T-Mobile data breach overview: 

  • Who: T-Mobile disclosed in a letter to customers late last month that it suffered a data breach, the second such incident of the year. 
  • Why: The breach exposed the private information of more than 800 T-Mobile customers and included names, birthdates, addresses, Social Security numbers, contact information, government IDs and T-Mobile account PINs. 
  • Where: The T-Mobile data breach affects consumers nationwide.
  • What are my options: Consumers wishing to better protect their own data may be interested in Norton LifeLock.

A T-Mobile data breach affected more than 800 of its customers, marking the second time this year a data breach has hit the mobile telecommunication company.

The latest breach happened between February and March, according to the company, which revealed hackers had accessed private data such as names, birthdates and Social Security numbers, The Verge reports

The data breach also reportedly exposed T-Mobile account holders’ addresses, contact information, government IDs and T-Mobile account pins. 

In a letter sent to customers April 28 and shared by BleepingComputer, T-Mobile did not reveal how the breach occurred but said it “has a number of safeguards in place to prevent unauthorized access such as this” and apologized for the incident. 

“We take these issues seriously. We apologize that this happened and are furthering efforts to enhance security of your information,” T-Mobile says in its letter to customers. 

T-Mobile claims none of its customers’ personal financial information or call records were compromised in the breach and said the information affected varied from customer to customer. 

T-Mobile says it ‘proactively reset’ affected customers’ T-Mobile account PINs

T-Mobile has informed its customers it had “proactively reset” their T-Mobile account PINs, and is offering two years of free credit monitoring and identity theft detection services through myTrueIdentity, from Transunion. 

The data breach is the ninth the company has suffered since 2018, and the second already this year, The Verge reports.

T-Mobile disclosed in a filing with the U.S. Securities and Exchange Commission earlier this year that a data breach between November 2022 and January 2023 exposed the private data of around 37 million of its customers. 

The company revealed it discovered the data breach Jan. 5 and believed the incident began on or around Nov. 25, 2022.

    We have T-Mobile I-Phones; And every Customer should have received notification that even the additional lines; 2nd & 3rd lines; just in case, instead of them reporting only 800 Customers; how can U just report a certain #? This affects every Customer; WE keep getting all types of calls & texts we have opt out daily! Legally notified “EVERY CUSTOMER” not just 800! T-mobile doesn’t want face Liability!
