Hackers stole the personal data of 57 million customers and drivers from Uber Technologies Inc., a massive breach that the company concealed for more than a year. This week, the ride-hailing company ousted Joe Sullivan, chief security officer, and one of his deputies for their roles in keeping the hack under wraps. Compromised data from the October 2016 attack included names, email addresses and phone numbers of 50 million Uber riders around the world, the company told Bloomberg on Tuesday. The personal information of about 7 million drivers were accessed as well, including some 600,000 U.S. driver’s license numbers. No Social Security numbers, trip location details or other data were taken, Uber said.
