Don't Call Back: The Simple Missed Call Scam Costing Americans Millions

Everyone has witnessed it: a single ring from an unidentified number followed by silence. In the United States, a missed call from a stranger is frequently the result of a robocall testing a line or an incorrect number. However, a risky development of this strategy is making curiosity an expensive error. Although a missed call by itself cannot deplete your bank account, returning the call creates a vulnerability that con artists are quick to take advantage of.

This fraud takes advantage of our natural curiosity and anxiety. After one ring, a call from an unknown number—often spoofing it to appear local or somewhat familiar—hangs up. The objective is to get you to call back, not to speak with you at first. One of several complex scam schemes intended to steal your identity or money is activated by that returned call.

The "One-Ring" Scam's Development

Step 1: The Bait

• An unknown number leaves you a missed call. It's intended to arouse interest or worry—"Who was that? Was it significant?

Step 2: The Trap Springs

• When you return the call, you can connect to:

• A Premium-Rate Number: You may hear hold music, a lengthy recording, or a phony survey. In the meantime, your phone bill shows outrageous per-minute prices, with money frequently flowing to the con artist.

• A phishing line is when a live person or automated message poses as a tech support service, your bank, or a government organization like the Social Security Administration or the IRS. They make their future scam attempt appear more genuine by using the callback as "proof" that you got in touch with them.

Step 3: The Theft

• The actual harm happens here. The scammer wants to exploit your call as a springboard for:

• Social engineering: They scare you with threats of a lawsuit, questionable activities, or a frozen account. They coerce you into providing a One-Time Password (OTP), your Social Security number, or your bank login information in order to "resolve" the issue.

• SIM Swap Prelude: In an attempt to move your phone number to their device, they may collect personal information from you during the conversation in order to subsequently pose as you to your mobile provider. They now have access to your text messages, including your bank's two-factor authentication details.

• Malware Links: They might send you a text message with a link to "verify your account" or "see details about the call," which takes you to a website that infects your phone with malware that steals data.

The Rules of Engagement: Protect Yourself

Things Not to Do:

• Never return missed calls from unknown numbers.

• If a recorded message instructs you to "press 1" or dial a different number in order to be taken off a list, DO NOT do so.

• Even if someone calls and says it's urgent, don't give them your passwords, verification codes, or personal information.

• Don't rush anything. Reputable companies will allow you time to confirm.

What to do in its place:

• Unknown callers should be routed to voicemail. Callers who are legitimate will leave a message.

• Make use of the call-blocking tools provided by your carrier and notify the FTC about spam numbers.

• If you're worried, give a verified number a call back. Hang up and call the customer support number on the back of your card or the company's official website if the caller says they are from your bank.

• Keep a close eye out for any fraudulent transactions on your accounts.
