Chapter 1: What Exactly is Identity Theft?

Identity theft is when someone uses your personal information without permission to commit fraud, theft, or other crimes. It’s not just about stolen credit cards — it’s about someone pretending to be you.

Types of Identity Theft

• Financial Identity Theft: Fraudsters open new credit cards, take loans, or make purchases under your name.
• Criminal Identity Theft: A criminal gives your information to police during an arrest.
• Medical Identity Theft: Fraudsters use your identity to obtain medical care, prescriptions, or insurance.
• Synthetic Identity Theft: Criminals combine real data (like a Social Security number) with fake names to create a “synthetic” person.
• Child Identity Theft: Kids are prime targets since parents rarely check their credit.

Real-World Cases

• A woman in Florida discovered over $100,000 in medical debt under her name — but she had never been hospitalized.
• In California, a 7-year-old had a car loan taken out in his name.

Identity theft takes many shapes, but the outcome is always the same: stress, financial loss, and months (or years) of recovery.

Chapter 2: How Cybercriminals Steal Your Identity

Identity theft doesn’t just happen when someone “hacks” your computer. Criminals rely on digital and physical methods to gather enough data to impersonate you.

Digital Attacks

• Phishing Emails and Texts: Fake alerts that trick you into revealing personal info.
• Data Breaches: Millions of records exposed when corporations are hacked.
• Malware and Keyloggers: Silent software that steals your logins.
• Social Media Oversharing: Security question answers posted openly.
• Public Wi-Fi Risks: Hackers intercept unencrypted traffic.

Physical Attacks

• Mail Theft: Stolen bills or credit card offers.
• Dumpster Diving: Digging through trash for documents.
• Shoulder Surfing: Watching you enter PINs or passwords.

The Dark Web Economy

Stolen identities are sold on underground forums. Full identity kits (“fullz”) sell for as little as $30–$100.

Blended Attacks

Thieves mix methods: stealing mail, phishing for logins, and buying leaked info to create a full identity profile.
