The "grandkid in trouble" call

The phone rings. It's a voice you'd swear is your grandkid, or your son, or your daughter. They're crying. They're in some kind of trouble, an accident, an arrest, something scary, and they need money right now. And whatever you do, don't tell anyone.

Here's what's actually happening. A scammer grabbed a few seconds of that person's voice from a video online, ran it through a voice cloning tool, and now they can make that voice say anything. The voice is real enough to fool you. The story is built to scare you so badly you act before you think. That's the whole trick. The fear does the work.

These scams keep the same trick and just change the story, an arrest one month, a car wreck the next. I flag the new versions as they start going around.

Two things stop it cold

• A family safe word. Pick one word, today, that only your family knows. Not a birthday, not a pet's name, nothing a stranger could guess or look up. If someone calls claiming to be family in trouble and they can't say the word, it isn't them.
• Hang up and call back. Never send money off the first call. Hang up and call that person on the number you already have for them. If they pick up, fine and confused, the scam is dead. And if the caller tells you not to hang up or not to call anyone, that's your answer right there.

Set the safe word and you've handled the big one.
