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 how to go about disassembling a program with holes without its source code. Detailing hacking methods used to analyze programs using a debugger and disassembler such as virtual functions, local and global variables, branching, loops, objects and their hierarchy, and mathematical operators, this guide covers 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, and a CD-ROM that contains illustrations and the source codes for the programs is also included.
How hackers, viruses, and worms attack computers from the Internet and exploit security holes in software is explained in this outline of antivirus software, patches, and firewalls that try in vain to withstand the storm of attacks. Some software's effectiveness exists only in the imaginations of its developers because they prove unable to prevent the propagation of worms, but this guide examines where security holes come from, how to discover them, how to protect systems (both Windows and Unix), and how to do away with security holes altogether. Unpublished advanced exploits and techniques in both C and Assembly languages are
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.

This comprehensive manual covers three areas in which system administrators must be proficient to successfully recover data: the structure and operating principles of the most popular file systems, automatic data recovery techniques, and manual recovery techniques used in cases of total data destruction. Data recovery from hard drives and optical storage in Windows, BSD, and Linux file systems is described, as are automatic recovery utilities, manual and automatic recovery of deleted files on ext2/ext3 partitions and NTFS partitions, formatted NTFS partitions and deleted UFS/FFS files, RAID data recovery, media restoration with physical damage, and data loss prevention.
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.
Zero day refers to software vulnerabilities or security flaws that are unknown to the software vendor and for which there is no available patch or solution. This means that the vulnerability can be exploited by attackers before it is discovered and fixed by the vendor. The term "zero day" comes from the fact that the vulnerability is known to attackers on the same day it is discovered, and before any patch or solution is available, leaving the software vulnerable to attacks. Zero day vulnerabilities are particularly dangerous because they can be used to launch targeted attacks against specific organizations or individuals, and can remain undetected for a long time. Attackers can use zero day exploits to gain unauthorized access to systems, steal sensitive information, or cause other types of damage. Organizations must reduce the risk of zero day vulnerabilities by keeping software up-to-date, applying security patches as soon as they become available, and monitoring for unusual activity that could indicate a zero day attack. Additionally, using security tools such as intrusion detection systems and endpoint protection can help detect and prevent zero day attacks.

A manual on protecting CDs against illegal copying, this book shows how crackers copy CDs using various access methods. The methods covered include the CDFS driver, cooked mode, SPTI, ASPI, the SCSI port, and the MSCDEX driver. Explained is how to prevent cracker break-ins using protections based on nonstandard CD formats such as the CD driver and weak CD sectors. Information on CD functioning fundamentals and tips related to CD protection in a format free of math and assembling-such as data formats, the scrambler, the Reed-Solomon coder/encoder, the CIRC coder/encoder, and a weak-sectors generator-are also provided. The main program interfaces, which provide direct control via peripheral devices on the application level in UNIX, Novell, and Windows 9x/NT/2000/XP, are considered, as is how to read and write RAW sectors.
