While T-Mobile confirmed a recent system detection that revealed a threat actor had accessed a small number of accounts, which compromised limited information.

836 customers were affected by the intrusion, which commenced on February 24 and continued till March 30.

What Happened?

T-Mobile’s security measures worked as intended in March 2023, alerting them to unauthorized activity.

During late February through March 2023, a threat actor gained access to restricted data from a few T-Mobile accounts, as revealed by their security system.

This year’s second T-Mobile hack is the ninth security breach since 2018, and in January, the misuse of T-Mobile’s application programming enabled threat actors to access 37 million customers’ data.

What Is T-Mobile Doing?

Despite having several safeguards to prevent unauthorized access, T-Mobile acknowledges the need to enhance its security measures continually. 

They take such incidents seriously, apologize for the breach, and are working towards improving the security of customers’ information.

T-Mobile reset their customers’ T-Mobile Account PIN to safeguard their accounts. Additionally, they provide free identity theft detection services and credit monitoring for two years through Transunion’s myTrueIdentity.

Moreover, T-Mobile conducts a thorough investigation to understand unauthorized activity and improve its safeguards to prevent such incidents from happening again.
