T-Mobile customers’ address, number, and other info allegedly up for sale; company denies claim
Cybernewsreports that hackers stole the data of 64 million customers. They allegedly managed to get their hands on highly sensitive details, such as full name, date of birth, Tax ID, house address, email address, IP address, and phone number.
T-MobiletoldThe Mobile Report that it has examined the data sample posted by hackers online and has determined that the information is not related to the company or its customers.
Any reports of a T-Mobile data breach are inaccurate. We have reviewed the sample data provided and can confirm the data does not relate to T-Mobile or our customers.

The sample data was posted on a forum that’s the go-to marketplace for sellers attempting to sell such information. The poster is someone who has shared legitimate data in the past.
Given that T-Mobile says that it reviewed the data and found no links to itself, customers don’t necessarily need to worry. However, the fact that the information appears to be legitimate and fresh leaves room for concern.
T-Mobile settlement checks for the 2021 data breach only recently started going out and another breach on the heels of that would reflect poorly on the company and its claim that it dedicated resources to improving system defenses.
