Jon "Smibbs" Erickson worked in the field of computer security with a background in computer science.[6] As of 2011, he worked as a vulnerability researcher and computer security specialist in northern California. A bootable CD is included with the book which provides a Linux-based programming and debugging environment for the users.
Content of 1st edition
The content of Exploiting (2003) moves between programming, networking, and cryptography. The book does not use any notable measure of real-world examples: discussions rarely bring up specific worms and exploits.
Programming
The computer programming portion of Hacking takes up over half of the book. This section goes into the development, design, construction, and testing of exploit code, and thus involves some basic assembly programming. The demonstrated attacks range from simple buffer overflows on the stack to techniques involving overwriting the Global Offset Table.
While Erickson discusses countermeasures such as a non-executable stack and how to evade them with return-to-libc attacks, he does not dive into deeper matters without known guaranteed exploits such as address space layout randomization. The book also does not cover the Openwall, GrSecurity, and PaX projects, or kernel exploits.
The front cover of Hacking shows the complete process: from reverse engineering to carrying out the attack, and developing an exploit for a program that is vulnerable to buffer overflow in its command-line arguments.
The content of Hacking: The Art of Exploitation Second Edition (2008), the introduction of the book states that hacking should only be done within the confines of the law, and only for productive reasons. Below are the chapters:
0x200 Programming: This chapter covers control structures and other basic aspects of programming.
0x300 Exploitation: This chapter covers exploit techniques such as memory corruption, Buffer overflows and format strings, especially using Perl and Bashshellcode.
0x400 Networking
OSI Model: In communication among computers through networking, the OSI Model is used. This model provides the standards that computers use to communicate.
0x500 Shellcode:Shellcode is a custom code written by a hacker for execution upon gaining control over a program.
0x600 Countermeasures: This part of the book is about having defenses and intrusion prevention systems to stop known hacking exploits.
0x700 Cryptology
This section needs expansion. You can help by adding to it. (July 2024)
