The U.S. Treasury reported that North Korean hackers used Xinbi Guarantee, an illicit marketplace that supplied escrow and transactional services to scam operators, money-laundering networks, and cybercrime syndicates. OFAC sanctioned Xinbi Guarantee and two supporting application developers, while the Justice Department seized associated infrastructure and digital-asset wallets. Xinbi reportedly processed more than $24 billion in digital assets and fiat currency and offered encrypted coordination and cryptocurrency-payment services through SafeW and XinbiPay.
