Hang Up and Verify

She sounded exactly like your daughter. That is no longer evidence of anything.

Three seconds of audio from a voicemail greeting or a social media video is now enough to reproduce someone's voice saying anything at all. In its 2025 report the FBI recorded more than 22,000 complaints involving AI-enabled fraud and over $893 million in losses. Americans over 60 lost more than $7.7 billion to cybercrime in the same year, an increase of roughly 59 percent.

And the advice most families have been given is now worse than useless.

Listening for robotic pauses, flat delivery or odd breathing no longer works. It teaches people they have a skill they do not have, and then they act on it. If you have ever thought I would know my own child's voice, this book was written for you.

Stop trying to tell whether it is really them. Start proving it.

HANG UP AND VERIFY is a short, practical handbook for families facing AI voice cloning scams, deepfake calls and grandparent fraud. No apps. No subscriptions. Nothing to install. One evening to set up, then forty minutes a year.

Inside this book

• The callback rule, and the three ways families get it wrong
• A three-phrase system: a challenge, a response, and a duress word meaning I am really me, and I am not free
• How to choose a family safe word that cannot be guessed from your social media, an obituary or a wedding website
• Why "I can't remember, I've hit my head" must be treated exactly like a wrong answer
• The exact words to end a call with someone sobbing in your child's voice
• How to raise this with a parent who is certain they would never fall for it
• Four ten-minute family drills a year, because under pressure people do what they have practised
• The money rules: gift cards, wire transfers, safe accounts and the ten-minute pause
• What to do in the first hour if it has already happened, and how to survive the second wave
• Versions for caregivers, students, separated families and anyone who approves payments at work

Written for

Adult children protecting aging parents. Older adults targeted by grandparent scams, imposter calls and phone fraud. Caregivers and relatives worried about elder fraud and financial exploitation. Small business owners and anyone who authorises transfers. Anyone whose voice, or whose family's voice, exists anywhere online.

Written by a security analyst working in vulnerability management and incident response, this is the professional approach to identity verification, translated for a kitchen table and tested against the way real families actually behave under pressure.

If it really is them, hanging up costs ninety seconds. If it is not, it costs everything.
