After exposing the names, Social Security numbers, birth dates, and more of 143 million Americans in a massive data breach, Equifax is now facing a potentially billion-dollar class-action lawsuit. USA Today reports a lawsuit was filed against the credit monitoring company Thursday in Oregon on behalf of customers Mary McHill and Brook Reinhard. The lawsuit accuses Equifax of choosing money over proper data security measures. "In an attempt to increase profits, Equifax negligently failed to maintain adequate technological safeguards to protect Ms. McHill and Mr. Reinhard's information from unauthorized access by hackers," attorney Michael Fuller wrote in the complaint. An attorney connected to the lawsuit tells Bloomberg it will seek up to $70 billion in damages. (More Equifax stories.)
