HACKING: THE ART OF EXPLOITATION. “Most complete tutorial on hacking techniques. Finally a book that does not just show how to use the exploits but how to. The rules of engagement have been irreversibly changed by the internet. This book sums up the urgent significance of the modern hacking threat. Erickson shows. Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy.

C Assembly differs from C because assembly is a low-level programming language , and when processed can communicate directly with the processor. When using C, which is a high-level programming language, the code must be compiled and sent to the kernel by making a system call, and then making a call to the processor. In other words, it is almost like taking the system calling to the kernel out of the picture when using assembly.

The Path to shellcode This part of shellcode is about how to inject a program with shellcode so it can be taken over. There are many examples of code in the book and ways to accomplish this task. Self-spawning shellcode Spawning shellcode is code that will be enabled when an exploit is found. It is shellcode that will be able to be run when a vulnerability is found in the program. The best way to accomplish this is shown in the book and by making sure the code is very small.

Port-binding shellcode This type of shellcode attaches itself to a network port. Once bound to a port it will listen for a TCP connection. After it finds the TCP connection there is a lot more programming involved and is shown vividly in the book. Connect-back shellcode This type of shellcode is mainly used when getting around firewalls.

Most firewalls are going to block port-binding shellcode from working because they are set up to only allow known services through the active ports. Connect-back shellcode initiates the connection back to the hacker's IP address so it will be coming out from the firewall instead of going into it.

Once again the code in the book depicts connect-back with the use of shellcode and ways to accomplish this. This part of the book is about having defenses and intrusion prevention systems to stop known hacking exploits. Countermeasures That Detect An administrator of the network has to be aware of when an exploit may be occurring. Using certain tools like reading logs or packet sniffing on the network are a few ways to catch exploits when they occur. System Daemons A System Daemon is a server program on a Unix system which receives and accepts incoming connections.

A daemon is a program which runs in the background and detaches from controlling the terminal in a certain way. At this point in the book there is some code shown on how to run a daemon program. Signals are also used in a Unix-based environment to make operating system calls. When a signal is type in the terminal it will immediately send an interrupt message to complete the task of whatever the signal was which was typed.

The uses of signals are displayed in some coding examples in the book. Tools of the Trade A hacker has a certain set of tools that he needs to help him when exploiting. An exploit script is a tool in which uses already written exploit code to find holes in the system or program. Using exploit scripts is easy for even a non-hacker to use because the code is already written in it.

A couple exams of some exploit tools are shown in the book and how to use them. Log Files As stated earlier log files are a way to check events that have been happening on a computer or network. For a hacker, having the ability to change what the log file says can help him not to be noticed. There is code and directions on how to change some log files in the book.

Overlooking the Obvious Another sign of a program being hacked is that it will no longer work correctly. Most of the time programs do not work correctly because the hacker has modified them do accomplish another task. A skilled hacker however can modify the program so it still works correctly and does what he wants it do. If a program is exploited there are ways to tell how it happened.

Finding out how a program was exploited can be a very tedious process since it usually starts with taking parts of the program and looking at them individually. Putting an exploited program back together again to see how it was exploited is shown in the book.

Advanced Camouflage When a hacker is exploiting a program his IP address can be written to a log file. Camouflaging the log files so that his IP address can not be detected is shown in the book. When an IP address is hidden, it is called spoofing the IP address.

The Whole Infrastructure The use of intrusion detection systems and intrusion prevention systems greatly helps avoid the risk of being exploited. Even firewalls and routers have log files that can show evidence of hacking. Making sure that outbound TCP connections cannot be processed is one way to limit being found. A few ways are shown in the book on how to use TCP connections so that it is easier to go undetected.

Payload Smuggling When using shellcode to exploit programs, it can be caught by intrusion detection systems. Usually the intrusion detection system will catch the programs that are already written and have noticeable shell code in them.

Most exploit programs will be caught because real hackers are not using them. There are ways to hide shellcode so it can be harder to detect. A couple of examples on how to hide shellcode are found in the book. Buffer Restrictions Sometimes there are restrictions put on buffers so that vulnerabilities cannot be exploited.

There are a few ways that the book depicts on how to get around buffer restrictions. Hardening Countermeasures The exploits that are found in this book have been around for a long time. It took hackers a while before they figured out how to take advantage of the vulnerabilities described in this book.

Memory corruption, a change of control, and the use of shellcode are the three easiest steps to exploitation. Nonexecutable Stack Most applications do not use the stack for any type of executing. One defense is to make the stack non-executable so that buffer overflows cannot be used in the exploitation of the program. This defense is very effective for stopping the use of shellcode in an application. However, there is a way to get around the use of a non-executable stack which is shown and described in the book.

Randomized Stack Space A randomized stack is a type of countermeasure used so that the hacker is unable to tell where the shellcode he implemented is. It randomizes the memory layout within the stack. Once again, there is also a way to get around this countermeasure with some examples in the book. Cryptology is the use of communicating secretly through the use of ciphers, and cryptanalysis is the process of cracking or deciphering such secret communications.

This chapter offers information on the theory of cryptology, including the work of Claude Shannon , and concepts including unconditional security, one-time pads , quantum key distribution, and computational security. Using the same key to encrypt and to decrypt messages is symmetric encryption. Asymmetric encryption involves using different keys public and private. This chapter gives some examples of both kinds of encryption, and how to use them.

A cipher is an encryption algorithm. Combining the use of a symmetric cipher and asymmetric cipher is called a hybrid cipher. Ways to attack ciphers and to get around some encryption methods are shown and described in the book. The chapter also shows methods to figure out encrypted passwords, including brute-force attacks and hash look-ups.

It also offers methods to get around wireless This book will teach you how to: Program computers using C, assembly language, and shell scripts Corrupt system memory to run arbitrary code using buffer overflows and format strings Inspect processor registers and system memory with a debugger to gain a real understanding of what is happening Outsmart common security measures like nonexecutable stacks and intrusion detection systems Gain access to a remote server using port-binding or connect-back shellcode, and alter a server's logging behavior to hide your presence Redirect network traffic, conceal open ports, and hijack TCP connections Crack encrypted wireless traffic using the FMS attack, and speed up brute-force attacks using a password probability matrix Hackers are always pushing the boundaries, investigating the unknown, and evolving their art.

What is not covered by this book are higher level attacks such as cross site s [This is a review of the German translation of the second edition. What is not covered by this book are higher level attacks such as cross site scripting, SQL injections, or the use of exploit frameworks such as Metasploit. In fact, this book is rather about the art of creating attack scripts or shellcodes that could later be employed by such a higher level framework. Even though the second chapter of the book is considered an introduction to C, debugging and a little bit of assembly, it is rather a fast-tracked revision of stuff you better already know.

Make sure to take a good look at the example programs in this part, as they will be used repeatedly later on! The third chapter builds directly on the second and introduces the memory layout of x86 programs, and how to cause mischief with some simple buffer overflows. This is a challenging topic when you meet it for first time, but the presentation here breaks it down into elementary steps with detailed debugger analyses, so with some patience it becomes quite palatable.

Particularly surprising to me where the attacks made possible by improper uses of C's printf function, mainly because I was not even aware of the huge flexibility this function offers there are hardly any resources to read this up. Indeed, you can learn quite a bit in this chapter on how the Linux operation system works that will not be easily found somewhere else, if you had even thought about looking it up in the first place. One confusing thing about this chapter is that shellcodes are used without any explanation of what they are, or even a remark that they will be introduced later in Chapter 5.

It is ok to accept them as black box code at this point. Then the text diverts into a concise but suprisingly readable introduction refresher of network protocols and their Linux programming interface. With the fundamentals established, we see how a network sniffing, denial-of-service and man-in-the-middle attacks, and port scanning are done using hand-crafted network packets.

In Chapter 5, shellcodes are introduced, and the knowledge gained in the previous parts of the book is gathered to create reverse shells. This is what lies at the heart of most hacking endeavours with the aim to get control over a remote computer! In many introductions to hacking or penetration testing, shellcodes will be merely presented as a black box tool to be generated by some high-level framework; therefore this chapter is particularly valuable.

For simplicity, the shellcodes are only developed for Linux, which is a bit unfortunate, as it is much harder to self-learn this under Windows. This subject is continued in the sixth chapter, where countermeasures against exploits are discussed, and also counter-countermeasures that help the shellcode avoid detection. Here, it actually shows that the book is already a bit dated, as several modern countermeasures are only discussed cursorily here, and also many of the exploits developed before in the book would not work on modern operating systems.

At the time of this writing early , I am not aware of any book or even web resource that gives a comprehensive introduction on how to reliably beat modern exploit countermeasures, though. However, it would be missing the point to demand from this book to be always up to date and provide a solution for everything. Its purpose is to provide a throrough understanding of the principles underlying program execution and what can give rise to vulnerabilities, and it does this very well.

The seventh and last chapter on cryptography is completely independent on the others and not strictly necessary to make the book complete. It gives a very brief introduction to the underlying mathematics, unfortunately with quite few typos in the equations both in the English original and the German translation.

I recommend reading up the mathematical foundations elsewhere and then come back to this chapter. As cryptography is probably the strongest pillar in the foundation of cyber security, there are only few possible attacks, and many of of them are only discussed briefly here due to the high effort of actually implementing them. The focus is then on brute-force attacks on password, which can have a moderate chance of success.

The author presents a password cracking attack developed by himself, which is very complicated and interesting, but of little practical value. In summary, this book, though a demanding read, is quite unique in its approach to teaching hacking, and as such very valuable.

It is a little bit dated, but that does not devalue any of its content, but rather asks for an update at some point. The rules of engagement have been irreversibly changed by the internet. This book sums up the urgent significance of the modern hacking threat. Erickson shows how computer manipulation can be a useful defensive mechanism, but one with an unavoidable vulnerability. Vital information can be instantaneously stolen, and individuals can be discretely monitored without an iota of their awareness.

Low level and hard to read Unlike other books about hacking, this book focuses on the technical details about exploits rather than using them with other tools. But this additional depth comes at a price: First of all, such low-level approaches are not very practical in many situations - rather than building your own port scanner, you would use a prebuilt one so you can focus on other things. Second, several exploits which are discussed in depth are limited to C because higher-level languages like Low level and hard to read Unlike other books about hacking, this book focuses on the technical details about exploits rather than using them with other tools.

Second, several exploits which are discussed in depth are limited to C because higher-level languages like Java generally prevent a lot of these things at the cost of reduced performance. This is a minor thing though, because the principles should work as well. Third, and most importantly, the book is pretty hard to read because of the technical details. As a consequence, this book is definitely not for beginners.

I would probably come back to this book if I wanted to learn specifically about low-level exploits in combination with C and Assembler, but I would definitely not recommend this book for just getting a basic understanding of hacking or knowledge of basic tools.

Jan 02, Itai rated it it was amazing. Let's say you are a carpenter that builds chairs. You've been building chairs for several years now and people seem to be pretty happy with them, and you are as well. One day a man comes to your shop and goes to one of your chairs. Taking his hand he presses down on a particular spot in the back post, causing the chair to fall apart. You've never paid too much attention to the nails you are using, somewhere in the beginning of your career as a carpenter you've chosen some brand of nails and continued using them ever since.

Again, you've never paid too much attention to your choice of lacquer, but you must admit the man has a good point. This is what this book does to computer programming. Erickson takes us through the vulnerabilities of certain functions, system calls, and Linux quirks to show us the weak spots, but by doing so - we learn more about the intricacies of our code. Hacking, and knowing how a certain hack works, serves us well even if we have good intentions, because 1 if we get any input from the user, we want to make sure we are not subject to any malicous code execution and 2 by learning about the weaknesses we gain a better understanding of code.

Both of these skills make us better programmers. The book goes through several major topics related to hacking, buffer overflows, code injection, writing shell-code, networking, and some basic cryptographic algorithms.

The same goes for anyone working on networking. Highly recommended, especially for low-level programmers and anyone who has an interest in hacking and writing more secure code. These chapters probably should have been just skipped. Judging by other reviews, if you indeed didn't know this already, it wasn't explained well enough. Don't use this book as a learn-to-code book, the author himself clearly isn't a software developer by profession. His own code examples of course ignoring the ones having vulnerabilities on purpose were often iffy at best.

So even though this book still contains many subjects still relevant today, it's showing its age. Many of the 'latest' defences against exploits discussed are at this time old techniques already. Book ends with a chapter on cryptography, which isn't a very good chapter and doesn't really fit in with the rest of the book. Should have been left out. Interesting things from my point of view - format string vulnerabilities - return address abuse, including all sorts of related challenges - writing assembly shell code, from very basic to polymorphic ASCII-characters only against IDS This book does not include anything about website vulnerabilities SQL injection, XSS, Feb 06, Sam rated it it was amazing.

Yeah, this book was dense The first chapter gets into C as simple as could be. May quite possibly be the only C programming book one could ever need. The others showed me a side of the internet and networking protocols that blew me away. You really see the technicalities behind the information systems we take for granted. A lot of the chapters are daunting at a glance but are really simple if you proceed slowly. I suggest following along with the examples especially on the networking session.

Overall one realizes that the term hacking really is just understanding systems far better than most even the creators and using these systems in creative ways that many may not have intended to. Definitely, one I'll keep coming to. Mar 18, Andreas Ellison rated it it was amazing. I read this book because I wanted to understand how hacking actually works. I could never imagine how one can "hack" a program and access valuable information through it. This book is an excellent introduction into some basic methods of exploiting some vulnerabilities in programs or networks.

It explains how the methods work in detail so that you can implement it yourself and teaches you any necessary knowledge to understand the concepts. No prior knowledge is needed for this book and it teaches I read this book because I wanted to understand how hacking actually works.

No prior knowledge is needed for this book and it teaches you a lot and quickly. The author also succeeds in conveying the hacker spirit and explaining what kind of people hackers really are! Excellent and fun way to learn about software exploitation, successfully hacking the exploit-riddled flavor of Linux that comes with the book is sure to earn you several dopamine rushes.

Purely of practice, learning or historical interest, as the techniques learned here are for exploiting bugs that are long patched on an even minimally recent and secure system, but a good introduction into the type of work and thinking hackers have to do. Mar 22, Ben Oliver rated it liked it. Spends too much time on one topic then runs out of time to get truly creative.

Sep 25, Noah Nadeau rated it it was amazing. Probably one of the most difficult books I've ever read, but only because it's packed full of deep level information. Definitely a must for anyone interested in learning Assembly or C coding, if only to avoid common pitfalls.

Whenever I begin to think that I'm maybe sort of intelligent, I read a book like this and am pleasantly reminded that I'm an incompetent moron when it comes to most topics, lol. Also, this is actually pretty basic stuff for hacking, apparently?! Jul 31, Idir Yacine rated it liked it Shelves: interesting. Or perhaps the book is directed more for someone with an already good sense about hacking?

Which is contradictory with the first few chapters. All said might give it another chance at a later time. Jan 07, Zaid Sparrow rated it really liked it. Read it briefly but didnt finish it. Because its so old, its very very basic. If you wanna read historic work yea read it but now there are many great options available for learners. Book is too technical and it's focused on pc hacking. Oct 06, Dora solano rated it it was amazing. Feb 01, Danial rated it liked it Shelves: technology.

Better utilized as a reference book to cherry pick topics than a deep dive from cover to cover. Excellent book!

I can't think of a way to summarize it without being over-dramatic, so it will just be said: I really liked it. The book, which will be referred to as simply Hacking , starts by introducing the author's description of hacking. Erickson takes a great approach by admitting that the common perception of hacking is rather negative, and unfortunately accurate in some cases.

However, he smoothly counters this antagonistic misunderstanding by presenting a simple arithmetic problem. A bit of creativity is needed to arrive at the correct solution, but creativity and problem-solving are two integral aspects of hacking, at least to Erickson. The introduction chapter sets an acceptable tone and proper frame of mind for proceeding with the technical material. This discussion has been archived. No new comments can be posted.

I have this book, and it certainly is a passable introduction for the complete novice. However, it's simply too cursory and outdated to impart any practical knowledge of exploit development or vulnerability discovery. Fortunately, there are still a few good books out there on the subject. If you want to understand exploit development I highly recommend Koziol's "The Shellcoder's Handbook". Although you can pick up a used first edition since the second didn't seem to add much. If you want to understand vulnerability discovery I strongly recommend Dowd's "The Art of Software Security Assessment" which has quickly become the bible on finding security bugs.
