From Wired senior writer Andy Greenberg comes the true story of the most devastating cyberattack in history and the desperate hunt to identify and track the elite Russian agents behind it.

"Much more than a true-life techno-thriller ... a tour through a realm that is both invisible and critical to the daily lives of every person alive in the 21st century." —Los Angeles Times

In 2014, the world witnessed the start of a mysterious series of cyberattacks. Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes grew ever more brazen. They culminated in the summer of 2017, when the malware known as NotPetya was unleashed, penetrating, disrupting, and paralyzing some of the world's largest businesses—from drug manufacturers to software developers to shipping companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. Hospitals went dark. NotPetya spread around the world, inflicting an unprecedented ten billion dollars in damage—the largest, most destructive cyberattack the world had ever seen.

The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in history: a group known as Sandworm. Working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike.

A chilling, globe-spanning detective story, Sandworm considers the danger this force poses to our national security and stability. As the Kremlin's role in foreign government manipulation comes into greater focus, Sandworm exposes the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield. It reveals how the lines between digital and physical conflict, between wartime and peacetime, have begun to blur—with world-shaking implications.

This book gives a thorough explanation of what computer viruses are, how they work, and how much computer users should worry about them. It is written to apply to all systems: micro, network, and mainframe and for both professional managers of computing systems and users of personal computers of all types, PCs, Macintoshes, and others. Robert Slade presents details of many of the most virulent of the known viruses and of the damage that they have done, as well as providing quidelines and recommendations to protect systems from infection. In addition, the book provides the widest possible range of reviews of the major anti-virus software packages available as well as many of the books on viruses. Contact addresses, telephone numbers, and electronic mail addresses are also given. In the event of a suspected virus infection, this book is the one that users will reach for! Included with the book is a diskette containing both four antiviral pieces of software for the PC and Macintosh and the complete virus catalog as produced by the Virus Test Centre at the University of Hamburg.

Able to propagate quickly and change their payload with each infection, polymorphic worms have been able to evade even the most advanced intrusion detection systems (IDS). And, because zero-day worms require only seconds to launch flooding attacks on your servers, using traditional methods such as manually creating and storing signatures to defend against these threats is just too slow. Bringing together critical knowledge and research on the subject, Automatic Defense Against Zero-day Polymorphic Worms in Communication Networks details a new approach for generating automated signatures for unknown polymorphic worms. It presents experimental results on a new method for polymorphic worm detection and examines experimental implementation of signature-generation algorithms and double-honeynet systems. If you need some background, the book includes an overview of the fundamental terms and concepts in network security, including the various security models. Clearing up the misconceptions about the value of honeypots, it explains how they can be useful in securing your networks, and identifies open-source tools you can use to create your own honeypot. There's also a chapter with references to helpful reading resources on automated signature generation systems. The authors describe cutting-edge attack detection approaches and detail new algorithms to help you generate your own automated signatures for polymorphic worms. Explaining how to test the quality of your generated signatures, the text will help you develop the understanding required to effectively protect your communication networks. Coverage includes intrusion detection and prevention systems (IDPS), zero-day polymorphic worm collection methods, double-honeynet system configurations, and the implementation of double-honeynet architectures.

The 1980's saw the advent of widespread (and potentially damaging) computer virus infection of both personal computer and mainframe systems. The computer security field has been comparatively slow to react to this emerging situation. It is only over the last two years that a significant body of knowledge on the operation, likely evolution and prevention of computer viruses has developed. A Pathology of Computer Viruses gives a detailed overview of the history of the computer virus and an in-depth technical review of the principles of computer virus and worm operation under DOS, Mac, UNIX and DEC operating systems. David Ferbrache considers the possible extension of the threat to the mainframe systems environment and suggests how the threat can be effectively combatted using an antiviral management plan. The author addresses the latest developments in "stealth" virus operations, specifically the trend for virus authors to adopt extensive camouflage and concealment techniques, which allow viruses to evade both existing anti-viral software and to avoid detection by direct observation of machine behaviour. A Pathology of Computer Viruses addresses a distinct need - that of the computer specialist and professional who needs a source reference work detailing all aspects of the computer virus threat.

Mr. Robot has been hailed, not only as one of the most haunting and unnerving dramas ever to appear on television, but also as the first accurate popular presentation of how computer hacking and cyberterrorism actually work. Mr. Robot and Philosophy is aimed at thoughtful fans of this addictive show who will welcome the opportunity to explore Elliot Alderson's world from a philosophical perspective. The developing story of Mr. Robot constantly raises ethical and metaphysical issues. What happens to our personal identity when it's extended into cyberspace and an array of electronic devices? Are we in control of our online lives or are we being controlled? What does our right to privacy mean in a world where millions of people can observe what we're doing and saying? Is a virtual currency true money and could it replace traditional money? Can there be healthy forms of drug addiction? Can some types of so-called mental illness be useful and beneficial? Does it make any sense to unleash destruction upon the existing corporate economic structures, and can we expect something better to emerge from the ruins of a digital meltdown?

This book provides a brief and general introduction to cybersecurity and cyber-risk assessment. Not limited to a specific approach or technique, its focus is highly pragmatic and is based on established international standards (including ISO 31000) as well as industrial best practices. It explains how cyber-risk assessment should be conducted, which techniques should be used when, what the typical challenges and problems are, and how they should be addressed. The content is divided into three parts. First, part I provides a conceptual introduction to the topic of risk management in general and to cybersecurity and cyber-risk management in particular. Next, part II presents the main stages of cyber-risk assessment from context establishment to risk treatment and acceptance, each illustrated by a running example. Finally, part III details four important challenges and how to reasonably deal with them in practice: risk measurement, risk scales, uncertainty, and low-frequency risks with high consequence. The target audience is mainly practitioners and students who are interested in the fundamentals and basic principles and techniques of security risk assessment, as well as lecturers seeking teaching material. The book provides an overview of the cyber-risk assessment process, the tasks involved, and how to complete them in practice.
