GREENSBORO, N.C. — Some scams never go away. But they get more popular among scammers at different times. Right now, the social security scam is popping up across the country. 

Lacey Knight says she got a call that was so combative she started using an app to spot potential scam calls. "They got very angry, very aggressive over the phone," she says. 

Here is how the scam works:

Someone called claiming she was being investigated for fraud. They tried to get her information, but she knew better. 

The FTC says no government agency will ask for money on gift cards or wire transfers. They also don't call without warning. They say you won't get a call from government agencies out of the blue. If you get a call, the advice is simple, just hang up.
