SAN FRANCISCO — Personal information of millions of Uber customers and drivers were stolen by hackers in 2016, in a breach that the company has kept secret for more than a year. <br /> <br />Bloomberg reports that In October 2016, two hackers gained access to a third-party cloud-based service used by Uber, and obtained information on 57 million of its users. <br /> <br />Compromised data from the attack included names, email addresses, phone numbers, as well as license numbers of around 600,000 U.S. drivers. <br /> <br />The company claims users' bank and credit card information, social security numbers, trip location history and dates of birth were not accessed. <br /> <br />The hackers reportedly emailed Uber asking for money, and were paid $100,000 to delete the stolen files and keep quiet about the breach. <br /> <br />News of the hack was not disclosed to either its users or any government agencies, despite a number of state and federal laws requiring the company to do so. <br /> <br />Uber's chief security officer and a senior lawyer have been sacked for their shady handling of the hack. The New York State Attorney General has also opened an investigation into the incident, according to USA Today.
