A phone-based attack, also known as a SIM-swap or phone-port attack, involves an attacker gaining control of their target's phone number by transferring it to a mobile device under their control. This can be achieved through identity theft or social engineering mobile carrier Customer Support representatives. Any account using SMS-based 2-step verification or that can be recovered using phone-based authentication is vulnerable to this type of attack.
To prevent a phone-based attack on your Wirex account, it is highly recommended that you use a stronger form of 2-step verification. This can include 2FA with a security key or time-based One Time Password with a mobile authenticator app like Duo or Google Authenticator. These methods provide an added layer of security and can help protect your account from unauthorised access. For more information on keeping your Wirex account secure, please visit our website.
