Did you take an Uber taxi ride last year? If so, you might well have had your private details hacked and made available to the world.

The alternative taxi service has informed the Australian Privacy Commissioner that it believes the details of some 1.2 million Aussie riders were affected when hackers breached its systems internationally in late 2016.

As it turned out , the global breach was covered up by the company for more than a year, before a media exposé in the USA saw it concede that the names, e-mails and mobile numbers of some 57 million users worldwide had been breached. Details of Uber drivers were also broadcast by the attackers.

In the USA, Uber late last week admitted it had paid hackers US$100,000 to delete the data, but has no positive conformation this was ever done. 

Three senior managers have now resigned from Uber’s international business operations and physical security teams, amid the fresh wave of scrutiny over the company’s data security and competitive practices.
