A Chinese-language service on Telegram operated as an all-purpose underground bazaar offering cash-out services to scammers, money laundering for North Korean hackers, and more.
Xinbi Guarantee, a U.S.-registered company, facilitated $8.4 billion in transactions through its Telegram-based marketplace, mainly from money stolen from scam victims.
The marketplace also featured services for child-bearing surrogacy, harassment-for-hire, sex trafficking, and other criminal activities.
