Equifax announced a cybersecurity incident potentially impacting approximately 143 million U.S. consumers; but no evidence of unauthorized access to core consumer or commercial credit reporting databases.
Criminals exploited a U.S. website application vulnerability to gain access to certain files. Based on the company's investigation, the unauthorized access occurred from mid-May through July 2017. The company has found no evidence of unauthorized activity on Equifax's core consumer or commercial credit reporting databases. The information accessed primarily includes names, Social Security numbers, birth dates, addresses and, in some instances, driver's license numbers.
In addition, 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, were accessed. As part of its investigation of this application vulnerability, Equifax also identified unauthorized access to limited personal information for certain UK and Canadian residents. Equifax will work with UK and Canadian regulators to determine appropriate next steps. The company has found no evidence that personal information of consumers in any other country has been impacted.
