AT&T has introduced a new feature to protect consumer and business accounts from SIM-swapping attacks. Wireless Account Lock will be able to disable several key account changes, a key part of SIM-swapping, which can give attackers control of a victim’s phone number and lets them intercept SMS-based two-factor authentication app codes.

If you're an AT&T customer, you can turn on a new security feature that prevents your phone number from being moved to a different device without your knowledge, exposing your data to cyber criminals in the process.

AT&T has a nifty new way of ensuring that its customers don't get SIM swapped.
