A database owned by the email delivery and marketing firm Maropost was reportedly found open and unsecured exposing about 95 million customer records. Researchers at CyberNews initially found the database in early February noting it contained 19.2 million unique email addresses and marketing logs containing the relevant metadata for these emails, such as the exact date and time the emails were sent, who sent them and to whom. The data resided on a Google Cloud server and was locked down on April 1. CyberNews claimed it tried multiple times using email, social media and the telephone to inform Maropost of the issue.
