Chinese-language online black markets have emerged as some of the largest facilitators of cybercrime in recent history, processing tens of billions of dollars in illicit funds annually. These underground marketplaces provide a range of services that enable large-scale scam operations, human trafficking, and money laundering worldwide. They trade in stolen personal data, launder money, and sometimes even supply physical restraints such as electrified shackles to enforce control over victims. Recently, authorities in the United Kingdom have taken a significant step against one of the largest such marketplaces, Xinbi Guarantee, by imposing financial sanctions that could severely limit its operations.
On Thursday, the UK's Foreign, Commonwealth and Development Office (commonly called the Foreign Office) announced sanctions targeting Xinbi Guarantee, an online cryptocurrency marketplace that has operated extensively through Telegram channels and accounts. Despite previous efforts to disrupt it, Xinbi has been linked to billions of dollars in cryptocurrency transactions and remained resilient to takedown attempts. The new sanctions signal a concerted effort by UK authorities to curb the scale and influence of this marketplace.
In conjunction with the sanctions against Xinbi, British officials also penalized several individuals allegedly connected to large-scale scam compounds in Cambodia, including the notorious #8 Park compound, which reportedly housed up to 20,000 people. The UK government additionally seized several properties in London tied to these individuals, including a £9 million penthouse. Foreign Office minister Stephen Doughty emphasized that the sanctions send a "clear message" that those operating scam compounds will face consequences. This action follows a wave of penalties from both the US and UK last October targeting Cambodian-linked scamming operations.
Over the past decade, hundreds of thousands of human trafficking victims have been forced to work in compounds across Cambodia and Southeast Asia, orchestrating online scams around the clock. These scams frequently involve fraudulent cryptocurrency investment schemes and romance scams designed to defraud unsuspecting victims. Many of these operations have ties to Chinese organized crime groups and rely heavily on secondary services and marketplaces that provide the necessary tools, infrastructure, and laundering services to sustain their illicit enterprises. Xinbi Guarantee is among the largest of these marketplaces, especially after the Huione Group-a similar operation-was sanctioned last year.
According to the UK's sanctions register, Xinbi has "profited financially or otherwise obtained a benefit from human rights abuses," referring to reports of brutal treatment and torture within scam compounds in Southeast Asia. The sanctions highlight Xinbi's role in enabling and profiting from these centers, effectively making it complicit in the associated abuses.
Experts in cryptocurrency tracing have noted the impact of these sanctions. Tom Robinson, chief scientist and cofounder of the crypto-tracing company Elliptic, explained to WIRED that the sanctions will complicate Xinbi's ability to spend or exchange cryptocurrency processed through its marketplace. Elliptic's analysis last year revealed that Xinbi Guarantee facilitated at least $8.4 billion in transactions since 2022, with the majority likely representing stolen funds from online scam victims. Besides laundering money, the platform also sells essential technology, personal data, and money-laundering services that scam operators rely on.
Despite efforts to disrupt Xinbi, including Telegram's removal of channels linked to both Huione and Xinbi following WIRED's reporting in May, Xinbi has demonstrated remarkable resilience. It quickly rebuilt its presence on Telegram and diversified its infrastructure to withstand takedown attempts. Robinson noted that Xinbi not only recovered but also expanded its market share after Huione Guarantee and similar marketplaces were shut down. He now estimates that Xinbi and its associated merchants have processed nearly $19.7 billion in transactions.
Xinbi's website, included in the recent UK sanctions list, promotes several Telegram channels with thousands of members, including one with approximately 175,000 subscribers. Telegram has not publicly responded to inquiries regarding the sanctions or the channels linked to Xinbi. Attempts to contact Xinbi-related Telegram accounts for comment similarly received no immediate response.
Further analysis from Chainalysis, another prominent crypto-tracing firm, corroborates Xinbi's growth and adaptation. The firm reports that Xinbi has taken additional steps to safeguard its operations, processing roughly $19.9 billion between 2021 and 2025. Chainalysis researchers also identified that Xinbi has duplicated some of its cryptocurrency payment infrastructure on alternative messaging platforms and launched its own payment app, XinbiPay. These moves suggest an effort to build proprietary financial infrastructure that can withstand disruptions targeting other illicit services.
Globally, governments have increasingly intensified enforcement efforts against various components of the scam ecosystem. Actions include sanctioning cryptocurrency marketplaces, disrupting crypto-based money laundering networks, and raiding physical scam centers. Following the US-UK sanctions last year and the arrest of alleged criminal mastermind Chen Zhi by Chinese authorities, Cambodia has moved to shut down hundreds of scam compounds operating in the region.
Nevertheless, the vast sums of money flowing through these criminal networks, combined with close political ties, allow these operations to invest in new technologies, acquire infrastructure, and build resilience to enforcement efforts. This adaptability has made it difficult for even large-scale international collaborations to significantly diminish the scale and influence of global scam operations.
At a recent hearing before the United States Senate Joint Economic Committee, FBI Deputy Assistant Director Gregory Heeb highlighted that scamming remains vastly underreported in the US, despite reported losses increasing by approximately 350 percent since 2019. Preliminary data for 2025 indicate the FBI's Internet Crime Complaint Center received about 456,000 digital scam complaints, with reported losses exceeding $17.7 billion.
Karen Seifert, director of the Scam Center Strike Force within the US Attorney's Office for the District of Columbia, explained during the hearing that the money laundering networks are largely separate from the scam compounds themselves. This separation complicates enforcement efforts, as cracking down on the leadership of scam compounds does not necessarily expose the money laundering infrastructure. As a result, authorities allocate substantial resources to tackle both sides of the problem.
John Wojcik, a threat researcher at security firm Infoblox and a former official at the United Nations Office on Drugs and Crime specializing in scamming operations, described the scale of scams, money laundering, and related online casinos operating out of Asia as unprecedented. He emphasized that the critical vulnerability lies not within the cybercrime and scam operations themselves, but in the underground banking and money laundering infrastructure that fuels them.
According to Wojcik, Asian money laundering organizations are global leaders in this illicit space, and the extent of their infiltration into financial systems and economies worldwide is only beginning to be fully understood. This insight underscores the complexity of dismantling these networks and the importance of targeting their financial underpinnings to effectively combat the global scamming epidemic.
In summary, the recent UK sanctions against Xinbi Guarantee represent a significant development in the ongoing battle against online black markets that facilitate cybercrime on a massive scale. However, the resilience and adaptability of these marketplaces, combined with the sprawling, interconnected nature of scam operations and their supporting money laundering infrastructure, present formidable challenges for law enforcement worldwide. Continued international cooperation and innovative enforcement strategies will be essential to disrupt these criminal networks and protect victims from their harmful impacts.
