Crimeware is a collection of chapters collectively written by 40-odd security researchers. Sometimes this approach is a formula for disaster, but here the end result is a solid book that covers a broad number of topics. Because each author or group of authors know their field well, they can delve fairly deeply when necessary, and their material is technically accurate. However, some of the chapters are boring and lifeless. This book blocked my reading queue for about 4 months, which is a sign I found the text unappealing. It took a flight from Amsterdam to convince me to finish it! Still, I agree with many of the other reviewers -- Crimeware is an impressive examination of malware, on a variety of fronts.
Chapter 8: Rootkits, by Prashant Pathak, was my favorite. I've read books on rootkits before, by Pathak's chapter presented the subject in a very understandable manner. His methodical and disciplined approach seemed very effective. He explained various approaches and terms, instead of assuming the reader knew what he was discussing already. I recommend reading chapter 8 before tackling other books on rootkits.
Chapter 1: Overview of Crimeware, by Aaron Emigh and Zulfikar Ramzan; Chapter 6: Crimeware in the Browser, by Dan Boneh, et al; and Chapter 7: Bot Networks, by James Hoagland, Zulfikar Ramzan, and Sourabh Satish addressed the core malware topics I would expect to appeal to the sorts of readers who frequent my blog. While several other chapters offered novel research, these three plus the rootkits chapter are probably most helpful to those defending networks.
