T-Mobile Reports Second Data Breach since the Beginning of the Year
T-Mobile warned of a second data breach in 2023 – this time, the attackers gained access to the personal information of hundreds of customers and retained access to data for more than a month (starting from the end of February 2023).You might also be interested to know that Attackers have been monitoring SIM card owners for more than two years with a Simjacker attack.
Compared to previous T-Mobile data breaches, the latest of which affected 37 million people, the new incident affected “only” 836 customers. However, the volume of information disclosed is large and the leak puts users at risk of identity theft and phishing attacks.
In notifications sent to victims, the company says that from February to March 2023, attackers “gained access to limited information for a small number of T-Mobile accounts.”
T-Mobile emphasizes that the attackers did not have access to call records or information about the financial accounts of the affected individuals.
However, the “leaked” information varied from user to user and could include: full name, contact information, account number and associated phone numbers, T-Mobile account PIN, social security number, identification document details, date of birth, amount payable, the internal codes that T-Mobile uses to service your accounts (such as your billing plan and feature codes), and information about the number of available lines.
After discovering the hack, T-Mobile reset the PINs for the accounts of all those affected. Victims of this incident are now being offered two years of free credit monitoring and identity theft detection services.
