A worldwide law enforcement operation led by the Federal Bureau of Investigation has resulted in the arrest of 276 people linked to large-scale cryptocurrency fraud schemes and the shutdown of nine alleged scam facilities, authorities said. The networks are accused of running long-running “pig butchering” investment scams that targeted victims across several countries.
Coordinated action across three countries
Law enforcement agencies in Dubai, Thailand, and China worked with the FBI to identify and disrupt the networks behind the schemes.
- Dubai police arrested 275 suspects
- One additional suspect was detained in Thailand
- Three defendants now face wire fraud and money laundering charges in the Southern District of California
Officials described the action as one of the largest coordinated responses to date against international crypto-related financial crime.
San Diego probe at the center of the case
According to the U.S. Department of Justice, the case traces back to an investigation launched in San Diego. Agents there uncovered links connecting several entities to the fraud schemes.
Authorities say the operation involved:
- Ko Thet Company
- Sanduo Group
- Giant Company
These entities allegedly served as recruitment hubs for workers who helped operate fraudulent online investment platforms.
How the “pig butchering” scams worked
Authorities said the schemes followed a pattern designed to slowly gain victim trust before steering them into fake digital asset investments.
The structure, as described by officials:
- Fraudsters cultivate personal relationships with targets, often over weeks or months
- Once trust is built, they introduce supposed crypto trading or investment opportunities
- Victims are directed to fabricated trading platforms that appear legitimate
- Deposited funds are then moved to wallets controlled by the scammers
- The money is laundered through additional crypto accounts to obscure its origin
Losses are estimated in the millions of dollars, with victims spread across multiple countries, including the United States.
Scale of damage and growing law enforcement focus
The FBI has reported a sharp rise in digital currency fraud worldwide. In its 2025 annual report, the bureau recorded:
- $11.3 billion in losses tied specifically to digital currency fraud
- $20.9 billion in total internet crime losses
Digital asset scams accounted for more than half of all reported internet crime losses, underscoring how central such schemes have become to online fraud.
Officials say the latest operation reflects a strategic shift toward dismantling the infrastructure and service networks that support these schemes, not just arresting individual perpetrators.
Pressure on illicit crypto networks
The crackdown introduces new legal and operational risks for networks that rely on cross-border movement of digital assets. Authorities say the operation included the seizure of more than 500 domains tied to fraudulent investment platforms, directly removing a significant number of active scam sites from circulation.
Recent industry analysis estimates that illicit crypto addresses received around $154 billion in 2025, driven in part by sanctioned entities and sophisticated fraud networks. Law enforcement agencies argue that large-scale crackdowns like this one are intended to disrupt those flows and raise the cost of operating such schemes.
Blockchain tracing tools tighten the net
Officials point to improved blockchain analysis tools as a key factor enabling these actions. Because most crypto transactions leave a permanent, transparent record, investigators can:
- Trace funds across multiple wallets and services
- Reconstruct transaction paths months or years after the fact
- Connect activity on fraudulent platforms to real-world operators
This traceability has led to more asset seizures and arrests long after the original crimes took place, narrowing the space in which criminal organizations can operate.
Outlook: more enforcement actions expected
Authorities signal that similar actions are likely to continue. The Scam Center Strike Force, launched in November 2025 to target large-scale digital asset fraud, is expected to remain active and expand its work with overseas partners.
For market participants, this campaign may mean:
- Periodic disruptions as fraudulent platforms and domains are taken offline
- Changes in liquidity patterns where illicit activity had been concentrated
- Ongoing shifts in perceptions of risk, security, and regulatory scrutiny in the digital asset space
Officials say the long-term goal is to steadily dismantle the criminal ecosystems that have exploited digital currencies, while reinforcing that cross-border cooperation on enforcement is becoming the norm rather than the exception.
