FATF supports Chainalysis’s findings

The Financial Action Task Force (FATF) reported in June that the use of stablecoin by criminals has increased significantly since last year. The FATF also claimed that the majority of illicit activities on blockchains involve stablecoins.  

The United Nations Office on Drugs and Crime (UNODC) also published a report in January claiming Tether (USDT) was the most popular currency for criminal gangs in Southeast Asia. The main reason stablecoins were used for laundering proceeds from criminal activities is their versatility. The UNODC noted the difficulty in smuggling fiat currencies overseas; converting them in Korea is even more challenging. 

The Chainalysis report also found that converting criminal proceeds into stablecoins allows for easy cross-border remittance. Money launderers can bypass exchanges by using overseas crypto exchanges that don’t require KYC (know your customer) verification. They can also use OTC (over-the-counter) transactions.

The report noted that while stablecoins are fundamentally traceable, their decentralized nature allows them to avoid government control.  It further noted that although the transactions may leave a trail, crypto wallets make tracking difficult because they use randomized alphanumeric characters. Tumbled or mixed stablecoins become even more challenging to track.  

Korea’s stablecoin-related fraud surges

The report also found that Korean criminals are increasingly turning to stablecoins for the so-called “Oda Jangip fraud”. The scam begins with false advertising on online shopping stores or second-hand marketplaces, and then money is scammed from unsuspecting buyers.

Stablecoins are used to launder proceeds from small-scale frauds (hundreds of thousands of dollars) and large-scale scams (hundreds of millions of dollars and more).

However, the report suggests that criminals involved in stablecoin-related crimes often receive lenient sentences. Chainalysis gave an example of one criminal who laundered over $188 million while working for a voice phishing ring in January. The criminal, whom the analytics firm chose to call Person A, bought ethereum and transferred it to an overseas crypto exchange. 

The ETH was then swapped for USDT and transferred to a crypto wallet controlled by the ring. The money laundering process began with domestic bank accounts, ETH, overseas crypto exchanges, stablecoins, and then a crypto wallet. However, the criminal received only one year and six months in prison, suspended for three years in August. 

Another criminal was reportedly sentenced to eight months in prison and two years’ probation for deceiving a victim who bought perfume through a second-hand marketplace. The criminal received the customer’s 220,000 won deposit through a fake bank account, and then exchanged it for USDT to cash out.  

The report noted that financial fraud organizations that use stablecoins primarily use tactics such as voice phishing, stock/coin “leading room” scams, and second-hand market fraud. They then seek ways to launder the proceeds cleanly and withdraw them as cash.
