AT&T has launched a new security feature called Wireless Account Lock to protect its customers from SIM swapping attacks and account takeovers. This feature allows users to lock down their accounts, preventing unauthorized access by threat actors attempting to hijack phone numbers for fraudulent purposes. The rollout follows similar protections introduced by other major carriers such as T-Mobile, Verizon, and Google Fi. The Wireless Account Lock aims to enhance customer security by blocking attempts to access sensitive information through SIM swap scams, which have been increasing and are often exploited in crypto-related crimes. The feature is designed to be simple to use and widely available to AT&T wireless users.
