(Radio Iowa) – Iowans are being warned to be very careful when posting videos of themselves on social media. Jim Temmer, with the Better Business Bureau, says criminals are using audio from online videos to fake people’s voices in scam calls.

Scammers are banking on people’s trust of you to trick them into other scams, he says, like sending money transfers or giving up personal information.

The best way to prevent this from happening is to only share your videos with your friends and family, and Temmer warns, keep a close eye on friend requests to make sure they’re not from phony accounts.
