Uber concealed hack affecting 57 million people
Uber concealed a data breach that affected 57 million customers and drivers. The ride-sharing firm hid the breach in 2016 by paying hackers $100,000 (£75,000) to delete the data.
The hackers stole 57 million names, email addresses and mobile phone numbers, including the names and license plate details of 600,000 drivers. According to Bloomberg, Uber’s former chief executive Travis Kalanick knew about the breach over a year ago.
