Scammers posing as Coinbase representatives have reportedly stolen $1.7 million from at least one victim amid a string of attacks over the last week. The scammers use real phone numbers and fake Coinbase emails to trick users into revealing sensitive information. Four users have been targeted in these attacks, which involve sending fake emails and making urgent requests for seed phrases on fraudulent websites. Users are advised to verify URLs, enable two-factor authentication, and avoid links from unknown sources to protect their assets. These scams have exploited security vulnerabilities and have impacted Coinbase's reputation, with the company's stock symbol $COIN being mentioned in relation to the incidents.
