T-Mobile Data Breach: What You Need To Know

A highly publicized data security breach on T-Mobile was announced last week and Millions of users’ data might have been exposed.

T-Mobile confirms that there are encrypted passwords involved in the security breach. Their cyber-security team uncovered and eventually prevented further unauthorized access to their systems and immediately reported it to the authorities. This means that someone somewhere might have all those users’ personal information.

Regardless of the users’ account type – prepaid or postpaid – data was confirmed breached and possibly exposed. There are also several reports that the issue was due to a vulnerable API, or application programming interface, although it still remains uncertain. So, to breakdown the event based on facts, here’s what you need to know:
