Last year's Equifax security breach was reportedly worse than the company said it was.
The Wall Street Journal reports documents sent to the Senate Banking Committee by Equifax say hackers accessed customers' tax identification numbers, email addresses and driver's license information, besides just driver's license numbers as Equifax disclosed.
Here's a little background: In September, Equifax said a cyberattack exposed more than 100 million Americans' names, Social Security numbers and other sensitive information.
An Equifax spokeswoman told the Journal the company has "complied with applicable notification requirements in the disclosure process."
Banking committee member Sen. Elizabeth Warren sent a letter to the interim CEO of Equifax on Friday. She asked the company to send her and the committee a letter detailing "all data elements that Equifax has confirmed were accessed by hackers in the breach" within a week.
