Hacker Linux Uncovered

Going beyond the issues of analyzing and optimizing programs as well as creating the means of protecting information, this guide takes on the programming problem of, once having found holes in a program, how to go about disassembling it without its source code. Covered are the hacking methods used to analyze programs using a debugger and disassembler. These methods include virtual functions, local and global variables, branching, loops, objects and their hierarchy, and mathematical operators. Also covered are methods of fighting disassemblers, self-modifying code in operating systems, and executing code in the stack. Advanced disassembler topics such as optimizing compilers and movable code are discussed as well....

Tips for the practical use of debuggers, such as NuMega SoftIce, Microsoft Visual Studio Debugger, and Microsoft Kernel Debugger, with minimum binding to a specific environment are disclosed in this debugger guide. How debuggers operate and how to overcome obstacles and repair debuggers is demonstrated. Programmers will learn how to look at what is inside a computer system, how to reconstruct the operating algorithm of a program distributed without source code, how to modify the program, and how to debug drivers. The use of debugging applications and drivers in Windows and Unix operating systems on Intel Pentium/DEC Alpha-based processors is also detailed....

A description and analysis of the vulnerabilities caused by programming errors in Web applications, this book is written from both from the attacker's and security specialist's perspective. Covered is detecting, investigating, exploiting, and eliminating vulnerabilities in Web applications as well as errors such as PHP source code injection, SQL injection, and XSS. The most common vulnerabilities in PHP and Perl scripts and methods of exploiting these weaknesses are described, information on writing intersite scripts and secure systems for the hosted sites, creating secure authorization systems, and bypassing authorization. Uncovered is how attackers can benefit from the hosted target and why an apparently normal-working application might be vulnerab...
