This book explores the interface between terrorism and the internet and presents contemporary approaches to understanding violent extremism online. The volume focuses on four issues in particular: terrorist propaganda on the internet; radicalisation and the internet; counter campaigns and approaches to disrupting internet radicalisation; and approaches to researching and understanding the role of the internet in radicalisation. The book brings together expertise from a wide range of disciplines and geographical regions including Europe, the US, Canada and Australia. These contributions explore the various roles played by the Internet in radicalisation; the reasons why terroristic propaganda may or may not influence others to engage in violence; the role of political conflict in online radicalisation; and the future of research into terrorism and the internet. By covering this broad range of topics, the volume will make an important and timely addition to the current collections on a growing and international subject. This book will be of much interest to students and researchers of cyber-security, internet politics, terrorism studies, media and communications studies, and International Relations.

Advances in digital technologies have provided ample positive impacts to modern society; however, in addition to such benefits, these innovations have inadvertently created a new venue for criminal activity to generate. Combating Violent Extremism and Radicalization in the Digital Era is an essential reference for the latest research on the utilization of online tools by terrorist organizations to communicate with and recruit potential extremists and examines effective countermeasures employed by law enforcement agencies to defend against such threats. Focusing on perspectives from the social and behavioral sciences, this book is a critical source for researchers, analysts, intelligence officers, and policy makers interested in preventive methods for online terrorist activities.

The war on terrorism has not been won, Gabriel Weimann argues in Terrorism in Cyberspace, the successor to his seminal Terror on the Internet. Even though al-Qaeda's leadership has been largely destroyed and its organization disrupted, terrorist attacks take 12,000 lives annually worldwide, and jihadist terrorist ideology continues to spread. How? Largely by going online and adopting a new method of organization. Terrorist structures, traditionally consisting of loose-net cells, divisions, and subgroups, are ideally suited for flourishing on the Internet through websites, e-mail, chat rooms, e-groups, forums, virtual message boards, YouTube, Google Earth, and other outlets. Terrorist websites, including social media platforms, now number close to 10,000. This book addresses three major questions: why and how terrorism went online; what recent trends can be discerned—such as engaging children and women, promoting lone wolf attacks, and using social media; and what future threats can be expected, along with how they can be reduced or countered. To answer these questions, Terrorism in Cyberspace analyzes content from more than 9,800 terrorist websites, and Weimann, who has been studying terrorism online since 1998, selects the most important kinds of web activity, describes their background and history, and surveys their content in terms of kind and intensity, the groups and prominent individuals involved, and effects. He highlights cyberterrorism against financial, governmental, and engineering infrastructure; efforts to monitor, manipulate, and disrupt terrorists' online efforts; and threats to civil liberties posed by ill-directed efforts to suppress terrorists' online activities as future, worrisome trends.

This book explores the use of the internet by (non-Islamic) extremist groups, drawing together research by scholars across the social sciences and humanities. It offers a broad overview of the best of research in this area, including research contributions that address far-right, (non-Islamic) religious, animal rights, and nationalist violence online, as well as a discussion of the policy and research challenges posed by these unique and disparate groups. It offers an academically rigorous, introductory text that addresses extremism online, making it a valuable resource for students, practitioners and academics seeking to understand the unique characteristics such risks present.

Recent acts of terrorism and hate crimes have prompted a renewed focus on the possible links between internet content and offline violence. While some have focused on the role that social media companies play in moderating user-generated content, others have called for Congress to pass laws regulating online content promoting terrorism or violence. Proposals related to government action of this nature raise significant free speech questions, including (1) the reach of the First Amendment's protections when it comes to foreign nationals posting online content from abroad; (2) the scope of so-called "unprotected" categories of speech developed long before the advent of the internet; and (3) the judicial standards that limit how the government can craft or enforce laws to preserve national security and prevent violence. At the outset, it is not clear that a foreign national could invoke the protections of the First Amendment. The Supreme Court has never directly opined on this question. However, its decisions regarding the extraterritorial application of other constitutional protections to foreign nationals and lower court decisions involving speech made by foreign nationals while outside of the United States suggest that the First Amendment may not apply in that scenario. In contrast, free speech considerations are likely to be highly relevant in evaluating the legality of (1) proposals for the U.S. government to regulate what internet users in the United States can post, or (2) the enforcement of existing U.S. laws where the government seeks to hold U.S. persons liable for their online speech. Although the government typically can regulate conduct without running afoul of the First Amendment, regulations that restrict or burden expression often do implicate free speech protections. In such circumstances, courts generally distinguish between laws that regulate speech on the basis of its content and those that do not, subjecting the former to more stringent review. A law that expressly restricts online communications or media promoting violence or terrorism is likely to be deemed a content-based restriction on speech; whereas a law that primarily regulates conduct could be subject to a less stringent standard of review, unless its application to speech turns on the message expressed. Whether such laws would survive First Amendment scrutiny depends on a number of factors. Over the past 50 years, the Supreme Court has generally extended the First Amendment's free speech protections to speech that advocates violence in the abstract while allowing the government to restrict or punish speech that threatens or facilitates violence in a more specific or immediate way. The subtle distinctions that have developed over time are reflected in the categories of speech that the court has deemed unprotected, meaning that the government generally can prohibit speech in these areas because of its content. These include incitement to imminent lawless action, true threats, and speech integral to criminal conduct. Although judicial decisions have helped to define the scope of some of these categories, open questions remain as to how they apply in the context of online speech. For instance, legal scholars have questioned what it means for speech to incite "imminent" violence when posted to social media. They have also asked how threats should be perceived when made in the context of online forums where hyperbolic speech about violence is common. The extent to which the government can regulate speech promoting violence or terrorism also depends on whether its law or action satisfies the applicable level of scrutiny that the Court has developed to evaluate measures that restrict or burden speech. In general, laws that regulate protected speech on political or ideological matters are subject to strict scrutiny, but in some cases, courts have concluded that the government's national security interests justify restrictions.

"In the recent years, terrorism and radicalization have (unfortunately) become something of a regular topic in the news, in movies and TV shows, and even in dinnertime conversations. It seems like everyone knows something and has a theory or two to explain the growing number of terrorist attacks around the world. Some blame it on Muslims, some on the news media and the Internet, and some on the CIA and the U.S. government. It has become difficult to judge the quality of all this information. Thus, it makes sense to ask for credentials of the messengers"--

Social media has been weaponized, as state hackers and rogue terrorists have seized upon Twitter and Facebook to create chaos and destruction. This urgent report is required reading, from defense experts P.W. Singer and Emerson T. Brooking.

Online Terrorist Propaganda, Recruitment, and Radicalization is most complete treatment of the rapidly growing phenomenon of how terrorists’ online presence is utilized for terrorism funding, communication, and recruitment purposes. The book offers an in-depth coverage of the history and development of online "footprints" to target new converts, broaden their messaging, and increase their influence. Chapters present the emergence of various groups; the advancement of terrorist groups’ online presences; their utilization of video, chat room, and social media; and the current capability for propaganda, training, and recruitment. With contributions from leading experts in the field—including practitioners and terrorism researchers—the coverage moves from general factors to specific groups practices as relate to Islamic State of Iraq and the Levant (ISIL), and numerous other groups. Chapters also examine the lone wolf phenomenon as a part of the disturbing trend of self-radicalization. A functional, real-world approach is used regarding the classification of the means and methods by which an online presence is often utilized to promote and support acts of terrorism. Online Terrorist Propaganda, Recruitment, and Radicalization examines practical solutions in identifying the threat posed by terrorist propaganda and U.S. government efforts to counter it, with a particular focus on ISIS, the Dark Web, national and international measures to identify, thwart, and prosecute terrorist activities online. As such, it will be an invaluable resources for intelligence professionals, terrorism and counterterrorism professionals, those researching terrorism funding, and policy makers looking to restrict the spread of terrorism propaganda online.

Terrorism and ideologically inspired violence are persistent and serious threats to U.S. national security. This report uses interviews to explore why and how 32 individuals joined extremist organizations and how some of them exited these groups.
