• Regulatory Compliance: Adhere to data protection regulations such as GDPR to safeguard user information.

The Financial Services Fiasco: The Equifax Breach (2017)

Background

Equifax, one of the three major credit reporting agencies in the United States, collects and maintains sensitive financial information for millions of individuals. In 2017, Equifax suffered a massive data breach that exposed the personal information of 147 million people.

The Hack

The breach occurred when attackers exploited a vulnerability in Equifax’s Apache Struts web application framework. Despite knowing about a patch’s vulnerability and availability, Equifax failed to apply it on time. The attackers used this vulnerability to access Equifax’s network, where they spent several months exfiltrating data.

Methods Used by Attackers

The attackers utilized an Apache Struts vulnerability (CVE-2017-5638) for remote code execution. By exploiting this vulnerability, they bypassed security controls and gained unauthorized access to sensitive data, including Social Security numbers, birth dates, addresses, and driver’s license numbers.

Consequences

The consequences of the Equifax breach were severe, including financial losses estimated at over $1.4 billion due to legal fees, settlements, and security improvements. Additionally, Equifax faced regulatory penalties and a significant loss of consumer trust, leading to long-term reputational damage.

Lessons Learned
