Criminal hackers gained access to files that include the sensitive personal data — Social Security numbers, birth dates and home addresses — of 143 million Americans by penetrating a Web-based application for Equifax, the credit reporting agency said Thursday.

The breach, which the company said began in May, was discovered in July. Though Equifax said in a statement that “core database” were not penetrated, the attackers did gain access to a wide range of data for what appears to be a majority of American adults and some British and Canadian consumers as well.
