In an update from the Equifax data breach in 2017, the company reported to the Securities and Exchange Commission that while no new breaches occurred and no new customers were affected, a total of 2.4 million personally identifiable information (PII) were collected from the 2017 attack. The image storage server where customers upload scans of documents for their online dispute portal was also hacked, which included passports and other government-issued IDs.
Equifax submitted the report at the request of the congressional committees investigating the cybersecurity incident to determine the depth and extent of the breach. The initial report in September 2017 estimated that the breach exposed records of 145.5 million US citizens and 15.2 million in the UK. After organizing and classifying their internal databases, analysis yielded that the PII collected by the hackers include dates of birth, social security numbers (SSN), addresses, phone numbers, email addresses, driver’s license numbers, tax identification numbers, and credit card data, among others. The report filed late last week yielded more specific details:
|Data Element Stolen||Approx. Number of Affected US Consumers|
|Date of Birth||146.6 million|
|Address Information||99 million|
|Phone Number||20.3 million|
|Driver's License Number||17.6 million|
|Email (w/o credentials)||1.8 million|
|Payment Card No. and Expiration Date||209,000|
|Driver's License State||27,000|
The report states that no additional breaches and no additional customers were affected since the September 2017 announcement. However, aside from the database information accessed by the cybercriminals, the online dispute portal was also breached, exposing images uploaded by approximately 182,000 US consumers. From the company review details the approximate number of government-issued IDs uploaded:
|Government-Issued ID||Approx. Number of Images Affected|
|SS or Tax ID Card||12,000|
|Passport or Passport Card||3,200|
|Others (Military IDs, Resident Alien Cards, Stte-Issued IDs)||3,000|
While individual customers were initially notified after the public announcement late last year, Equifax wrote that the affected consumers will receive notifications by US Postal mail, identifying the PII included in the breach, except for those whose gender, phone numbers and email addresses were collected as US notification laws do not require it. The company also announced on their website that they will be offering identity theft protection and credit file monitoring to affected customers at no cost. Customers can also access the website for the “Am I Impacted” tool to find out if their information is among the list of affected records.
