On Thursday, T-Mobile has announced a security breach that affected some of its prepaid customers in the United States.
The company told it Squeaky computer on Thursday that a "small number of customers" was affected by the infringement discovered earlier this month. According to T-Mobile, customer names, addresses, telephone numbers, account numbers, tariff plans and plan functions remained visible. More sensitive information such as passwords, financial information or social security numbers were not affected.
T-Mobile told affected customers this week that its cyber security team has discovered and closed "malicious, unauthorized access" to their accounts. Shortly thereafter, the telecommunications company informed the law enforcement of the infringement.
If your data has been breached, T-Mobile should have sent an SMS today to notify you, but if you have changed your provider or number, you may not have received it. You can contact T-Mobile at email@example.com or by calling 611 to check if your account has been affected.
"We really regret this incident and we apologize for any inconvenience." T-Mobile said in a statement.
In August 2018, T-Mobile was again hit by a data breach and the account information of nearly 2 million customers was stolen by hackers. Account data such as telephone numbers and e-mail addresses have been violated, but no sensitive information such as social security numbers has been compromised.
