Harden the human firewall against the most current threats

Social Engineering: The Science of Human Hacking reveals the craftier side of the hacker's repertoire-why hack into something when you could just ask for access? Undetectable by firewalls and antivirus software, social engineering relies on human fault to gain access to sensitive spaces; in this book, renowned expert Christopher Hadnagy explains the most commonly-used techniques that fool even the most robust security personnel, and shows you how these techniques have been used in the past. The way that we make decisions as humans affects everything from our emotions to our security. Hackers, since the beginning of time, have figured out ways to exploit that decision making process and get you to take an action not in your best interest. This new Second Edition has been updated with the most current methods used by sharing stories, examples, and scientific study behind how those decisions are exploited.

Networks and systems can be hacked, but they can also be protected; when the "system" in question is a human being, there is no software to fall back on, no hardware upgrade, no code that can lock information down indefinitely. Human nature and emotion is the secret weapon of the malicious social engineering, and this book shows you how to recognize, predict, and prevent this type of manipulation by taking you inside the social engineer's bag of tricks.

"Chris Hadnagy's new book Social Engineering: The Science of Human Hacking is a great read for any audience interested in the subject of social engineering, detailing the exact steps from OSINT to execution in order to infiltrate any target." --Kevin Mitnick, author, speaker, and consultant

Mount a Stronger Defense by Mastering the Hackers' Most Reliable Techniques

In the fortress of defense we build around our data, the human element is always the weakest link. Hackers--both good and bad--employ a specific set of tricks to gain access to sensitive information, using "human hacking" techniques to convince people to hand over passwords, transfer sensitive files, wire large sums of money, and willingly commit other acts that are not in their own best interests. Social Engineering: The Science of Human Hacking details the human hacker's skill set to help security professionals identify and remedy their own system's weaknesses. Beginning with an in-depth exploration of communication modeling, tribe mentality, observational skills, manipulation, and other fundamentals, the discussion moves on to actionable guidance for identifying, fighting, and preventing such attacks in your own organization.

Author Christopher Hadnagy's updated second edition provides fresh insight into the latest social engineering trends and enduring classics, including case studies ripped from the headlines--as well as his own real-world experiences. Featuring how-to guidance on elicitation, pretexting, information gathering, tail-gating, shoulder surfing, phishing, and much more, this book dives deep into how humans can be influenced to make compromising decisions.

"Back in the late 70's, I started using social engineering tradecraft to obtain free bus rides as an adolescent, intercepting NSA phone calls in high school, to finally compromising any system of interest as a young adult. My motivation was pursuit of knowledge, challenge, and the seduction of adventure.

Fast forward to today, I still find that social engineering is the number one way in when conducting penetration testing. And I'm not alone. Nation states, criminal hackers, and hacktivists use the same tactics to disrupt businesses to steal money and/or proprietary information, and in some cases even change the course of a country's election."
--Kevin Mitnick, author, speaker, and consultant
