Regulators around the world are probing a massive data breach at ride-hailing service Uber and its apparent role in covering it up.
On Tuesday, Uber disclosed that hackers stole data from 57 million riders and drivers in an attack that happened in 2016. The company paid the hackers $100,000 to delete the data and keep the breach quiet.
Uber fired Chief Security Officer Joe Sullivan for his role and CEO Dara Khosrowshahi, who was not with the company at the time of the hack, said "none of this should have happened."
But the U.S. technology firm is now in the cross-hairs of regulators around the world.
Australia's data protection watchdog said it has "commenced inquiries with Uber."
"Incidents such as this are a timely reminder to Australians of the value of the personal information we provide in order to receive products and services," the Australian Information and Privacy Commissioner's office, said in a statement on Wednesday.
Singapore's Personal Data Protection Commission told CNBC in an emailed statement on Thursday that it is "aware of the breach and is in touch with Uber for more details."
The U.K.'s Information Commissioner's Office (ICO) told CNBC on Wednesday that Uber could face an investigation and even potential fines up to £500,000 ($661,900).
"We will be investigating but as regards what actions we eventually take, that depends on what we find, and obviously it's very early days at this stage," an ICO spokesperson told CNBC by phone on Wednesday.
An Uber spokesperson told CNBC on Thursday that it's in the process of notifying various regulatory and government authorities and expects to have "ongoing discussions" with them.
"Until we complete that process we aren't in a position to get into any more details."
At home in the U.S., five states said they would investigate the data breach, according to a Recode report on Wednesday.
