San Antonio Uber drivers want an explanation after the personal information of about 57 million Uber users was stolen by hackers more than a year ago.

According to reports, the stolen data included names, email addresses, and phone numbers of 50 million Uber riders and 7 million drivers.

Bloomberg reported Uber was legally obliged to report the breach to authorities but instead paid hackers $100,000 to delete the data and keep it quiet. That move got the company's chief security officer fired.

This is prompting Uber drivers here in San Antonio to question their future with the company.

"The fact they were trying to hide it... I mean, I don't know what to say about that... and for an entire year," said Joey, who's been driving for the company for several months. "They owe the public an apology to its drivers and it's customers, just be forward about it,"

Another driver, Kori Flores, says some of her customers have already asked her about the breach during their rides.

"It's kind of scary, they have our Social security numbers, our ID's, anybody can get into our bank accounts," said Flores.

But, in a statement, the company's CEO said they don't have evidence that credit card numbers, bank account numbers, or Social Security numbers were downloaded.

Although, the company says they are monitoring the affected accounts and have flagged them for fraud protection. They are also notifying the drivers whose driver's license numbers were downloaded.
