Blockchain investigator ZachXBT disclosed that last week, Coinbase users lost $45 million again due to a well-orchestrated social engineering fraud. Scammers induced victims to transfer assets into fake wallets by forging emails and impersonating Coinbase over the phone. Multiple related wallets have been tracked, with one wallet receiving funds from dozens of victims. ZachXBT criticized Coinbase for failing to freeze these addresses in a timely manner and suggested improvements to the security verification process and international user support.
