In a sweeping international operation, U.S. authorities have frozen approximately 701 million dollars’ worth of crypto assets linked to a vast Southeast Asia-based cyber fraud ring. The investigation has also led to the takedown of hundreds of fraudulent investment websites targeting American citizens. Meanwhile, Coinbase has announced it has directly frozen 3 million dollars in illicit funds associated with the scams.
U.S. agencies and crypto exchanges joined forces
The operation was coordinated by the Scam Center Strike Force, an initiative established under the U.S. Department of Justice to combat online fraud networks. Major digital asset exchanges provided crucial technical assistance throughout the process. According to disclosed details, Coinbase detected and isolated wallets linked to money laundering of victims’ stolen funds.
Mini glossary: The Scam Center Strike Force is the Department of Justice’s operation structure designed to accelerate interagency coordination against fraud networks. On-chain monitoring refers to real-time tracking of blockchain transactions to identify suspicious addresses.
Authorities seized 503 fraudulent investment websites that had been designed to mimic legitimate financial institutions. Now, when users attempt to visit these addresses, they are met with official notices of seizure instead of fake account dashboards. In addition, a Telegram recruitment channel with over 6,000 followers was taken offline as part of the crackdown.
Officials underscored that the freezing of nearly 701 million dollars in crypto assets, the seizure of 503 fake investment domain names, and the success of the operation were only possible through close technical cooperation between government agencies and major digital asset platforms.
Targeting infrastructure and social media accounts
Tech giants such as Meta, Microsoft, and Starlink also contributed to the operation. These companies supported efforts to shut down servers and hosting infrastructure used by the fraud networks, resulting in disruptions that affected over 1.4 million social media and email accounts.
The Royal Thai Police Cyber Fraud Center conducted several arrests in connection with the investigation. Reports noted that some suspects were apprehended at border crossings for immigration violations. The U.S. Department of State has also offered a 10 million dollar reward for actionable intelligence that leads to the dismantling of Tai Chang scam operations.
Singapore operation averts $2.86 million in losses
During the same period, Singapore Police launched a parallel month-long investigation. Authorities there reported successfully preventing a potential loss of $2.86 million. The Singapore Anti-Scam Centre established direct communication channels with Coinbase and Gemini, while blockchain analytics firms Chainalysis and TRM Labs assisted in targeting risky addresses through real-time monitoring.
This coordinated response enabled direct outreach to over 90 victims, halting further transfers of funds. Furthermore, Coinbase compliance teams adjusted their automated transaction monitoring algorithms to better detect organized groups posing as customer service staff. Blockchain data indicated that these fraudulent networks could potentially expand into other layer-1 networks.
