On late Thursday, T-Mobile revealed that hackers stole some of the personal data of 2 million people in a new data breach.

In a brief intrusion, hackers stole "some" customer data including names, email addresses, account numbers, and other billing information. The good news is that they did not get credit card numbers, social security numbers, or passwords, according to the company.
