SIM-Swap (Subscriber Identity Module) is a type of attack on mobile devices that can be used to gain access to an individual’s personal information. It occurs when a hacker contacts a victim’s wireless carrier and requests that the SIM card linked to their phone number be transferred from one device to another. This allows the attacker full control over the victim’s communications, including text messages, voice calls, and data usage as well as access to any accounts or services associated with those channels.
Once this has been accomplished, attackers can reset passwords for financial accounts or other sensitive services by intercepting security codes sent via SMS or automated call request. They may also use this method of attack in order to steal cryptocurrency stored on wallets accessible through the device they have taken over.
In order to protect yourself from SIM-Swap attacks it is important that you keep your wireless carrier informed of your current contact details so they are aware if someone attempts such an attack in your name. Additionally it can help limit exposure if you disable two factor authentication (2FA) via SMS – instead relying on 2FA through an authenticator app or hardware token where possible. Finally ensure that any crypto wallet apps installed on your phone are adequately secured using strong passwords and biometric authentication methods such as faceID/fingerprint recognition where available
