Uber was hacked last year (its board and new CEO just found out).
Late Tuesday, in an announcement its CEO posted to the company's website, Uber disclosed that it had sustained a breach in October 2016 (Uber). It's just now making the data loss public (Bloomberg). The breach isn't record-setting, but it's big enough: Uber says that 57 million individuals (mostly users, but including some 600 thousand drivers) were affected. Riders' names, email addresses and mobile phone numbers were lost; drivers' names and license numbers were exposed. User information was lost in many countries around the world, but the affected drivers appear to have all worked in the US. Users may get more information from Uber here, and drivers may go to this site for help. (The company says that the following information was not affected: "trip location history, credit card numbers, bank account numbers, Social Security numbers or dates of birth.")
