Phone scammers spend their days making trouble. They waste our time, tie up our phone lines and harass us with ugly language. Some do much, much worse. The FTC has heard from people who got calls from scammers saying, “I’ve kidnapped your relative,” and naming a brother, sister, child or parent. “Send ransom immediately by wire transfer or prepaid card,” they say, “or something bad will happen.”

They’re lying. They didn’t kidnap anyone, but they hope you’ll panic and rush to pay ransom before checking the story. Dozens of people told the FTC they got calls like this and paid $100 to $1,900 — often by wire transfer — to the kidnappers. To stop you from checking out the story, scammers order you to stay on the phone until the money is sent. There’s pressure to pay quickly, and the caller says not to contact anyone. And, of course, scammers demand payment by wire transfer or prepaid cards. Why? Because it’s difficult to trace or recover money sent that way.

The FBI calls this scam virtual kidnapping. Scammers scour the internet and social media sites, grabbing information about where people live, work, or travel, and names of friends and family. The cons use the details to pick a target and make their calls sound credible. To cut down on the information that scammers can find, think about limiting access to your networking pages — and encourage your family to do the same. Never post your Social Security number or account numbers online, and only share your phone number with your friends and contacts.

If you get a call like this, remember that it’s fake, no matter how scary it sounds. Even if it feels really real, never wire money or pay by prepaid card to anyone who asks you to. If you’re worried about the call, get off the phone and get in touch with the relative or friend in question – just to reassure yourself. And then report it to the FTC.
