Equifax, one of the United States' largest credit reporting agencies, is reporting a three-month-long cybersecurity incident that may have affected 143 million U.S. customers, per Bloomberg. The information accessed in the potential breach includes names, birth dates, addresses, social security numbers, and driver's license numbers. Close to 209,000 customers' credit card information was accessed.
Why it matters: 143 million is half the U.S. population.
More, from Bloomberg: "Three Equifax Inc. senior executives sold shares worth almost $1.8 million in the days after the company discovered the security breach."
