Attackers are always looking for creative ways to send large amount of spam to victims. A short-lived, but widespread Google Drive themed phishing campaign has affected a large number of users across a variety of verticals. This campaign would be bcc’d to a target while being sent to hhhhhhhhhhhhhhhh@mailinator[.]com, to make this email appear legitimate the sender would be someone who had the target in their address book.

Mailinator is a “free, public, email system where you can use any inbox you want,” often used for throwaway accounts. In this instance, the Mailinator inbox in question could have been used by the spammer to monitor whether or not the email was successfully sent. The use of Mailinator, however, is not what made this campaign unique.
