Uber has just revealed that a data breach within the company occurred after a group of hackers accessed the personal data of more than 57 million accounts, as well as the names and driver's licence numbers of more than 600,000 drivers in the US. The incident took place since October 2016 which may have worried millions of riders around the world.

The stolen information included the names, mobile phone numbers and email addresses registered on the ride-sharing service's app. Uber's external forensics experts believe that there has not been "any indication that trip location history, credit card numbers, bank account numbers, Social Security numbers or dates of birth were downloaded."
