Equifax Filing Sheds Light on 2017 Data Breach Carnage

In a new filing with Securities and Exchange Commission, Equifax executives are offering a greater level of detail of the 2017 data breach that affected more than 146 million customers.

The 2017 data breach at Equifax, which affected more than 146 million of the company's customers, is considered one of the largest incidents of its kind. Now, new documents are laying bare how vast the breach actually was.

In response to several congressional investigations about the data breach, Equifax has filed new paperwork with the US Securities and Exchange Commission that offers a staggering amount of detail about how many records were exposed last year.

Overall, the company states that 146.6 million customers were affected by the breach.

Equifax initially claimed about 143 million customers were compromised, but that number has steadily risen over the ensuing months.

The original breach occurred when a person or persons took advantage of a known vulnerability in Apache Struts CVE-2017-5638, according to numerous reports. The patch was available for this particular flaw but it appears that the company did not update its software.

As a result, millions of records were taken.

"The attackers stole consumer records from a number of database tables with different schemas, and the data elements stolen were not consistently labeled," according to the May 7 filing. "For example, not every database table contained a field for driver's license number, and for more common elements like first name, one table may have labeled the column containing first name as 'FIRSTNAME,' another may have used 'USER_FIRST_NAME,' and a third may have used 'FIRST_NM.'"

Here's how many records were taken:

  • Names: 146.6 million
  • Date of Birth: 146.6 million
  • Social Security Number: 145.5 million
  • Address: 99 million
  • Gender: 27.3 million
  • Phone Number: 20.3 million
  • Driver's License Number: 17.6 million
  • Email Address: 1.8 million
  • Payment Card Number and expiration Date: 209,000
  • Tax ID: 97,500
  • Driver's License State: 27,000

In addition to these records, Equifax believes that the attackers also accessed data, specifically images, uploaded through the company's online dispute portal, which affected about 182,000 US customers. These were mainly government-issued documents and included 38,000 driver's licenses, 12,000 Social Security or Taxpayer ID cards, 3,200 passports or passport cards, and 3,000 "other" records.

The fallout from the breach is continuing.

In March, the SEC, along with the US Attorney's Office for the Northern District of Georgia, charged Equifax's former US CIO with insider trading and other offenses. Specifically, an indictment charged that Jun Ying knew about the breach and sold his company stock before the incident was made public. (See Former Equifax CIO Charged With Insider Trading.)

The Equifax and other data breaches also forced the SEC to update its rules about public disclosures of cybercrimes. (See Equifax, Intel Help Spur SEC to Update Cybersecurity Regulations.)
