While forensic analysis has proven to be a valuable investigative tool in the field of computer security, utilizing anti-forensic technology makes it possible to maintain a covert operational foothold for extended periods, even in a high-security environment. Adopting an approach that favors full disclosure, the updated Second Edition of The Rootkit Arsenal presents the most accessible, timely, and complete coverage of forensic countermeasures. This book covers more topics, in greater depth, than any other currently available. In doing so the author forges through the murky back alleys of the Internet, shedding light on material that has traditionally been poorly documented, partially documented, or intentionally undocumented. The range of topics presented includes how to: -Evade post-mortem analysis -Frustrate attempts to reverse engineer your command & control modules -Defeat live incident response -Undermine the process of memory analysis -Modify subsystem internals to feed misinformation to the outside -Entrench your code in fortified regions of execution -Design and implement covert channels -Unearth new avenues of attack

Details. When paging is enabled, the linear address space is divided into fixed-size plots of storage called pages (which can be 4 KB, 2 MB, or 4 MB in size). These pages can be mapped to physical memory or stored on disk. If a program references a byte in a page of memory that's currently stored on disk, the processor will generate a page fault exception (denoted in the Intel documentation as # PF) that signals to the operating system that it should load the page to physical memory. The slot in.
Number of command-line options that can be fed to (db. exe as a substitute for setting up environmental variables: • -logo logFile Used in placed of _NT_DEBUG_lOGJllE_OPEN • -y Symbol Path Used in place of _NT_SYMBOL_PATH • -srcpath SourcePath Used in place of _NT_SOUR(E_PATH The following is a batch file template that can be used to invoke (db. exe. It uses a combination of environmental variables and command-line options to launch an application for debugging: setlocal set.
Symbol, it would be useful to know what it represents. Is it a function or a variable? If a symbol represents data storage of some sort (e.g., a variable, a structure or union), the display type command can be used to display metadata that describes this storage. For example, we can see that the _LIST_ENTRY structure consists of two fields that are both pointers to other _LIST_ENTRY structures. In practice, the _LIST_ENTRY structure is used to implement doubly-linked lists and you will see this.
Admit that much of the article was beyond me at the time, it definitely planted a seed that grew over time. Without a doubt, this book owes a debt of gratitude to pioneers like Greg who explored the far corners of the matrix and then generously took the time to share what they learned with others. I'm talking about researchers like Sven Schreiber, Mark Ludwig, Joanna Rutkowska, Mark Russinovich, Jamie Butler, Sherri Sparks, Vinnie Liu, H.D. Moore, the Kumar tag-team over at NVIabs, Crazylord, and.
