South Korean financial authorities are considering introducing specific regulatory measures for cryptocurrency mixers to counter the misuse of these protocols for money laundering by criminal organizations, local media reported on January 15.
The move is driven by growing concerns that mixers, originally designed for privacy protection, are increasingly being exploited for illicit financial activities.
The South Korean Financial Services Commission’s Financial Intelligence Unit (FIU) is at the forefront of research into potential regulatory frameworks.
Mixers under fire
Cryptocurrency mixers, or tumblers, fragment and commingle digital assets, redistributing them across numerous wallet addresses, obscuring the trail of transactions and user identities.
Although these services were initially intended to protect the privacy of users with significant amounts of money, they have become a tool for criminals, including hackers, to launder money.
According to an FIU official, the lack of specific sanctions against mixers in South Korea has led to a significant risk of them being used for money laundering. The proposed regulations could restrict virtual asset service providers from engaging in mixer-based transactions.
Professor Hwang Seok-jin from Dongguk University’s Graduate School of Information Security emphasized the importance of new regulations to prevent the disbursement of stolen assets through exchanges and maintain market integrity.
Domestically, the urgency of these measures is determined by the recent hacking of the Orbit Bridge. Hackers took advantage of the protocol to steal approximately $81 million in various digital assets, believed to have been laundered through mixers.
International cooperation
This move echoes international trends and regulatory actions from other authorities, such as the U.S. Treasury Department’s Financial Crimes Enforcement Network (FinCEN), which recently issued anti-money laundering (AML) rules targeting mixers.
After this, the regulator sanctioned the crypto mixer Sinbad, which is extensively used by the North Korean hacking group ‘Lazarus’, for laundering stolen money.
There is a growing global consensus on the issue of mixers that require regulatory intervention, especially to stop their misuse by illegal actors. However, formulating concrete regulatory frameworks may take some time due to the novelty of the discussion and the need for international coordination, given the cross-border nature of the use of mixers.
The FIU said it plans to monitor the situation in other countries and will work intensively with international regulators to tackle mixer abuse.
