When the Enemy Already Has Your Password
Robert Hanssen walked classified documents through frozen Virginia woods for 22 years. A 17-year-old in Tampa seized every famous person's Twitter. North Korean engineers sit in your company's Slack right now, writing code and wiring their paychecks to Pyongyang.
16 true stories. The spies, the leakers, the saboteurs, and the accidental catastrophes—told like a thriller.
"Every cybersecurity breach you've heard of has one thing in common: someone with a badge, a password, and a reason to use them wrong. This book is about those people—and the billions of dollars of wreckage they left behind."
— From the Prologue
Each chapter drops you into a moment of crisis—a person, a place, and an awful realization. No lectures. Just stories that happen to teach you everything about insider threats.
Written like Richard Preston's The Hot Zone crossed with a true-crime podcast. You'll learn more about insider threats from these stories than from any certification course.
Every chapter drops you into a moment of crisis. No preamble. No context. Just a person making the worst decision of their life.
The MICE framework — Money, Ideology, Compromise, Ego. Understand why trusted people betray, and you'll see the warning signs before the damage hits.
$2.6 billion in stolen IP. 700,000 classified documents. An entire country's intelligence assets burned. These aren't hypotheticals.
China's Thousand Talents. North Korea's ghost workforce. Russia's 22-year mole. Nation-state insider operations dissected in detail.
UEBA systems, behavioral analytics, zero-trust architecture — explained through the stories of the breaches that demanded them.
WSJ-style black-and-white stipple illustrations open every chapter — from FBI dead drops in frozen parks to deepfake interview screens glitching in real time.
Ian Trimble is a cybersecurity instructor and practitioner who has spent years training professionals to detect, prevent, and respond to the threats that keep CISOs awake at night.
With experience spanning incident response, threat intelligence, and security architecture, Ian brings the rare combination of technical depth and narrative skill needed to tell these stories the way they deserve to be told — as thrillers that happen to be true.
The Insider is his second book, following the neo-noir cyberpunk novel The Halcyon Key.
The most dangerous cybersecurity threat isn't a hacker in a hoodie — it's the person who already has your password.
