Criminal networks operating across Southeast Asia and the broader Asia Pacific region stole between $88.3 billion and $114.1 billion from victims in 2025, with a significant portion of those proceeds moving through crypto channels, according to data released by the United Nations Office on Drugs and Crime (UNODC) this week.
The transformation of transnational scam networks
UNODC detailed that Southeast Asia’s illicit groups, once confined to specific territories and single criminal specialties, have fused their operations into a complex, multinational network. These syndicates now pool resources and offer each other specialized illicit services through interconnected infrastructures. Their activities encompass money laundering, fraud, human trafficking, and data theft, all managed as separate but integrated divisions.
Delphine Schantz, UNODC’s regional representative for Southeast Asia and the Pacific, likened the operational model to “corporate franchising,” emphasizing how seamlessly these criminal groups have adopted business structures traditionally seen in legitimate enterprises.
Schantz pointed out that losses attributed to scam networks have now surpassed the gross domestic product (GDP) of several countries in the region, underlining the scale and organization of this criminal industry.
UNODC estimates for 2025 place illicit proceeds at least three times higher than the $18 billion to $37 billion range recorded in 2023. The agency attributed this dramatic surge to rapid expansion and growing sophistication among organized crime syndicates. Recent years have been especially impactful for China, South Korea, and Taiwan, each reporting multi-billion-dollar losses.
| Year | Estimated Scam Proceeds |
|---|---|
| 2023 | $18 billion – $37 billion |
| 2025 | $88.3 billion – $114.1 billion |
The networks, which previously targeted primarily Chinese speakers, have expanded to reach global audiences using artificial intelligence-driven translation tools. Recruitment for these operations spans multiple languages, including English, German, and French. According to UNODC, at least 80 countries and territories have citizens identified inside scam compounds across the Mekong region.

Centers in Cambodia and Myanmar complicate enforcement
Much of the syndicates’ infrastructure is headquartered in heavily guarded compounds in Cambodia and Myanmar. These sites house both voluntary workers and victims of trafficking, many of whom are forced to carry out elaborate fake romance and crypto investment schemes. A frequently used method, known as “pig butchering,” involves cultivating relationships with victims online before defrauding them of significant sums. Funds stolen through these tactics are often laundered using blockchain-based techniques.
According to the UN report, cryptocurrencies are not merely tools for moving funds but integral to the overall criminal ecosystem. In addition to scams and frauds, proceeds from methamphetamine trafficking, child exploitation, and real estate investments are routinely cycled through crypto channels. Criminals exploit established trade routes while leveraging anonymity features of various blockchain platforms.
UNODC emphasized that conventional law enforcement strategies such as physical raids have had limited success, as criminal operations persist and adapt even after key figures are apprehended or extradited.
Recent enforcement efforts have resulted in the extradition of several alleged syndicate leaders from Cambodia to China. This follows coordinated actions by the United States and United Kingdom, which imposed sanctions on entities tied to the illegal operations.
Despite arrests and extraditions, many scam centers remain active. Schantz cautioned that distinguishing between trafficked workers and those who depart with training in illicit techniques is increasingly difficult. Returning individuals have been linked to the expansion of similar networks across Africa and the Balkans.
UNODC called for intensified and specialized police training to track, freeze, and seize proceeds of crime on blockchain platforms. INTERPOL’s operation First Light 2026, conducted from January to April, coordinated investigative efforts across 97 countries.
Enforcement results and ongoing challenges
Global police efforts recently led to the arrest of 5,811 individuals and the freezing of $293 million linked to these scam activities. In one high-profile case, a 20-year-old suspect in Thailand reportedly moved $122.5 million through a single wallet in just ten months by leveraging cross-chain token swaps to make detection more difficult.
Mini dictionary: Cross-chain token swap refers to the exchange of digital assets between two blockchain networks, enabling funds to move without passing through centralized exchanges and complicating tracing efforts by law enforcement.
Authorities continue to face significant obstacles in addressing these crimes, as syndicates persistently evolve their tactics and leverage new technologies to evade detection.
