NEW YORK – Having to get a background check done is bad enough as it is but what if all of your personal and employment information was left exposed online for anyone to access? Well, that’s exactly what just happened for at least 100 million Americans.

Unlike with data breaches which are usually the work of hackers, data leaks occur when a company fails to properly secure the data points it has on customers or in this case, one third of the entire U.S. population.

As reported by Cybernews, its security researchers recently discovered a worrying data leak at a company called MC2 Data which operates a number of public record and background check sites including PrivateRecords.net, PrivateReports, PeopleSearcher, ThePeopleSearchers and PeopleSearch USA.

Here’s everything you need to know about this massive new data leak including all of the information that was exposed along with some tips and tricks to help keep you safe from hackers trying to use this leaked info in their attacks.
