to the report, Jeremy Douglas, the UN’s Regional Representative for Southeast Asia and the Pacific, noted that technology had aided crime networks in Asia, and in particular, the Mekong Delta region. Developing upon that idea, he added:”This has necessitated a revolution in the regional underground banking architecture, resulting in the development of systems and infrastructure capable of moving and laundering massive volumes of state-backed fiat and cryptocurrencies.”The report itself asserts that illegal and under-regulated crypto exchanges have become “foundational pieces of the banking architecture used by organized crime.” The document highlights law enforcement efforts in disrupting multiple money laundering networks linked to the illicit transfer of Tether funds. Last August, Singaporean authorities dismantled a network through an operation, recovering approximately $735 million in both cash and cryptocurrency. ‘Pig butchering’The UN report further suggests that USDT has been extensively employed in various underground fraud activities, including so-called "pig butchering" romantic scams. Last November, Tether froze $225 million in stolen USDT following investigations by Tether in collaboration with crypto exchange OKX and the U.S. Department of Justice. The money had been held in self-custodied wallets associated with an international human trafficking group in Southeast Asia orchestrating a pig-butchering scam. In December, Tether CEO Paolo Ardoino informed U.S. legislators in a shared letter that the company has enlisted the U.S. Secret Service and Federal Bureau of Investigation onto its platform. Later that month, the Chinese authorities uncovered a massive underground banking operation that was designed to evade the country’s foreign exchange controls. There was more related activity in December when it emerged that USDT has been integrated into the shadow economy in Cambodia, against a backdrop of the currency being prohibited for the purpose of trade within the Southeast Asian country. TRM Labs reportIn July of last year, a report by blockchain analytics firm TRM Labs, found that pro-ISIS terrorist groups in Central and Southeast Asia and the Middle East are increasingly using cryptocurrency, with a particular preference for USDT transacted over the Tron blockchain network. The UN report cites the popularity of USDT among those engaged in cyber-fraud and online casino operations, located in Myanmar, along the border with Thailand. Throughout 2023, Tether witnessed a notable expansion in its share of the global stablecoin supply, growing from 50% to 71%. At the time of writing, USDT has a market cap of $95 billion with stablecoins having an overall market capitalization of $134 billion. The UN's findings raise concerns about the stablecoin's role in facilitating illicit activities and underscore the need for enhanced regulatory scrutiny within the rapidly evolving crypto landscape.
