He has years of private vulnerability development and exploitation experience for his customers and himself.
Jack is also the author of Intrusion Detection with Snort, one of the best-selling security books in its first year of publication (2003). The book has been translated into several languages, including French and Japanese, and has received rave reviews from Linux Journal, Slashdot, and Information Security magazine.
Jack has appeared in USA Today, CNN, MSNBC, First Business, and other media outlets for his expert opinions on information security. He lives in Oak Park, Illinois, in the shadow of Frank Lloyd Wright’s home and studio, with his girlfriend Tracy and dog Quasi.

Chris is actively involved in vulnerability research and has published several white papers and security advisories on a number of products, including PGP, Windows, SQL Server, and Oracle. He splits his time evenly between research, coding, consulting, and drinking, and hopes at some point to add sleeping to the list.
Sinan Eren is a security researcher based in the Bay Area. He has done extensive work regarding exploitation of Unix vulnerabilities, developed advanced and robust methodologies for exploiting Kernel-level holes, and found many high-profile bugs in commercial and open source Unix software.
Neel Mehta works as an application vulnerability researcher at ISS X-Force, and, like many other security researchers, comes from a reverse-engineering background. His reverse-engineering experience was cultivated through extensive consulting work in the copy protection field, and has more recently been focused on application security. Neel has done extensive research into binary and source-code auditing and has applied this knowledge to find many vulnerabilities in critical and widely deployed network applications.
Riley Hassell, a Senior Researcher Engineer at eEye Digital Security, is responsible for the design and implementation of eEye Digital Security’s QA and research tool suite. He is responsible for the discovery of several highly exposed vulnerabilities released by eEye Digital Security.
