Chris Hadnagy has over 16 years' experience as a practitioner and researcher in the security field. His efforts in training, education, and awareness have helped to expose social engineering as the top threat to the security of organizations today. He established the world's first social engineering framework at http://www.social-engineer.org/, providing an invaluable repository of information for security professionals and enthusiasts. That site grew into a dynamic web resource including a podcast and newsletter, which have become staples in the security industry and are referenced by large organizations around the world. Chris also created the first hands-on social engineering training course and certification, Advanced Practical Social Engineering, attended by law enforcement, military, and private sector professionals. A sought-after writer and speaker, he has spoken and trained at events such as RSA and Black Hat. He is also the best-selling author of two books: Social Engineering: The Art of Human Hacking and Unmasking the Social Engineer: The Human Element of Security.
