A KrebsOnSecurity series on how easy big-three credit bureau Equifax makes it to get detailed salary history data on tens of millions of Americans apparently inspired a deeper dive on the subject by Fast Company, which examined how this Equifax division has been one of the company’s best investments. In this post, I’ll show you how to opt out of yet another Equifax service that makes money at the expense of your privacy.
Equifax has re-opened a Web site that lets anyone look up the salary history of a large portion of the American workforce using little more than a person’s Social Security number and their date of birth. The big-three credit bureau took the site down just hours after I wrote about it on Oct. 8, and began restoring the site eight days later saying it had added unspecified “security enhancements.”
In May, KrebsOnSecurity broke a story about lax security at a payroll division of big-three credit bureau Equifax that let identity thieves access personal and financial data on an unknown number of Americans. Incredibly, this same division makes it simple to access detailed salary and employment history on a large portion of Americans using little more than someone’s Social Security number and date of birth — both data elements that were stolen in the recent breach at Equifax.
Maybe you’ve been feeling left out because you weren’t among the lucky few hundred million or billion who had their personal information stolen in either the Equifax or Yahoo! breaches. Well buck up, camper: Both companies took steps to make you feel better today.
Yahoo! announced that, our bad!: It wasn’t just one billion users who had their account information filched in its record-breaking 2013 data breach. It was more like three billion (read: all) users. Meanwhile, big three credit bureau Equifax added 2.5 million more victims to its roster of 143 million Americans who had their Social Security numbers and other personal data filched in a breach earlier this year. At the same time, Equifax’s erstwhile CEO informed Congress that the breach was the result of even more bone-headed security than was first disclosed.
To those still feeling left out by either company after this spate of news, I have only one thing to say (although I feel a bit like a broken record in repeating this): Assume you’re compromised, and take steps accordingly.
Identity thieves who specialize in tax refund fraud had big help this past tax year from Equifax, one of the nation’s largest consumer data brokers and credit bureaus. The trouble stems from TALX, an Equifax subsidiary that provides online payroll, HR and tax services. Equifax says crooks were able to reset the 4-digit PIN given to customer employees as a password and then steal W-2 tax data after successfully answering personal questions about those employees.
In a boilerplate text sent to several affected customers, Equifax said the unauthorized access to customers’ employee tax records happened between April 17, 2016 and March 29, 2017.
Beyond that, the extent of the fraud perpetrated with the help of hacked TALX accounts is unclear, and Equifax refused requests to say how many consumers or payroll service customers may have been impacted by the authentication weaknesses.
