Ransomware is a type of malicious software that prevents victims from accessing their computers and the information they have stored. Typically, victims are required to pay a ransom, usually using cryptocurrency, such as Bitcoin, to regain access. Ransomware attacks pose a significant threat to national security, and there has been a substantial increase in such attacks in the post-Covid era. In response to these threats, large enterprises have begun implementing better cybersecurity practices, such as deploying data loss prevention mechanisms and improving backup strategies. However, cybercriminals have developed a hybrid variant called Ransomware 2.0. In this variation, sensitive data is stolen before being encrypted, allowing cybercriminals to publicly release the information if the ransom is not paid. Cybercriminals also take advantage of cryptocurrency’s anonymity and untraceability. Ransomware 3.0 is an emerging threat in which cybercriminals target critical infrastructures and tamper with the data stored on computing devices. Unlike in traditional ransomware attacks, cybercriminals are more interested in the actual data on the victims’ devices, particularly from critical enterprises such as government, healthcare, education, defense, and utility providers. State-based cyber actors are more interested in disrupting critical infrastructures rather than seeking financial benefits via cryptocurrency. Additionally, these sophisticated cyber actors are also interested in obtaining trade secrets and gathering confidential information. It is worth noting that the misinformation caused by ransomware attacks can severely impact critical infrastructures and can serve as a primary weapon in information warfare in today’s age. In recent events, Russia’s invasion of Ukraine led to several countries retaliating against Russia. A ransomware group threatened cyber-attacks on the critical infrastructure of these countries. Experts warned that this could be the most widespread ransomware gang globally and is linked to a trend of Russian hackers supporting the Kremlin’s ideology. Ensuring cyber safety from ransomware attacks has become a national security priority for many nations across the world. The evolving variants of ransomware attacks present a wider and more challenging threat landscape, highlighting the need for collaborative work throughout the entire cyber ecosystem value chain. In response to this evolving threat, a book addressing the challenges associated with ransomware is very timely. This book aims to provide a comprehensive overview of the evolution, trends, techniques, impact on critical infrastructures and national security, countermeasures, and open research directions in this area. It will serve as a valuable source of knowledge on the topic.

This book explores the genesis of ransomware and how the parallel emergence of encryption technologies has elevated ransomware to become the most prodigious cyber threat that enterprises are confronting. It also investigates the driving forces behind what has been dubbed the ‘ransomware revolution’ after a series of major attacks beginning in 2013, and how the advent of cryptocurrencies provided the catalyst for the development and increased profitability of ransomware, sparking a phenomenal rise in the number and complexity of ransomware attacks. This book analyzes why the speed of technology adoption has been a fundamental factor in the continued success of financially motivated cybercrime, and how the ease of public access to advanced encryption techniques has allowed malicious actors to continue to operate with increased anonymity across the internet. This anonymity has enabled increased collaboration between attackers, which has aided the development of new ransomware attacks, and led to an increasing level of technical complexity in ransomware attacks. This book highlights that the continuous expansion and early adoption of emerging technologies may be beyond the capacity of conventional risk managers and risk management frameworks. Researchers and advanced level students studying or working in computer science, business or criminology will find this book useful as a reference or secondary text. Professionals working in cybersecurity, cryptography, information technology, financial crime (and other related topics) will also welcome this book as a reference.

The first expert synthesis of the diverse studies conducted on wild equids worldwide. Wild horses, zebras, asses, and feral equines exhibit intriguing and complex social structures that captivate the human imagination and elicit a wide range of emotions that influence conservation and management efforts. This book, spearheaded by Jason I. Ransom and Petra Kaczensky, brings together the world's leading experts on equid ecology, management, and conservation to provide a synthesis of what is known about these iconic species and what needs to be done to prevent losing some of them altogether. The most comprehensive conservation book on wild equids in decades, this title will enlighten not only equid researchers, but also mammalogists, conservationists, and equine professionals. Readers will find new insight into the lives of the world's horses, zebras, and asses, understand the basis of our relationships with these animals, and develop a greater understanding of where equids come from and why they are worth conserving. Included in this book are detailed, state-of-the-science syntheses on Social structure, behavior, and cognition Habitat and diet Ecological niches Population dynamics Roles of humans in horse distribution through time Human dimensions and the meaning of wild Management of free-roaming horses Captive breeding of wild equids Conservation of wild equids Conservation of migrations Reintroductions Genetics and paleogenetics

Eritrean refugees are being trafficked and enslaved in Libya, where they are tortured to force relatives to pay a ransom for their release. Labelled with a digital code, they are moved along in the possession of the traffickers through a series of black holes, in which their access to digital technologies and connectivity is highly controlled. They are tortured, abused, extorted and subjected to sexual violence. Many die along the way. If they make it to the Mediterranean Sea, they risk being intercepted and returned to Libya or dying at sea. Over the period of this study (201721), it is conservatively estimated that at least 200,000 men, women and children have fallen victim to human trafficking for ransom in Libya, and the cumulative value of this trade for that period is estimated at over 1 billion USD. This detailed ethnographic study identifies the routes, modus operandi, organisation, and key actors involved in the human trafficking for ransom of refugees and migrants, who are desperately in need of protection. The book is part of the GAIC Research Network and African studies series published by Langaa RPCIG and makes an important contribution to the literature on human trafficking, migration studies, African studies, modern slavery, social protection and governance.

Sharon Kay Penman follows up her acclaimed novel Lionheart with this vivid and heart-wrenching New York Times bestseller about the last event-filled years in the life of Richard I of England, Coeur de Lion. November 1192. After his bloody crusade in the Kingdom of Jerusalem, Richard and his crew are overcome by a sudden storm, its fierce winds propelling the ship onto the Sicilian shore. But this misfortune is just the beginning. Forced to make a dangerous choice, Richard finds himself in enemy territory, where he is captured—in violation of the papal decree protecting all crusaders—and handed over to the Holy Roman Emperor. Imprisoned in the notorious fortress at Trifels, from which few ever leave alive, Richard, for the first time in his life, experiences pure, visceral fear—while his mother, Eleanor of Aquitaine, moves heaven and earth to secure his release. Amid betrayals, intrigues, infidelities, wars, and illness, Richard’s courage and intelligence will become legend.
