Today, T-Mobile customers said they could see other peoples' account and billing information after logging into the company's official mobile application.
According to user reports on social media, the exposed information included customers' names, phone numbers, addresses, account balances, and credit card details like the expiration dates and the last four digits.
As first reported by The Verge, some of the customers affected by this issue could see the sensitive information of multiple other people while logged into their own accounts.
In January, the mobile carrier revealed another data breach after the sensitive info of 37 million customers was stolen using one of its Application Programming Interfaces.
In 2019, T-Mobile exposed the account info of an undisclosed number of prepaid customers.
In February 2021, an internal T-Mobile app was accessed by unknown attackers without authorization.
