Do not reply to this e-mail”
Coinbase executives have informed alarmed users on Twitter and Reddit that scammers managed to gain access to their secondary e-mail provider, Sendgrid. The leaked recipient e-mails however didn’t proceed from a breach of their databases and thus far several users have reported being contacted on addresses they’d only used on LocalBitcoins and Bitcoin24 while many recipients aren’t even registered at Coinbase.
Admins from the site have already taken steps to stop further activity from the scammers as well as disabling their Sendgrid account while they investigate the matter.
Each e-mail includes an unique Bitcoin address, so at the moment it’s impossible to estimate what percentage of users may have fallen for the scam.
