T-Mobile assesses aftermath of 2021 cybersecurity attack

T-Mobile is the recent victim of a cybersecurity attack. 

The Un-Carrier quickly responded to reports that a hacker was able to access the customer information of nearly 100 million customers. And while the hacker’s entry point has been closed, T-Mobile’s investigation continues to show disappointing numbers. 

Earlier today, T-Mobile revealed that they discovered more customers that were victimized in the attack. The numbers added today are different from the 48 million that they announced yesterday. In a nutshell, these are the numbers:

• 40 million former or prospective T-Mobile customers

• 13.1 existing T-Mobile postpaid customers

• 1.5 existing T-Mobile Prepaid customers

• 52,000 Metro by T-Mobile customers

T-Mobile says that the customers had their customer names, birthdays, addresses, phone numbers, IMEIs, and IMSIs stolen in the hack. Yesterday’s victims had their SSNs and Driver’s License/ID information stolen from them too. 

At this point, former Sprint prepaid and Boost Mobile customers remain to be free from the attack. 

The Federal Communications Commission (FCC) has started its own investigation and has filed at least one class-action lawsuit against T-Mobile. The agency also said that T-Mo’s two-year identity protection service offer is “inadequate”.
