Experian today announced that one of its business units experienced a serious data breach, with hackers acquiring personal information for approximately 15 million T-Mobile users, as T-Mobile was the Experian client that was affected by the hack.

While credit card information was not obtained, data acquired from T-Mobile includes names, dates of birth, addresses, and Social Security numbers. In some cases, ID like a drivers' license or passport number was acquired, in addition to other information T-Mobile uses for credit assessments.

Consumers who applied for T-Mobile postpaid services between September 1, 2013 and September 16, 2015 were affected. Experian is notifying T-Mobile customers whose data was obtained and offering them two years of credit monitoring and identity protection through ProtectMyID.

T-Mobile CEO John Legere has penned a letter to customers about the breach and on Twitter, Legere says T-Mobile is looking into alternate service protection options that will be implemented shortly.

Obviously I am incredibly angry about this data breach and we will institute a thorough review of our relationship with Experian, but right now my top concern and first focus is assisting any and all consumers affected. I take our customer and prospective customer privacy VERY seriously. This is no small issue for us. I do want to assure our customers that neither T-Mobile's systems nor network were part of this intrusion and this did not involve any payment card numbers or bank account information.

According to Experian, steps have been taken to prevent additional attacks, and there has been no evidence thus far that the data "has been used inappropriately."

if people in shithhole countries keep hacking into western databases like this, they should not be allowed to have internet.

UGH!!! I switched to T-Mobile days before the affected period with my whole family. DAMMIT!!! This is total BS!!! Sorry, I am just super angry right now. Just when I was happy about saving over $100 a month by leaving Verizon.
I don't blame T-Mobile for this this. I do blame Experian for this. These guys are responsible for managing the personal information of 10s of millions of people (if not more). It better not be the case that their security is lame (i.e. the hackers better be hot s**t) because if it is lame, then there needs to be some serious legal action taken against them. Even criminal action taken against their executives.

In other words the data has been used appropriately by hackers! Are you kidding me!

Experian better be providing credit monitoring for every single T-Mobile customer who's credit they pulled. This is unacceptable. Companies like experian that hold all the information needed to steal my identity should have safeguards in place to ensure they can not give that information away and if some data is taken its not possible to take all the parts necessary to ruin someone's credit.

Experian "Yes we messed up. But we will only monitor your credit for 2 years." Because that is how much we value your identity....

Experian, is a piece of **** company. In the credit business, and unprotecting data. So glad in a wink of an eye, you have now "fixed the problem".

So sure you are continuing to sell consumer data to third party marketers, and those mass mail trigger leads. Your company should be fined a 4k per person you put in harms way, just like the CFPB fines banks for similar abuse.

The Fair Credit Reporting act needs to be re-vamped and the Big three need a beat down. TU and Equifax are no better.
