Experian and T-Mobile Data Breach Investigation

Goldman Scarlato & Penny, P.C. is investigating a possible claim on behalf of persons whose private information was compromised as a result of a data breach announced by credit reporting agency Experian on October 1, 2015.  The breach compromised the records of about 15 million people.  According to Experian, the breach occurred on a server that contained customer data for one of Experian’s clients, T-Mobile.

Anyone who applied for T-Mobile cell phone services between September 1, 2013 and September 16, 2015 is at risk for having their personal information compromised.  Experian was hired by T-Mobile to process new account applications and to make credit decisions about the new applicants.


The stolen data includes names, birthdates, addresses, social security numbers, and an “identification number” (described by Experian as typically a driver’s license, military ID, or passport number) and “additional information used in T-Mobile’s own credit assessment.”   Experian claims that credit card or payment information was not exposed.


Notices will go out to those affected by the T-mobile data breach in the near future, according to a T-Mobile spokesperson.  T-Mobile is offering two years of credit monitoring and identity protection services.


According to a T-Mobile representative, the T-Mobile data breach breach was discovered by Experian on September 15, 2015.


The T-mobile data breach is just the latest in a string of data breaches involving companies that maintain sensitive personal information of consumers. For example, in February 2015, Anthem Inc., the second largest health insurer in the country, announced a data breach that exposed the personally identifiable information (commonly referred to as “PII”) of almost 80 million of its customers and employees. Then in March 2015, Premera Blue Cross announced a data breach that exposed the PII of 11 million customers and employees.


Unfortunately, how the stolen data might impact T-Mobile’s current and former customers will take some time to be revealed. As we saw with the Anthem and Premera data breaches which also involve the theft of social security numbers, repercussions can be frightening. Coinciding with those two breaches were an alarming number of reports of stolen social security numbers being used to file false tax returns and claim refunds in the names of the persons whose identity was stolen. Potential fraudulent activity could also include obtaining credit in the identity theft victim’s name.
