‘Is my Email Hacked’? Latest data breach risks 900 MILLION emails


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.

Major Concerns after the Data Breach

The breach is not only one of the largest reported breach ever the amount of data it holds is concerning.

The database not only included email address but it has names, gender, date of birth, employer, social media accounts and home and work address. What is more concerning that database also held the business intelligence data income of the employees.

When the researcher duo reported the leak to the company they took the database offline and removed their traces from it.

The data does not contain any credit card or password information. The password found in the database were of internal infrastructure.

When data is available to the scammers in plain text and well aggregated it can be more dangerously used.

What does do? is an email validator which means that they check that the address a user is entering while signup for a service is valid or not.

Even though several companies have there own in-house mechanisms but they go towards a third-party system like to avoid being blacklisted by spam filters.

Essentially validation service sends out spam to verify the mailing list of their client so that client can evade the spam filter of email providers like Gmail.
