What Are Kernel-Mode Rootkits?

www.it-ebooks.info Hacking Exposed™ Malware & Rootkits Reviews “Accessible but not dumbed-down, this latest addition to the Hacking Exposed series is a stellar example of why this series remains one of the best-selling security franchises out there. System administrators and Average Joe computer users alike need to come to grips with the sophistication and stealth of modern malware, and this book calmly and clearly explains the threat.” —Brian Krebs, Reporter for The Washington Post and author of the Security Fix Blog “A harrowing guide to where the bad guys hide, and how you can find them.” —Dan Kaminsky, Director of Penetration Testing, IOActive, Inc. “The authors tackle malware, a deep and diverse issue in computer security, with common terms and relevant examples. Malware is a cold deadly tool in hacking; the authors address it openly, showing its capabilities with direct technical insight. The result is a good read that moves quickly, filling in the gaps even for the knowledgeable reader.” —Christopher Jordan, VP, Threat Intelligence, McAfee; Principal Investigator to DHS Botnet Research “Remember the end-of-semester review sessions where the instructor would go over everything from the whole term in just enough detail so you would understand all the key points, but also leave you with enough references to dig deeper where you wanted? Hacking Exposed Malware & Rootkits resembles this! A top-notch reference for novices and security professionals alike, this book provides just enough detail to explain the topics being presented, but not too much to dissuade those new to security.” —LTC Ron Dodge, U.S. Army “Hacking Exposed Malware & Rootkits provides unique insights into the techniques behind malware and rootkits. If you are responsible for security, you must read this book!” —Matt Conover, Senior Principal Software Engineer, Symantec Research Labs www.it-ebooks.info This page intentionally left blank www.it-ebooks.info HACKING EXPOSED™ MALWARE & ROOTKITS: MALWARE & ROOTKITS SECURITY SECRETS & SOLUTIONS MICHAEL DAVIS SEAN BODMER AARON LEMASTERS New York Chicago San Francisco Lisbon London Madrid Mexico City Milan New Delhi San Juan Seoul Singapore Sydney Toronto www.it-ebooks.info Copyright © 2010 by The McGraw-Hill Companies.

Michael is also the developer of sebek for Windows, a kernel-based data collection and monitoring tool for honeynets. Michael previously worked at McAfee, Inc., a leader in antivirus protection and vulnerability management, as Senior Manager of Global Threats, where he led a team of researchers investigating confidential and cutting-edge security research. Prior to being at McAfee, Michael worked at Foundstone. Sean M. Bodmer, CISSP, CEH Sean M. Bodmer is Director of Government Programs at Savid Corporation, Inc. Sean is an active honeynet researcher, specializing in the analysis of signatures, patterns, and the behavior of malware and attackers. Most notably, he has spent several years leading the operations and analysis of advanced intrusion detection systems (honeynets) where the motives and intent of attackers and their tools can be captured and analyzed in order to generate actionable intelligence to further protect customer networks. Sean has worked in various systems security engineering roles for various federal government entities and private corporations over the past decade in the Washington D.C. metropolitan area. Sean has lectured across the United States at industry conferences such as DEFCON, PhreakNIC, DC3, NW3C, Carnegie Mellon CERT, and the Pentagon Security Forum, covering aspects of attacks and attacker assessment profiling to help identify the true motivations and intent behind cyber attacks. Aaron LeMasters, CISSP, GCIH, CSTP Aaron LeMasters (M.S., George Washington University) is a security researcher specializing in computer forensics, malware analysis, and vulnerability research. The first five years of his career were spent defending the undefendable DoD networks, and he is now a senior software engineer at Raytheon SI. Aaron enjoys sharing his research at both larger security conferences such as Black Hat and smaller, regional hacker cons like Outerz0ne. He prefers to pacify his short attention span with advanced research and development issues related to Windows internals, system integrity, reverse engineering, and malware analysis. He is an enthusiastic prototypist and enjoys developing tools that complement his research interests. In his spare time, Aaron plays basketball, sketches, jams on his Epiphone Les Paul, and travels frequently to New York City with his wife. www.it-ebooks.info About the Contributing Author Jason Lord Jason Lord is currently Chief Operating Officer of d3 Services, Ltd., a consulting firm providing cyber security solutions.
