A new warning from the Federal Communications Commission can save you from an emerging phone scam.

The Commission is alerting consumers about a scam where callers are coaxed to say the word “yes” during a call and later use that recording of the response to authorize unwanted charges on the victim’s utility or credit card account. Fraudulent callers impersonate representatives from organizations that provide a service and may be familiar to the person receiving the call, such as a mortgage lender.

The FCC says the scam begins with a scammer asking “Can you hear me?” and the caller then records the consumer’s “yes” response.

If you believe you’ve been targeted by this scam, you should immediately report the incident to the Better Business Bureau’s Scam Tracker and to the FCC Consumer Help Center.

Here are some tips recommended by the FCC:

  • Don’t answer calls from unknown numbers
  • If you’re asked to hit a button to stop receiving calls just hang up
  • Write down number for scam call
  • Ask your phone service provider if it offers a robocall blocking service and consider registering all your numbers in the National Do Not Call Registry
