#Blockchain Security Alert# Recently, at least three Coinbase users and one cryptocurrency user have been attacked by scammers posing as Coinbase, and one of the victims was defrauded of up to $1.7 million in crypto assets. The scammers impersonated the Coinbase security team and tricked the victims into sharing their mnemonics via email and phone. Although the victim realized that this was "unsafe", he still entered "partial" mnemonics. As a result, a few hours later, $1.7 million in crypto assets in his wallet were stolen. Everyone must be vigilant during the transaction and never disclose personal information and mnemonics at will. Have you encountered similar scams?
