U.S. Seizes $52.8 Million and Shuts Down Xinbi Guarantee Scam Platform

Federal officials announced the dismantling of Xinbi Guarantee, an online marketplace that investigators say was a hub for cyber‑fraud operations, and reported the seizure of $52.8 million from 52 digital wallets linked to the site.

According to the announcement, Xinbi Guarantee functioned as a broker for illicit services, connecting scammers with victims and facilitating the movement of cryptocurrency proceeds. The platform allegedly offered tools and instructions that helped actors launch phishing attacks, ransomware campaigns, and other forms of online theft, effectively acting as a financial conduit for the broader cyber‑scam economy.

The seizure was carried out by a coalition of agencies that included the Treasury Department's Office of Foreign Assets Control, the Department of Justice and law‑enforcement partners abroad. Investigators traced the flow of funds through blockchain analysis, identifying a network of wallets that moved money in and out of the marketplace. By freezing those accounts, authorities immobilized assets that had been generated from countless fraudulent schemes.

The action follows a series of high‑profile crackdowns on cryptocurrency‑enabled fraud that have intensified over the past two years. Regulators have increasingly focused on platforms that provide anonymity or facilitate rapid transfers, arguing that such services can be exploited to launder proceeds from ransomware attacks, business email compromise and other cybercrimes. The Xinbi Guarantee case adds to recent seizures involving darknet markets and illicit token exchanges.

Officials said the frozen funds could eventually be used to compensate victims, though the process may be lengthy due to the complexities of tracing individual losses and the legal steps required to redistribute seized assets. Victims of scams linked to the marketplace have been urged to file claims through the appropriate channels as authorities continue to assess the total impact.

Legal experts anticipate that the disruption of Xinbi Guarantee will prompt further investigations into related networks and may lead to additional indictments. The Treasury department indicated that the seizure sends a clear message to operators of similar platforms that illicit activity on the blockchain will not be tolerated, and that coordinated international efforts will remain a cornerstone of future enforcement strategies.
