T-Mobile Discovers That Their Pwnage Issues Are Worse Than They Thought

This morning, T-Mobile has shared its latest discoveries as it continues its investigation into the hack that resulted in information on almost 50 million people has been leaked. The new information indicates that 5.3 million more current postpaid customer accounts that were compromised:

We previously reported information from approximately 7.8 million current T-Mobile postpaid customer accounts that included first and last names, date of birth, SSN, and driver’s license/ID information was compromised. We have now also determined that phone numbers, as well as IMEI and IMSI information, the typical identifier numbers associated with a mobile phone, were also compromised. Additionally, we have since identified another 5.3 million current postpaid customer accounts that had one or more associated customer names, addresses, date of births, phone numbers, IMEIs and IMSIs illegally accessed. These additional accounts did not have any SSNs or driver’s license/ID information compromised.

And that’s not all:

We also previously reported that data files with information from about 40 million former or prospective T-Mobile customers, including first and last names, date of birth, SSN, and driver’s license/ID information, were compromised. We have since identified an additional 667,000 accounts of former T- Mobile customers that were accessed with customer names, phone numbers, addresses and dates of birth compromised. These additional accounts did not have any SSNs or driver’s license/ID information compromised.

I have the sneaking suspicion that more details are going to leak out that will bring this number to the 100 million that was previously reported. And that won’t be a good look for T-Mobile.

  2. […] it comes to the fact that they were either victims of massive pwnage, or just badly pwned, and it may still get worse for them. Especially since the hacker that pwned them says that their security was […]
