A call in the middle of the night
Midnight, the phone rings. Her son's voice: Mom, I'm in trouble, send me $800 right now. The voice sounds exactly the same, but the caller isn't her son.
VOICE CLONE
Copying a voice from a short recording
That's a voice clone: AI copying a voice. Scammers only need a short recording, taken from a video you posted online, to copy a voice.
WARNING SIGNS
Three signs
Watch for three signs: they rush you, they ask you to send money or read out a one-time code (OTP), and they tell you not to tell anyone.
WHAT TO DO
Hang up and call back yourself
The surest way: hang up, then call back yourself on the number you already have saved. Don't call back the number that just called.
TEST THEM
Something only family knows
Or ask something only family would know, like what everyone had for dinner yesterday. A scammer can't answer.
PREVENT IT
Share less of your voice
Prevent it ahead of time: post fewer public videos with voices, especially of older family members and young kids.
