The Equifax Data Breach: A Case Study in Data Security Failure and its Aftermath

The 2017 Equifax data breach remains one of the most significant data breaches in history, exposing the personal information of nearly 148 million people. This analysis examines the breach, its impact on Equifax, the resulting lawsuits, and the crucial lessons learned for organizations handling sensitive data.

What Happened: A Summary of the Equifax Breach

Attackers exploited a known vulnerability in the Apache Struts web framework used by Equifax's online dispute portal.

• Timeline: The breach occurred over several months, highlighting the importance of continuous monitoring and prompt incident response.
• Data Exposed: Sensitive personal information compromised included:
  • Social Security numbers
  • Birth dates
  • Addresses
  • Driver's license numbers
  • Credit card numbers (for some individuals)
