Equifax Data Breach

Credit reporting agency Equifax announced a massive data breach on 7 September that it says could potentially impact 143 million US customers. Equifax is one of the three largest US credit bureaus that collects and maintains consumer financial data for hundreds of millions of people in the US and Canada.

According to an AFP article, “Equifax said that a hack it learned about on July 29 had the potential to affect 143 million US customers, and involved some data for British and Canadian residents.” A statement on Equifax’s informational website dedicated to updates on the breach stated that “the unauthorized access occurred from mid-May through July 2017,” and that the information accessed included “names, Social Security numbers, birth dates, addresses and, in some instances, driver’s license numbers” as well as “credit card numbers for approximately 209,000 U.S. consumers, and certain dispute documents with personal identifying information for approximately 182,000 U.S. consumers.” Personal information of UK and Canadian residents was also accessed.

Equifax’s handling of the data breach has been criticized because of the 41 day delay between their discovery of the breach on 29 July and their disclosure of the breach on 7 September.

News that three Equifax senior executives, including Chief Financial Officer John Gamble, sold Equifax stock after the breach was discovered but before the breach was publicly announced only intensified public dissatisfaction with how the company has dealt with one of the largest and most damaging data breaches to date.

The Yahoo data breaches of 2013 and 2014 affected a greater number of users accounts, over 1 billion, but the data types exposed by this Equifax breach, a package of personally identifiable information including full social security number and possibly credit card numbers, makes this breach potentially more damaging than the larger Yahoo breach.
