T-Mobile Data Breach

On August 17th, 2021, T-Mobile learned that a bad actor illegally accessed personal data. The company was investigating a leak after someone was offering to sell personal information of cellphone users on a forum. They confirmed that there was unauthorized access to some T-Mobile data and that it had closed the entry point used to gain access.


Over 40 million people who applied for T-Mobile credit were exposed. The exact personal information accessed, varies by individual. The stolen data includes: names, drivers’ licenses, government identification numbers, Social Security numbers, dates of birth, and T-Mobile account PINs.


Gartner analyst Paul Furtado said, "T-Mobile has been hit before by data theft but in the most recent case, the sheer numbers far exceed the previous breaches."


In response, T-Mobile said, "Customers trust us with their private information and we safeguard it with the utmost concern. A recent cybersecurity incident put some of that data in harm’s way, and we apologize for that. We take this very seriously, and we strive for transparency in the status of our investigation and what we’re doing to help protect you."


Based in Bellevue, Washington, T-Mobile became one of the country's largest cellphone service carriers, along with AT&T and Verizon, after buying rival Sprint. The company will offer two years of free identity protection services and is recommending that all of its postpaid customers change their PIN.


Forrester analyst Allie Mellen said, “It’s a real indictment on T-Mobile and whether or not these customers would want to continue working with T-Mobile.” She added that the hack didn’t appear particularly sophisticated.


The last data breach was in January and before that in November 2019 and August 2018.
