T-Mobile has disclosed a security incident that customer phone numbers and certain account information were breached.
The mobile company confirmed the data breach “did not include names on the account, physical or email addresses, financial data, credit card information, social security numbers, tax ID, passwords, or PINs.“
T-Mobile’s Cybersecurity term recently discovered the incident and then shut down malicious, unauthorized access to certain information related to T-Mobile accounts.
“Customer proprietary network information (CPNI) as defined by the Federal Communications Commission (FCC) rules was accessed. The CPNI accessed may have included phone number, number of lines subscribed to on your account and, in some cases, call-related information collected as part of the normal operation of your wireless service,” Matt Staneff of T-Mobile USA stated in the customer notice posted online.
According to BleepingComputer, the incident likely impacted up to 200,000 customers out of 100 million customers.
In addition, T-Mobile customers can also contact their customer service team at 1-800-937-8997 or review the company’s Privacy Resources at https://www.t-mobile.com/responsibility/privacy.
Readers may remember when T-Mobile experienced a data breach in November 2019 that exposed prepaid customer names, billing addresses, phone numbers, account numbers and Rate plan information. In that incident, the company also confirmed that no SSN or payment card information was stolen.
