What is SIM swapping & how does the hijacking scam work?
SIM swapping, also known as SIM splitting, simjacking, or SIM hijacking, is a technique used by fraudsters to get control of your phone number. With your phone number, hackers can take advantage of two-factor authentication to gain access to your bank accounts, social media accounts, and more.
To understand SIM swapping, you first have to know how two-factor authentication and SIM cards work.
Security experts recommend two-factor authentication to protect your online accounts, but it isn’t a perfect system – a third party with your phone number could bypass it. Two-factor authentication alone doesn’t 100% protect your accounts from getting hacked.
Setting up two-factor authentication for an account typically entails providing your cell phone number, so that you can receive unique codes to use each time you log in after entering your username and password. The code may also be sent to your email. Since two-factor authentication has become so common, hackers now have another challenge to gaining access to your information – they now need to get your cell phone number, too.
