National Public Data, a company that provides background-checks, is facing a class action lawsuit alleging the personal information of nearly 3 billion unsuspecting people was exposed. If confirmed, the suspected data breach from April could be among the biggest. As most of the personal information gathered by NPD is scraped from non-public sources, victims didn’t knowingly provide their info to NPD, which may include Social Security numbers, names, addresses, and more. If exploited, cybercriminals can use this information to commit identity theft.
