A security researcher duo named Bob Diachenko and Vinny Troia recently found out a data breach, an unencrypted and publicly accessible MongoDB database sizing around 150 gigs which contained detail information in plain text about millions of individuals and companies.

The source of this leak or hack appears to be an email verification company called verification.io. Verification.io had more than 982 million email address on its website.
