Personal data of nearly one billion people have been hacked by a caliginous company that is untraceable since the incident has happened. 

The database contains email addresses of around 982 million people. According to researchers, this could be the ‘biggest and most comprehensive email database' breaches ever.

The pieces of information that have been compromised includes names, gender, date of birth, employer, details of social media accounts and home addresses. 

The database was created by Verifications.io, and it did not have any kind of security measure. 

The firm was a marketing company, that offered a service of email validation to another marketing firm. The service includes authentication of email addresses. 

The company took down its website after the leak was uncovered and they have refused requests for a comment on the situation.

The motive behind the hack is not clear as the backers are maintaining their anonymity because of dubious tactics used by them to offer their service. 

Moreover, they have refused to comment on the situation.
