SIM Swapping: How Criminals Hijack Your Phone Number
What is this scam?
SIM swapping is a sophisticated scam where fraudsters hijack someone's mobile phone number by taking control of their SIM card. They achieve this by convincing the victimβs telecom provider that they are the legitimate owner. Once in possession of the phone number, scammers can access bank accounts, steal identities, and conduct fraudulent transactions. According to the Federal Trade Commission (FTC), SIM swapping scams have been reported in increasing numbers, with over 30% of victims experiencing financial loss. The Better Business Bureau (BBB) has also noted a significant rise in complaints, highlighting the need for heightened vigilance among consumers.
How the scam works
Real examples
Alice noticed her phone was not receiving any messages but received a notification on an app about a password reset. She called her carrier and learned someone had requested a SIM swap using stolen personal information.
Bob got a call from his bank asking to verify recent transactions he didn't make. Upon investigation, it turned out that scammers used SIM swapping to access his banking account through text-based two-factor authentication.
