T-Mobile Data Breach Overview:

  • Who: A hacker gained access to T-Mobile’s servers, potentially stealing data of 100 million T-Mobile customers.
  • Why: The customers’ personal information is now being sold on online forums.
  • Where: T-Mobile is headquartered in Washington, but the data breach may affect millions of customers across the United States.

Hackers have potentially nabbed the personal information of 100 million T-Mobile USA customers, which is reportedly being sold on online forums. 

The data breach includes customers’ names, Social Security numbers, addresses, dates of birth, phone numbers, and unique device identification numbers, according to Krebs on Security. The data, which does not include Sprint accounts, may even go as far back as the mid-1990s.

An ongoing investigation by T-Mobile confirmed the data breach, but not whether personal customer data was leaked or the scale of the breach. 

In a statement, T-Mobile noted that it was “confident that the entry point used to gain access has been closed.” 

However, Motherboard reports that it obtained intel from the person selling the stolen information online, who claims the hacker already “backed up [the customer data] in multiple places” before T-Mobile restricted access. 

A class action lawsuit has not yet been filed for this T-Mobile data breach. In 2015, T-Mobile and Experian North America Inc. faced a class action lawsuit by consumers who claimed their information was exposed in a data breach that potentially affected 15 million people.

Who Caused The T-Mobile Data Breach?

The identity of the hacker has not yet been revealed or confirmed by T-Mobile or other authorities.

As Krebs on Security reports, the Twitter account @Und0xxed called attention to the breach on the social media platform. 

Although claiming to not be the hacker themselves, they have given credit to the Twitter user @IntelSecrets, who may also be known under the names IRDev and V0rtex. 

Top Class Actions will continue to monitor the T-Mobile data breach and report on any updates.
