The Art of Computer Virus Research and Defense

Description:

Preface Preface Who Should Read This Book Over the last two decades, several
publications appeared on the subject of computer viruses, but only a few have
been written by professionals ("insiders") of computer virus research. Although
many books exist that discuss the computer virus problem, they usually target a
novice audience and are simply not too interesting for the technical professionals.
There are only a few works that have no worries going into the technical details,
necessary to understand, to effectively defend against computer viruses. Part of
the problem is that existing books have little if any information about the current
complexity of computer viruses. For example, they lack serious technical
information on fast-spreading computer worms that exploit vulnerabilities to
invade target systems, or they do not discuss recent code evolution techniques
such as code metamorphism. If you wanted to get all the information I have in
this book, you would need to spend a lot of time reading articles and papers that
are often hidden somewhere deep inside computer virus and security conference
proceedings, and perhaps you would need to dig into malicious code for years to
extract the relevant details. I believe that this book is most useful for IT and
security professionals who fight against computer viruses on a daily basis.
Nowadays, system administrators as well as individual home users often need to
deal with computer worms and other malicious programs on their networks.
Unfortunately, security courses have very little training on computer virus
protection, and the general public knows very little about how to analyze and
defend their network from such attacks. To make things more difficult, computer
virus analysis techniques have not been discussed in any existing works in
sufficient length before. I also think that, for anybody interested in information
security, being aware of what the computer virus writers have "achieved" so far is
an important thing to know. For years, computer virus researchers used to be
"file" or "infected object" oriented. To the contrary, security professionals were
excited about suspicious events only on the network level. In addition, threats
such as CodeRed worm appeared to inject their code into the memory of
vulnerable processes over the network, but did not "infect" objects on the disk.
Today, it is important to understand all of these major perspectives the file
(storage), in-memory, and network views and correlate the events using
malicious code analysis techniques. During the years, I have trained many
computer virus and security analysts to effectively analyze and respond to
malicious code threats. In this book, I have included information about anything
that I ever had to deal with. For example, I have relevant examples of ancient
threats, such as 8-bit viruses on the Commodore 64. You will see that techniques
such as stealth technology appeared in the earliest computer viruses, and on a
variety of platforms. Thus, you will be able to realize that current rootkits do not
represent anything new! You will find sufficient coverage on 32-bit Windows worm
threats with in-depth exploit discussions, as well as 64-bit viruses and "pocket
monsters" on mobile devices. All along the way, my goal is to illustrate how old
techniques "reincarnate" in new threats and demonstrate up-to-date attacks with
just enough technical details. I am sure that many of you are interested in joining
the fight against malicious code, and perhaps, just like me, some of you will
become inventors of defense techniques. All of you should, however, be aware of
the pitfalls and the challenges of this field! That is what this book is all about.
What I Cover The purpose of this book is to demonstrate the current state of the
art of computer virus and antivirus developments and to teach you the
methodology of computer virus analysis and protection. I discuss infection
techniques of computer viruses from all possible perspectives: file (on storage), in-
memory, and network. I classify and tell you all about the dirty little tricks of
computer viruses that bad guys developed over the last two decades and tell you
what has been done to deal with complexities such as code polymorphism and
exploits. The easiest way to read this book is, well, to read it from chapter to
chapter. However, some of the attack chapters have content that can be more
relevant after understanding techniques presented in the defense chapters. If
you feel that any of the chapters are not your taste, or are too difficult or lengthy,
you can always jump to the next chapter. I am sure that everybody will find some
parts of this book very difficult and other parts very simple, depending on
individual experience. I expect my readers to be familiar with technology and
some level of programming. There are so many things discussed in this book that
it is simply impossible to cover everything in sufficient length. However, you will
know exactly what you might need to learn from elsewhere to be absolutely
successful against malicious threats. To help you, I have created an extensive
reference list for each chapter that leads you to the necessary background
information. Indeed, this book could easily have been over 1,000 pages.
However, as you can tell, I am not Shakespeare. My knowledge of computer
viruses is great, not my English. Most likely, you would have no benefit of my work
if this were the other way around. What I Do Not Cover I do not cover Trojan
horse programs or backdoors in great length. This book is primarily about self-
replicating malicious code. There are plenty of great books available on regular
malicious programs, but not on computer viruses. I do not present any virus code
in the book that you could directly use to build another virus. This book is not a
"virus writing" class. My understanding, however, is that the bad guys already
know about most of the techniques that I discuss in this book. So, the good guys
need to learn more and start to think (but not act) like a real attacker to develop
their defense! Interestingly, many universities attempt to teach computer virus
research courses by offering classes on writing viruses. Would it really help if a
student could write a virus to infect millions of systems around the world? Will
such students know more about how to develop defense better? Simply, the
answer is no... Instead, classes should focus on the analysis of existing malicious
threats. There are so many threats out there waiting for somebody to understand
them and do something against them. Of course, the knowledge of computer
viruses is like the "Force" in Star Wars . Depending on the user of the "Force," the
knowledge can turn to good or evil. I cannot force you to stay away from the
"Dark Side," but I urge you to do so. /> class="navigation"> Copyright Pearson
