Yes, Uber users should be worried. While Uber has never had a major data hack, there have been a number of smaller data breaches in the past. In 2014, Uber was hacked and the personal information of 50 million users was stolen. In 2016, Uber was hacked again and the personal information of 600,000 drivers was stolen. And in 2017, Uber was hacked a third time and the personal information of 3 million users was stolen.

Overall, Uber has had a poor track record of protecting user data. Users should be concerned that their personal information could be stolen in a future hack.

Here are some tips to protect your personal information when using Uber:

- Use a strong password and don't reuse passwords across multiple accounts.

- Enable two-factor authentication on your Uber account.

- Be careful what information you share with Uber. Don't share your social security number or credit card number with Uber unless you're absolutely certain it's necessary.

- Regularly review your Uber account activity and look for any suspicious activity.

- If you think your Uber account has been hacked, change your password immediately and contact Uber customer support.
