Blockchain investigator ZachXBT revealed that Coinbase users lost another $45 million last week due to sophisticated social engineering scams. Victims were tricked into transferring assets to fake wallets via phishing emails and spoofed calls impersonating Coinbase. Several linked wallets were identified, including one that received funds from dozens of victims. ZachXBT criticized Coinbase for failing to freeze flagged wallets and recommended key changes to improve security, verification, and global user support.
