The number of security countermeasures against user-land exploitation is on the rise. Because of this, kernel exploitation is becoming much more popular among exploit writers and attackers. Playing with the heart of the operating system can be a dangerous game: This book covers the theoretical techniques and approaches needed to develop reliable and effective kernel-level exploits and applies them to different operating systems (Linux, Solaris, Mac OS X, and Windows). Kernel exploits require both art and science to achieve. Every OS has its quirks and so every exploit must be molded to fully exploit its target. This book discusses the most popular OS families-UNIX derivatives, Mac OS X, and Windows-and how to gain complete control over them. Concepts and tactics are presented categorically so that even when a specifically detailed exploit has been patched, the foundational information that you have read will help you to write a newer, better attack or a more concrete design and defensive structure.
- 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

As cyber-attacks dominate front-page news, as hackers displace terrorists on the list of global threats, and as top generals warn of a coming cyber war, few books are more timely and enlightening than Dark Territory: The Secret History of Cyber War, by Slate columnist and Pulitzer Prize-winning journalist Fred Kaplan.
Kaplan probes the inner corridors of the National Security Agency, the beyond-top-secret cyber units in the Pentagon, the "information warfare" squads of the military services, and the national security debates in the White House, to tell this never-before-told story of the officers, policymakers, scientists, and spies who devised this new form of warfare and who have been planning—and (more often than people know) fighting—these wars for decades.

The United States faces evolving cybersecurity threats from nation-states such as China, Russia, North Korea, and Iran, as well as cyber threats from criminal organizations and terrorist groups such as ISIS. These actors continue to develop and build more sophisticated cyber capabilities. These hackers now pose an even greater threat to the U.S. homeland and critical infrastructure. Cybersecurity more than ever is National security. In 2015, the U.S. was the victim of one of the most significant cyber attacks in its history. The breach at the Office of Personnel Management exposed the personal and security clearance information of 21.5 million current and former Government employees. In 2014, North Korea conducted a cyber attack on Sony Pictures that not only destroyed computers, but also was intended to stifle free speech and threaten American ideals. The Obama administration's lack of proportional responses to these cyber attacks has signaled to the world that there are no real consequences for such actions. Without a comprehensive National cybersecurity strategy that establishes deterrence, the future could bring an increasing number of adversaries that are willing to conduct cyber attacks against the United States.
