According to internal documents T-Mobile provided to T-MO Report, this attack is described as “performing unauthorized behavior on customer accounts” and “affects only a small part of the customer’s account.” small customers”.
Unauthorized acts revealed by the document are viewing customer proprietary information (CPNI) and SIM swapping, specifically:
- CPNI information: payment account name, phone number, T-Mobile account number, tariff plan…
- Unauthorized SIM swapping: change the SIM card associated with a phone number to gain control over that phone number. From here, the hacker can gain access to the victim’s other online accounts through a two-factor authentication code sent to their phone number.
In addition, it seems that when this document was leaked to T-MO Report, T-Mobile took the initiative to send an email to apologize and fix the consequences.
Not long after this document was leaked, T-Mobile was accused of hiding the incident on Twitter. The tweet was responded to by the official T-Mobile support page (@TMobileHelp) confirming the issue.
