Access to T-Mobile customer information

T-Mobile, the phone operator, reported its second data breach in 2023 (ninth since 2018), after discovering that a group of attackers gained access to the personal information of hundreds of customers between February and March 2023.

The filtered data includes full name, contact information, account number and associated phone numbers, account PIN, date of birth, and internal codes used by the company, among other data.

T-Mobile has reset the PIN codes of affected accounts and recommends that customers review and improve their account security settings.
