The bad guys are recycling a very old idea and put some modern lipstick on it. Instead of winning the lottery in Nigeria, you have now been given 30 bucks in Bitcoins. Just sign in to view the transaction and who your mystery benefactor is. Yeah, sure.

John OBrien, a spokesperson for Coinbase, wrote in an email that the phishing message had a few warning signs: "[T]here are a few red flags. ‘Hi,’ (not addressed to anyone) and ‘from an external account’ (not from anyone). Additionally the link will not take you to Coinbase.com."
