When the fake is good enough to fool you

Three books on family cybersecurity by Stmatu, CISSP — twenty years in security, and a parent and grandparent. One threat per book: the faked image, the blackmailed teenager, the voice on the phone that isn’t who it says it is.

Each is written for a parent with no technical background, each is built on a framework you can remember under pressure, and each stands alone — read them in any order, or read the one that matches what you are facing.

The Three Books

Deepfakes Exposed - How AI Can Steal Your Face, Clone Your Voice, and Target Your Family - Book 1 of The DEFEND Series

Deepfakes Exposed

How AI Can Steal Your Face, Clone Your Voice, and Target Your Family

Your child’s face and voice are now enough.

A single birthday photo, a clip from a school play, a ten-second voice note. That is all today’s AI needs to clone a child’s face, fake their voice, and target a family. The widest of the three books — start here if you want the whole landscape.

Teen Sextortion

What Every Parent Must Know Before the Message Arrives

Your teen won’t tell you. That’s the whole design.

Sextortion runs on shame and moves in hours, and a parent’s ordinary instincts — interrogate, confiscate, delete, pay once — all make it worse. Read this one if you are raising a teenager, or if a message has already arrived.

BOOK 3 · VERIFY FRAMEWORK

The Cloned Voice

What Every Family Must Know Before the Phone Rings

The voice on the phone is your grandson. It isn’t.

A few seconds of audio clones a voice your family trusts, and the call always arrives as an emergency, because urgency is what stops you checking. Read this one if an older relative could get a panicked call asking for money.

Which one do I need first?

Start with Deepfakes Exposed if you want the whole picture — what AI can now fake, how families are targeted, and what to lock down before anything happens.

Start with Teen Sextortion if you are raising a teenager. It is the one crisis where a parent’s instincts are reliably wrong, and it opens with the first five actions on page one.

Start with The Cloned Voice if an older parent or grandparent could get a panicked call asking for money — and share the safe word with them the same day.

Books 2 and 3 each open with a Crisis Quick-Start on page one, before the front matter, for the family that is already in the middle of it.
