The U.S. Treasury Department sanctioned Xinbi Guarantee, a Chinese-language cybercrime marketplace accused of supporting Southeast Asian scam compounds, while the Justice Department seized two cryptocurrency wallets holding about $12 million and sought restraints on 47 more. Authorities said the combined action restrained more than $52 million, and a federal court authorized the seizure of Telegram channels tied to the platform on Sept. 7. Treasury also designated SafeW Technology and Anwen Technology, which provided messaging and payment infrastructure used by Xinbi as it shifted merchant coordination to SafeW and introduced XinbiPay, also known as NewPay. Treasury said Xinbi processed more than $24 billion in digital assets and fiat currency since emerging around 2022, while TRM Labs Global Head of Policy Ari Redbord separately estimated that it moved more than $36 billion. Chainalysis said North Korea-linked actors laundered tens of millions of dollars in stolen cryptocurrency through Xinbi vendor Black U, exchanging traceable stolen assets for stablecoins associated with pig-butchering and romance-scam proceeds before cashing out through unlicensed over-the-counter platforms. Bitrace recorded increased withdrawals from a Xinbi sub-guarantee platform after the sanctions, with USDT outflows rising to about $1.28 million on Sept. 8 and $1.81 million on Sept. 9, while rival Fulilai Guarantee removed publicly listed laundering merchants and its wallet recorded about $9.3 million in outflows.
