The news just came out that Uber suffered breach a year ago, and the address and email information of 57 million people were stolen. Uber paid off the hackers who then supposedly deleted the data, but that cannot be confirmed.
Finally, this week, they fired their chief security officer and one of his deputies for their roles in keeping the hack under wraps, which included a $100,000 payment to the attackers to "delete the data".
Uber says it has "not seen evidence of fraud or misuse tied to the incident." No one knows for sure, but it is highly unlikely that these records were deleted. It's very likely they are sold on the dark web or will be. There are many ways that data could be abused by criminals without Uber ever becoming aware.
Watch out for phishing emails related to this Uber data theft, for instance that your "Uber account was compromised" and that you need to change your password, or anything else related to Uber that could be suspicious.
