How a SIM-swap scam cost one man $38K overnight—and how you can protect yourself
- Replies 0
In today’s world, where so much of our personal and financial life is managed through our mobile devices, the security of our digital identity has never been more important. But what happens when that security is compromised?
Justin Chan, from Carlsbad, California, found out the hard way, falling victim to a SIM-swapping scam that drained a staggering $38,000 from his Bank of America account. How did this happen—and more importantly, how can you protect yourself from such a sophisticated threat?
SIM-swapping is a form of identity theft that allows scammers to hijack your phone number. By convincing your mobile carrier to transfer your number to a SIM card they control, they can intercept your calls and text messages—including those containing two-factor authentication (2FA) codes.
That’s exactly what happened to Chan. One evening, he noticed his iPhone had been disconnected from the network, only to discover later that his bank account had been drained.
The scammer had called Xfinity Mobile, pretending to be Chan, and with just the last four digits of his credit card, they managed to transfer his number to a new SIM card. This gave the fraudster access to Chan’s bank account, allowing them to wire $38,000 to a Wells Fargo account in the middle of the night.
Unfortunately, this is a common problem for many victims of SIM-swapping. Both banks and mobile carriers often struggle to differentiate between legitimate transactions and those authorized by scammers.
While the FBI has reported around 800 SIM-swapping cases nationwide this year, the actual number is likely much higher due to underreporting.
Last year alone, SIM-swapping scams cost victims more than $48 million. Law enforcement may sometimes be able to freeze the stolen funds, but the chances of recovery decrease as time goes by.
1. Set Up a PIN with Your Mobile Carrier: Contact your carrier and request a unique PIN or passcode for any changes to your account. This will add an extra layer of security.
2. Use Unique Passwords: Ensure all your online accounts have strong, unique passwords. A password manager can help you keep track of them securely.
3. Enable Multi-Factor Authentication: Use multi-factor authentication (MFA) that doesn’t rely on text messages. Authentication apps or hardware tokens are safer options.
4. Stay Informed: Keep up with the latest security protocols recommended by your bank and mobile carrier to stay ahead of potential threats.
5. Be Skeptical: Always verify the source independently if you receive unexpected requests for personal information or account changes.
6. Report Incidents: If you suspect you’ve fallen victim to SIM-swapping, report it immediately to your mobile carrier, bank, and the Internet Crimes Complaints Center.

The Aftermath: A Battle for Justice
Chan’s ordeal didn’t end with the theft.
