T-Mobile is reportedly adding PIN protection to its port-out process

T-Mobile is adding another layer of security to its port-out process with the addition of a six-digit PIN, T-Mobile said. The T-Mo Report† Under the new number porting procedure, users would reportedly be required to obtain a PIN from T-Mobile’s app or site and provide it when attempting to change their number to another carrier, which could make it more difficult for attackers to access the numbers. steal from people.

According to The T-Mo ReportT-Mobile announced the process internally, but has not yet rolled it out to customers. It will also reportedly only be available to postpaid customers to begin with, with the exception of people who have signed up through the Lifeline program.

T-Mobile did not immediately respond to The edge‘s request to confirm these plans. The T-Mo Report quoted an internal company document it said it obtained.

It’s good to hear that T-Mobile may be adding this feature as it could help prevent SIM-swapping attacks where a scammer convinces a telecommunications provider to hand over a phone number under their control. Such as android police notes, Verizon and AT&T have already implemented porting PINs. While it may not prevent all SIM-swapping attacks (in theory, an attacker with a T-Mobile account and device wouldn’t have to go through the port-out process because the number would remain in the same network), the PIN requirement can act as another line of defense alongside T-Mobile’s existing account takeover protection tools.

Sim-swap, or porting-out, attacks seem to have become popular with cybercriminals in recent years and have been involved in high-profile cases, such as when then-Twitter CEO Jack Dorsey’s Twitter account was hacked. They’re attractive for a few reasons: they provide a wealth of information (many two-factor codes are still sent via text message), and it can be difficult for a victim to realize they’ve been attacked and recover from it. The Federal Communications Commission recommends contacting your wireless carrier immediately if you suspect that someone has switched your SIM card, but that can be difficult because your phone is no longer functional.

T-Mobile’s reputation for security has taken a few knocks of late as the company has been hit by a series of data breaches and cybersecurity incidents. While some were relatively small, one affected more than 50 million people in August 2021.
