Equifax, one of the largest credit reporting agencies, suffered one of the most severe data breaches in history in 2017. Hackers exploited a vulnerability in the company’s dispute resolution portal, gaining unauthorized access to highly sensitive personal and financial data. The breach exposed the records of approximately **147 million people**, including **Social Security numbers, birth dates, addresses, credit card numbers, and in some cases, driver’s license details**. The stolen data was never publicly leaked or sold on dark web marketplaces, suggesting potential state-sponsored involvement (e.g., espionage or intelligence gathering). However, the sheer scale of the breach—affecting nearly half the U.S. population—led to massive reputational damage, regulatory fines (including a **$700 million settlement**), and long-term distrust in Equifax’s security practices. The incident also triggered widespread identity theft risks, fraud alerts, and credit freezes for millions of victims. Unlike criminal hacker-driven breaches where data is monetized, Equifax’s case highlighted how **unseen exploitation of vulnerabilities** can have catastrophic, long-term consequences without immediate public data dumps. The breach remains a benchmark for corporate negligence in cybersecurity, exposing systemic failures in patch management and data protection protocols.
