The important and rapidly emerging new field known as 'cyber threat intelligence' explores the paradigm that defenders of computer networks gain a better understanding of their adversaries by understanding what assets they have available for an attack. In this book, a team of experts examines a new type of cyber threat intelligence from the heart of the malicious hacking underworld - the dark web. These highly secure sites have allowed anonymous communities of malicious hackers to exchange ideas and techniques, and to buy/sell malware and exploits. Aimed at both cybersecurity practitioners and researchers, this book represents a first step toward a better understanding of malicious hacking communities on the dark web and what to do about them. The authors examine real-world darkweb data through a combination of human and automated techniques to gain insight into these communities, describing both methodology and results.

Die Bedeutung der digitalen Infrastruktur, insbesondere von Netzwerken, ist in den letzten zehn Jahren kontinuierlich gestiegen. Das gilt gleichermaßen für die IT-Sicherheit. Denn ohne sichere Netzwerke können Technologien wie Künstliche Intelligenz oder das Internet der Dinge weder betrieben noch weiterentwickelt werden. Dieses Buch liefert das Fundament, um die Konzeption von TCP/IP- und IoT-Netzwerken und ihre Sicherheit in einer zunehmend vernetzten Welt zu verstehen. Es vereint praxisrelevantes Know-how mit den wissenschaftlichen Grundlagen und aktuellen Forschungsideen zu einem umfassenden Werk. Der Autor legt großen Wert darauf, die Grundlagen der Netzwerktechnik und der IT-Sicherheit verständlich und ausführlich darzustellen. Daneben greift er auch die folgenden Themen auf: · Die Kryptographie, ihre historischen und modernen Verfahren sowie ihre Anwendung beispielsweise in VPNs (Virtual Private Networks) · Die wichtigsten Angriffs- und Verteidigungsmethoden für Netzwerke · Die Sicherheit des Internets der Dinge und sein Einsatz etwa in Smart Buildings und Industriesteueranlagen Das Buch ist so konzipiert, dass Leserinnen und Leser mit einem eher praktischen Zugang zum Thema IT- und Netzwerksicherheit genauso profitieren wie jene mit einem mehr theoretischen Zugang. Durch zahlreiche Übungen – inklusive klassischer Klausuraufgaben – ist es sowohl für die Lehre als auch für das Selbststudium bestens geeignet. Zusatzmaterial wie Vorlesungsunterlagen und selektierte Lösungen zu den Übungen stehen online zum Download zur Verfügung.

This book presents a collection of state-of-the-art AI approaches to cybersecurity and cyberthreat intelligence, offering strategic defense mechanisms for malware, addressing cybercrime, and assessing vulnerabilities to yield proactive rather than reactive countermeasures. The current variety and scope of cybersecurity threats far exceed the capabilities of even the most skilled security professionals. In addition, analyzing yesterday’s security incidents no longer enables experts to predict and prevent tomorrow’s attacks, which necessitates approaches that go far beyond identifying known threats. Nevertheless, there are promising avenues: complex behavior matching can isolate threats based on the actions taken, while machine learning can help detect anomalies, prevent malware infections, discover signs of illicit activities, and protect assets from hackers. In turn, knowledge representation enables automated reasoning over network data, helping achieve cybersituational awareness. Bringing together contributions by high-caliber experts, this book suggests new research directions in this critical and rapidly growing field.

Due to a recent increase in popularity, Darknet hacker marketplaces and forums now provide a rich source of cyber threat intelligence for security analysts. This paper offers background information on Darknet hacker communities and their value to the cybersecurity community before detailing an operational data-collection system that is currently gathering over 300 threat warnings per week, with a precision of around 90% (Nunes 2016). Additionally, we introduce a game theoretic framework designed to leverage the exploit data mined from the Darknet to provide system-specific policy recommendations. For the framework, we provide complexity results, provably near-optimal approximation algorithms, and evaluations on a dataset of real-world exploits.

Das 'Dark Net' ist eine Unterwelt. Es besteht aus den geheimsten und verschwiegensten Ecken des verschlüsselten Webs. Ab und zu gerät ein Teil dieser Unterwelt in die Schlagzeilen, beispielsweise wenn eine Plattform für Online-Drogenhandel zerschlagen wird. Abgesehen davon wissen wir jedoch so gut wie nichts darüber. Bis heute. Basierend auf umfangreichen Recherchen, exklusiven Interviews und schockierendem, authentischem Material zeigt Jamie Bartlett, wie sich völlige Anonymität auf Menschen auswirken kann, und porträtiert faszinierende, abstoßende oder auch gefährliche Subkulturen, darunter Trolle und Pädophile, Dealer und Hacker, Extremisten, Bitcoin-Programmierer und Bürgerwehren.

This book provides readers with up-to-date research of emerging cyber threats and defensive mechanisms, which are timely and essential. It covers cyber threat intelligence concepts against a range of threat actors and threat tools (i.e. ransomware) in cutting-edge technologies, i.e., Internet of Things (IoT), Cloud computing and mobile devices. This book also provides the technical information on cyber-threat detection methods required for the researcher and digital forensics experts, in order to build intelligent automated systems to fight against advanced cybercrimes. The ever increasing number of cyber-attacks requires the cyber security and forensic specialists to detect, analyze and defend against the cyber threats in almost real-time, and with such a large number of attacks is not possible without deeply perusing the attack features and taking corresponding intelligent defensive actions – this in essence defines cyber threat intelligence notion. However, such intelligence would not be possible without the aid of artificial intelligence, machine learning and advanced data mining techniques to collect, analyze, and interpret cyber-attack campaigns which is covered in this book. This book will focus on cutting-edge research from both academia and industry, with a particular emphasis on providing wider knowledge of the field, novelty of approaches, combination of tools and so forth to perceive reason, learn and act on a wide range of data collected from different cyber security and forensics solutions. This book introduces the notion of cyber threat intelligence and analytics and presents different attempts in utilizing machine learning and data mining techniques to create threat feeds for a range of consumers. Moreover, this book sheds light on existing and emerging trends in the field which could pave the way for future works. The inter-disciplinary nature of this book, makes it suitable for a wide range of audiences with backgrounds in artificial intelligence, cyber security, forensics, big data and data mining, distributed systems and computer networks. This would include industry professionals, advanced-level students and researchers that work within these related fields.

The University of Arizona Artificial Intelligence Lab (AI Lab) Dark Web project is a long-term scientific research program that aims to study and understand the international terrorism (Jihadist) phenomena via a computational, data-centric approach. We aim to collect "ALL" web content generated by international terrorist groups, including web sites, forums, chat rooms, blogs, social networking sites, videos, virtual world, etc. We have developed various multilingual data mining, text mining, and web mining techniques to perform link analysis, content analysis, web metrics (technical sophistication) analysis, sentiment analysis, authorship analysis, and video analysis in our research. The approaches and methods developed in this project contribute to advancing the field of Intelligence and Security Informatics (ISI). Such advances will help related stakeholders to perform terrorism research and facilitate international security and peace. This monograph aims to provide an overview of the Dark Web landscape, suggest a systematic, computational approach to understanding the problems, and illustrate with selected techniques, methods, and case studies developed by the University of Arizona AI Lab Dark Web team members. This work aims to provide an interdisciplinary and understandable monograph about Dark Web research along three dimensions: methodological issues in Dark Web research; database and computational techniques to support information collection and data mining; and legal, social, privacy, and data confidentiality challenges and approaches. It will bring useful knowledge to scientists, security professionals, counterterrorism experts, and policy makers. The monograph can also serve as a reference material or textbook in graduate level courses related to information security, information policy, information assurance, information systems, terrorism, and public policy.
