币界网报道：A new report reveals that "pig butchering" scams, a sophisticated form of crypto fraud, are costing victims over $44 billion annually, with major global banks unwittingly facilitating these transactions. The scams involve fraudsters building trust with victims through social media or dating apps before convincing them to invest in fake crypto schemes. Once funds are deposited into fraudulent platforms, victims are unable to withdraw their money. Researchers found that these scams often involve transactions through prominent banks like JPMorgan Chase, Bank of America, and HSBC, with funds frequently moving to crypto exchanges such as Binance. The scammers typically convert stolen crypto into Tether (USDT) to obscure the money trail. Law enforcement agencies face challenges in tracking these funds due to the cross-border nature of the crimes and the use of crypto mixing services. Experts warn that the actual losses may be higher as many victims don't report the crimes due to embarrassment. The report calls for increased cooperation between banks, crypto exchanges, and regulators to combat these growing scams. Some banks have begun implementing stricter monitoring of transactions linked to known crypto fraud patterns. Meanwhile, blockchain analytics firms are developing new tools to help identify and flag suspicious transactions associated with pig butchering schemes.
