Jim O'Gorman, a.k.a. Elwood, is a professional penetration tester working with CSC's StrikeForce. He is one of the founders of Social-Engineer.org and co-trainer in Offensive Security's most challenging class, Advanced Windows Exploits (AWE).
"You simply cannot go wrong with this book if you want to learn more about Metasploit, or even if you want to learn more about penetration testing. Hands down, my new favorite Metasploit book."
--Sam Stover, ;login: The Usenix Magazine, August 2012
"A valuable resource for people who are interested in security but don't have the time or money to take a training class on Metasploit."
"A book that should be on the shelf of any serious computer security professional. And if you're just starting to dabble in the world of network security, this is a great resource to start your journey."
--Thomas Duff, Duffbert's Random Musings
