The Social Engineering Playbook
How Hackers Exploit Human Nature — and How to Fight Back
By Shane Larson
About This Book
Most cyberattacks don't begin with a zero-day exploit. They begin with someone being believed.
The 2020 Twitter breach — Barack Obama, Elon Musk, Joe Biden, all compromised simultaneously — started with a phone call to a helpdesk employee. The Target breach, 40 million credit cards exposed, traced back to a phishing email sent to an HVAC contractor. The RSA breach, which destabilized the security infrastructure of the U.S. defense industry, came down to one Excel attachment that someone opened.
No code. No exploit. Just people doing what people do: trusting, deferring, complying.
Social engineering is the oldest attack vector in existence, and it's never been more effective. Not because people are getting less careful — but because AI has handed attackers capabilities that didn't exist five years ago. Voice clones that sound exactly like your CEO. Personalized phishing emails generated at industrial scale. Deepfake video used to authorize wire transfers. The human firewall isn't failing. It's just being outgunned.
The Social Engineering Playbook maps how these attacks actually work — the psychology behind them, the techniques that execute them, and the defenses that actually hold.
What's inside:
- The cognitive exploit stack — authority bias, urgency, reciprocity, and the mental shortcuts that attackers have reverse-engineered into reliable attack patterns
- The Mitnick methodology — how the most notorious hacker in U.S. history penetrated the most secure organizations without writing a single line of exploit code
- Every major technique, fully dissected — phishing, spear-phishing, vishing, smishing, pretexting, physical infiltration, and Business Email Compromise from setup to execution
- The billion-dollar blind spot — why BEC costs organizations more than ransomware and why most security training never addresses it
- AI and the deepfake shift — voice cloning, synthetic video, and what personalized phishing at scale looks like when the attacker has an LLM doing the targeting work
- Nation-state operations and supply chain attacks — when social engineering goes from opportunistic to industrial
- Defense that actually works — awareness programs, reporting cultures, simulation-based training, and organizational structures that don't collapse under a well-crafted pretext
Each chapter is built around how attacks unfolded in the real world: the Twitter hack, the RSA breach, the Target intrusion, SolarWinds, deepfake CEO fraud. The case studies aren't illustrations — they're the argument.
