A Guide To Kernel Exploitation

A Guide to Kernel Exploitation: Attacking the Core discusses the theoretical techniques and approaches needed to develop reliable and effective kernel-level exploits, and applies them to different operating systems, namely, UNIX derivatives, Mac OS X, and Windows. Concepts and tactics are presented categorically so that even when a specifically detailed vulnerability has been patched, the foundational information provided will help hackers in writing a newer, better attack; or help pen testers, auditors, and the like develop a more concrete design and defensive structure. The book is organized into four parts. Part I introduces the kernel and sets out the theoretical basis on which to build the rest of the book. Part II focuses on different operating systems and describes exploits for them that target various bug classes. Part III on remote kernel exploitation analyzes the effects of the remote scenario and presents new techniques to target remote issues. It includes a step-by-step analysis of the development of a reliable, one-shot, remote exploit for a real vulnerabilitya bug affecting the SCTP subsystem found in the Linux kernel. Finally, Part IV wraps up the analysis on kernel exploitation and looks at what the future may hold. Covers a range of operating system families — UNIX derivatives, Mac OS X, Windows Details common scenarios such as generic memory corruption (stack overflow, heap overflow, etc.) issues, logical bugs and race conditions Delivers the reader from user-land exploitation to the world of kernel-land (OS) exploits/attacks, with a particular focus on the steps that lead to the creation of successful techniques, in order to give to the reader something more than just a set of tricks

"Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build"secure" operating systems - operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we examine past research that outlines the requirements for a secure operating system and research that implements example systems that aim for such requirements. For system designs that aimed to satisfy these requirements,we see that the complexity of software systems often results in implementation challenges that we are still exploring to this day. However, if a system design does not aim for achieving the secure operating system requirements, then its security features fail to protect the system in a myriad of ways. We also study systems that have been retro-fit with secure operating system features after an initial deployment. In all cases, the conflict between function on one hand and security on the other leads to difficult choices and the potential for unwise compromises. From this book, we hope that systems designers and implementers will learn the requirements for operating systems that effectively enforce security and will better understand how to manage the balance between function and security."--BOOK JACKET.

This text introduces the spirit and theory of hacking as well as the science behind it all; it also provides some core techniques and tricks of hacking so you can think like a hacker, write your own hacks or thwart potential system attacks.

This much-anticipated revision, written by the ultimate group of top security experts in the world, features 40 percent new content on how to find security holes in any operating system or application New material addresses the many new exploitation techniques that have been discovered since the first edition, including attacking "unbreakable" software packages such as McAfee's Entercept, Mac OS X, XP, Office 2003, and Vista Also features the first-ever published information on exploiting Cisco's IOS, with content that has never before been explored The companion Web site features downloadable code files

A guide to rootkits describes what they are, how they work, how to build them, and how to detect them.

Escalate your privileges on Windows and Linux platforms with step-by-step instructions and deepen your theoretical foundations Key FeaturesDiscover a range of techniques to escalate privileges on Windows and Linux systemsUnderstand the key differences between Windows and Linux privilege escalationExplore unique exploitation challenges in each chapter provided in the form of pre-built VMsBook Description Privilege Escalation Techniques is a detailed guide to privilege escalation techniques and tools for both Windows and Linux systems. This is a one-of-a-kind resource that will deepen your understanding of both platforms and provide detailed, easy-to-follow instructions for your first foray into privilege escalation. The book uses virtual environments that you can download to test and run tools and techniques. After a refresher on gaining access and surveying systems, each chapter will feature an exploitation challenge in the form of pre-built virtual machines (VMs). As you progress, you will learn how to enumerate and exploit a target Linux or Windows system. You'll then get a demonstration on how you can escalate your privileges to the highest level. By the end of this book, you will have gained all the knowledge and skills you need to be able to perform local kernel exploits, escalate privileges through vulnerabilities in services, maintain persistence, and enumerate information from the target such as passwords and password hashes. What you will learnUnderstand the privilege escalation process and set up a pentesting labGain an initial foothold on the systemPerform local enumeration on target systemsExploit kernel vulnerabilities on Windows and Linux systemsPerform privilege escalation through password looting and finding stored credentialsGet to grips with performing impersonation attacksExploit Windows services such as the secondary logon handle service to escalate Windows privilegesEscalate Linux privileges by exploiting scheduled tasks and SUID binariesWho this book is for If you're a pentester or a cybersecurity student interested in learning how to perform various privilege escalation techniques on Windows and Linux systems – including exploiting bugs and design flaws – then this book is for you. You'll need a solid grasp on how Windows and Linux systems work along with fundamental cybersecurity knowledge before you get started.
