WASHINGTON – Four members of the Chinese military have been charged with breaking into the computer networks of the Equifax credit reporting agency and stealing the personal information of tens of millions of Americans, the Justice Department said Monday, blaming Beijing for one of the largest hacks in history to target consumer data. The hackers in the 2017 breach stole the personal information of roughly 145 million Americans, collecting names, addresses, Social Security and driver’s license numbers and other data stored in the company’s databases.
