Sophos detailed a Cambodia-linked cryptocurrency fraud operation dubbed Sour Grapes that used misdirected SMS messages and long-running Telegram chats to lure victims into a classic pig-butchering scam. Operators posed as a fabricated woman named "Harley" and directed targets to fake crypto trading and liquidity-mining platforms that impersonated legitimate financial and cryptocurrency brands, steering deposits through Crypto.com-funded transactions before moving funds across rapidly changing wallets and domains.
Investigators tied the infrastructure to Chinese-speaking operators and identified evidence pointing to Phnom Penh and Sihanoukville, alongside more than 500 related domains built from nearly identical scam kits. Blockchain analysis found the operation collected more than $3 million in cryptocurrency over roughly five months, with some funds traced to Tokenlon according to Chainalysis, underscoring how industrialized scam compounds in Southeast Asia continue to scale social-engineering fraud through reusable infrastructure and fast-moving payment channels.
