Equifax Inc. (NYSE:EFX) stock tumbled 15% Friday morning as Wall Street came down hard on the company. The reason? The credit monitoring firm announced that hackers stole records containing personal information on 143 million of its customers in the US. In addition, Bloomberg revealed that three of the company’s senior executives, including the company’s chief financial office, sold nearly $1.8 million in shares after the company learned of a massive hack.

Equifax CEO Richard F. Smith commented, “This is clearly a disappointing event for our company, and one that strikes at the heart of who we are and what we do. I apologize to consumers and our business customers for the concern and frustration this causes […] We pride ourselves on being a leader in managing and protecting data, and we are conducting a thorough review of our overall security operations. We also are focused on consumer protection and have developed a comprehensive portfolio of services to support all U.S. consumers, regardless of whether they were impacted by this incident.”

Smith continued, “I’ve told our entire team that our goal can’t be simply to fix the problem and move on.  Confronting cybersecurity risks is a daily fight. While we’ve made significant investments in data security, we recognize we must do more. And we will.”
