Equifax CEO retires after security breach

Equifax chairman and CEO Richard Smith retired today after his company suffered a major security breach earlier this month that exposed personal financial information for approximately 143 million Americans.

The details: The information accessed in the three-month-long hack included customers' names, birth dates, addresses, social security numbers, and driver's license numbers. Close to 209,000 consumers' credit card information was accessed. Smith's exit follows two others. Equifax's chief information officer and chief security officer stepped down earlier this month.
