What this book is

Almost everyone who reads a book like this begins from the same position: nobody would bother with me, I'm not important, there's nothing interesting in my email. All of that is probably true, and none of it protects you, because you have misunderstood how this works.

Nobody chose you. You were not selected, researched, or targeted. Your email address appeared in a list. An automated system tried a password that leaked from a shopping site in 2019 against forty other services. The economics are industrial, and industrial economics do not care whether you are interesting. The consequences, however, are entirely personal: a compromised email account is not an inconvenience, it is the key to every other account you own. A cloned voice does not need to fool the world; it needs to fool your mother for ninety seconds.

What you get

  • 115-page designed PDF, readable on phone, tablet, and print
  • 14 chapters across four parts
  • Bonus section: checklists, cards, and the 30-Day Plan
  • Passwords, passkeys, and multi-factor authentication done properly
  • AI phishing, deepfake voice and video, and family codewords
  • Data brokers, what you leak, and a full After a Hack chapter

How it is written

Defensive, educational material for individuals and families. It contains no attack techniques. Threats are described only to the level needed to recognise them. Not a technical security manual, not a professional security assessment, and not legal advice. Not jurisdiction-specific: reporting bodies and liability rules for fraudulent payments differ by country. Security guidance ages, so the principles are durable and the mechanisms are not. If you are experiencing stalking, domestic abuse, or targeted harassment, some steps here can escalate danger. Contact a specialist organisation first.
