Uber’s ex-security chief faces landmark trial over data breach that hit 57m users

Joe Sullivan's trial is believed to be the first case of an executive facing criminal charges over such a breach

Uber's former security officer, Joe Sullivan, is standing trial this week in what is believed to be the first case of an executive facing criminal charges in relation to a data breach.

The US district court in San Francisco will start hearing arguments on whether Sullivan, the former head of security at the ride-share giant, failed to properly disclose a 2016 data breach affecting 57 million Uber riders and drivers around the world.
