ChainCatcher reported that at least three Coinbase users and one cryptocurrency user were targeted by scammers posing as Coinbase over the past week, with one victim being defrauded of $1.7 million. The scammers directed the victim to a website and asked them to enter a mnemonic phrase to stop trading. The victim knew it was unsafe, but still entered part of the phrase but did not submit it. A few hours later, the victim's wallet was stolen from $1.7 million in crypto assets.
