One reasonably effective defense: "Okay, let me call you right back." Yes, there's always the whole "my phone is dead, I borrowed someone else's" or "I'm calling from a jail payphone", so I think it might become common practice to start making authentication phrases or "tell me something only we know".

Another pillar of basic trust that's being eroded on an industrial scale. Sigh.

I mostly answer unknown calls with monotone "hello" and then wait for their introduction before talking normally.

The opening example is of a person listening to their daughter’s voice on an unknown number, how would calling them back help? Or am I missing something obvious?

The example in the article says the police took her phone. Then her "attorney" gets on to talk instead.

Yes, having a secret code is probably the right answer. My wife's family always has, but mine doesn't. I suppose we should probably fix that.

I mostly just don't answer them unless it seems like something that may be legit.

What’s terrible is each time I am forced to call the bank, the more they try to tell me voice ID is secure and want me to provide my voice to authenticate. Never. Did ya’ll never play Uplink? With voice cloning as good as it is now, there’s no way a voice ID is secure enough for authentication.
