Crypto Money Laundering Case of 113 Million USD in South Korea: The Fight Against Hacks and Financial Risks

South Korean authorities have recently uncovered and arrested an international criminal group consisting of 3 Chinese nationals, who operated a massive crypto money laundering ring with a total value of up to $113 million. This case not only exposes vulnerabilities in the digital currency management system but also raises concerns about how criminal groups exploit loopholes to hack and illegally transfer assets.

Sophisticated Tactics: From Crypto Shopping to Fiat Conversion

According to investigations, over the past 4 years, this criminal group operated entirely in secret. They purchased cryptocurrencies from abroad and transferred them to cold wallets in South Korea. The next step was converting them into fiat currency through popular mobile payment apps like WeChat Pay and Alipay, then paying customers on demand without leaving traces. This method allows the group to avoid official banking channels and standard control measures.

Blockchain Hacking Techniques: Peeling Chains and Hwanchigi

To evade investigators, the criminal group employed advanced hacking techniques on the blockchain network. First is Peeling Chains—a technique that isolates funds and splits them into thousands of smaller transactions across multiple wallets, making tracing extremely complex and difficult. Second, they used an underground transfer method called Hwanchigi, a minimally controlled transfer channel designed to hide the origin of the money.

Additionally, a notable detail is that one member of the group used a fake identity, impersonating a cosmetic consultation manager, to lure VIP clients into illegally transferring money and avoiding fees from official banks.

South Korea Tightens Regulations: Travel Rule and Strict Penalties

Following this hack and investigation, along with other security incidents at exchanges in South Korea, the government has decided to tighten crypto regulations significantly. The new Travel Rule will be strictly enforced, requiring detailed scrutiny even for transactions below $680, a relatively low threshold compared to international standards.

More notably, crypto exchanges face the threat of penalties up to 10% of their total assets if a hack or security breach allows malicious actors to steal investor funds. This penalty level is considered extremely harsh within the industry.

Is Strict Regulation the Solution for Crypto?

The question arises: does tightening regulation truly protect investors and eliminate risks from hacking and crime, or is it an overreach that could destroy the decentralized nature of blockchain technology? Will these new regulations impact user anonymity and privacy, or are they a necessary step to clean up the market?
