### U.S. Authorities Crack Down on Xinbi Guarantee: $52.8 Million in Crypto Seized
In a major blow to illicit digital marketplaces, the U.S. Secret Service successfully intercepted $52.8 million in USDT on September 8. The operation targeted 52 distinct digital wallets associated with Xinbi Guarantee, a notorious Chinese-language platform operating via Telegram that provides infrastructure for global fraud operations.
#### Strategic Intelligence and Enforcement
The success of this operation relied heavily on a partnership with Elliptic, a leading blockchain analytics firm. By leveraging advanced forensic tracking, authorities were able to map out the complex wallet infrastructure Xinbi utilized to facilitate its criminal activities.
“Our team has been monitoring Xinbi’s operations for years,” Elliptic noted in a recent statement. “The intelligence we provided was instrumental in both the freezing of these assets and the subsequent sanctions leveled against the organization by the U.S. government.”
#### A Broader Regulatory Offensive
The freeze coincided with a significant escalation from the U.S. Treasury’s Office of Foreign Assets Control (OFAC), which officially designated Xinbi as a “significant transnational criminal organization.” This move is part of a wider, aggressive campaign by the Department of Justice’s Scam Center Strike Force. Since its inception in November 2025, the task force has successfully seized approximately $938 million in illicit funds, signaling a new era of high-stakes enforcement against crypto-enabled crime.
#### The Cat-and-Mouse Game of Digital Assets
Despite the enforcement action, Xinbi has pushed back, labeling the government’s intervention as “arbitrary.” In a desperate attempt to circumvent future restrictions, the platform attempted to shift $2.8 million of its remaining holdings into USDD.
This maneuver highlights a growing trend in cybercrime: moving assets into stablecoins that lack the centralized “freeze” functionality inherent in assets like USDT. However, experts point out that this is a temporary fix at best, as USDD reserves are still partially collateralized by USDT, leaving the funds vulnerable to broader regulatory pressure.
