AT&T has introduced a new Account Lock feature to safeguard wireless users from SIM swapping attacks. This feature, accessible through the myAT&T app, prevents unauthorized changes to user accounts, including phone number transfers, SIM changes, and billing updates. SIM swapping attacks, which have increased in frequency, occur when an attacker gains access to a victim's phone number, allowing them to intercept sensitive communications. Similar features are offered by other carriers like T-Mobile and Verizon. Users can manage the Account Lock through the app and receive notifications of any changes made.
AT&T's new Account Lock feature protects wireless users against unauthorized account changes, including phone number transfers and SIM card changes, significantly reducing the risk of SIM swapping attacks.
The Account Lock feature can be enabled from the myAT&T app and protects against unauthorized changes like device upgrades and updates to billing information.
SIM swapping attacks have surged, where attackers impersonate victims to gain control of their phone numbers, intercepting sensitive messages and two-factor authentication codes.
Other carriers such as T-Mobile, Verizon, and Google Fi currently offer similar features aimed at preventing fraud and protecting user accounts.
