Right now if your brother texts you and says they are stuck somewhere and need you to wire them $500, you call them and verify it is legitimate. That is the best answer we have for users.

Once your brothers voice has been cloned and generative AI can deep fake his face on a video call, we are pretty much screwed.

I usually just make sure the number is right.

How would you do that if they're claiming they lost their phone and are thus calling for a pay phone or the phone in a police station?
