Short version: The UK government has sanctioned the Xinbi Guarantee online marketplace, a major hub in a Chinese-language criminal ecosystem that has helped run and fund large-scale cryptocurrency scams tied to brutal scam compounds in Southeast Asia.
What is Xinbi?
Xinbi Guarantee is an online marketplace used by Chinese-language cybercriminals. It has offered services that support online scams: selling stolen data, providing money-laundering services, and supplying technical infrastructure needed to run large fraud operations. Analysts say Xinbi has processed huge sums of cryptocurrency and played a role in funding centers where victims were forced to work.
Numbers that make your eyes water
- Crypto-tracing firm Elliptic reported that Xinbi facilitated at least $8.4 billion in transactions since 2022, with most likely coming from stolen funds.
- Chainalysis estimates Xinbi handled about $19.9 billion between 2021 and 2025.
- Another analyst estimate puts Xinbi-linked flows at about $19.7 billion when including merchants and infrastructure tied to the marketplace.
What the UK did
The United Kingdom’s Foreign, Commonwealth and Development Office announced financial sanctions targeting Xinbi and several individuals allegedly connected to large scam compounds in Cambodia. The action also included the seizure of property in London, notably a penthouse valued at around 9 million.
Officials named Xinbi as a platform that has enabled, and profited from, human rights abuses in some of these scam centers.
Who else was targeted
- Individuals tied to industrial-scale scam compounds, including the so-called #8 Park site (reported to host thousands of people), were sanctioned.
- The government said the penalties are meant to make it harder for Xinbi, its merchants, and users to spend or exchange cryptocurrency that passed through the marketplace.
How Xinbi keeps surviving
Xinbi has shown a talent for recovery. After a Telegram purge removed channels tied to major marketplaces, Xinbi rebuilt its presence on messaging platforms, created new channels, and expanded its payments setup. Chainalysis researchers say Xinbi duplicated crypto payment infrastructure on an alternative messaging app and launched its own payment app called XinbiPay. That makes taking the operation offline harder.
Telegram channels tied to Xinbi reportedly include thousands of members, with at least one channel around 175,000 subscribers.
Global enforcement, messy reality
Governments have stepped up enforcement. The US and UK have issued sanctions, law enforcement has raided compounds, and there have been arrests linked to large scam networks. Still, the money involved and political connections around some of these operations allow them to buy new technology and rebuild.
Official perspectives
- UK officials said the sanctions send a clear message that those who run scam centers will face consequences.
- Tom Robinson, cofounder and chief scientist at Elliptic, noted sanctions will complicate Xinbi's ability to move and spend crypto, though the platform has demonstrated resilience.
- Gregory Heeb from the FBI said reported losses from scamming have risen sharply. Preliminary US figures show about 456,000 digital scam complaints in 2025, with reported losses above $17.7 billion.
- Karen Seifert from the United States Attorney's Office highlighted a practical challenge: the people running scam compounds are often separate from the networks laundering the money, so investigators must pursue two different targets.
- John Wojcik, a threat researcher, warned that the core weakness is not just the scams themselves but the sophisticated underground banking and laundering networks that support them.
Bottom line
The UK sanctions on Xinbi are a significant step and could disrupt parts of a sprawling illicit system. But Xinbi has already shown it can adapt: moving across platforms, rebuilding channels, and building its own payment tools. Taking down that kind of infrastructure will be a long effort that requires coordinated action across governments and industry.
