Extensively updated and expanded to reflect the evolving landscape of online crime, this fourth edition of Cybercrime and Society is a comprehensive and accessible introduction to this complex and fascinating topic.  But just what are cybercrimes? And who are the cybercriminals? You will learn how the internet and communication technologies present new challenges to individual and collective safety, social order and stability, economic prosperity and political liberty. From hacktivism and digital disobedience to online harassment and sexual exploitation, Cybercrime and Society is the definitive book for undergraduate and postgraduate students studying modules in cybercrime and cybersecurity.  The fourth edition covers new and contemporary issues such as AI and preventative approaches to counter cybercrimes and also includes two new chapters: • Online Falsehoods provides coverage of fake news, disinformation, and conspiracies, each of which have rapidly become a major online problem with significant consequences • Illegal Goods and Illicit Markets combines discussion of issues such as the trade in prohibited goods online and via crypto-markets with discussion of piracy and copyright crime In addition to the extensive updating and expansion of the topics covered in the 2019 edition, all kinds of new developments are introduced and assessed. New case studies and examples are presented, and the international scope and coverage of the book has been further expanded, with treatment of the Canadian and Australian contexts being given greater consideration.
