Abstract: With the rapid growth of information technology, people’s daily activities have been gradually moving to cyberspace. Online activities also play an increasingly important role national economy. While the Internet greatly facilitated our daily life, more and more criminal activities that threaten our daily life, have also moved to cyberspace. Therefore, how to understand, evaluate, prevent, and combat cybercrimes have become the focus of attention of academia, industry, and law enforcement agencies. Recently, researchers pay much attention to the prevention, evaluation, and countermeasures of cybercrimes. However, until now, only a few researchers focus on the overview of cybercrime. Also, there is an urgent need for systemization of the entire cybercrime kill chain. This paper starts from some classic cybercrime attacks such as phishing, scam, and cryptojacking, and then an in-depth analysis of their supporting techniques is conducted, including blackhat SEO and typosquatting. To analyze the cybercrime kill chain, we also investigate the cybercrime infrastructures such as underground market, botnet, and money laundering. Finally, we discuss the existing challenges and trends of cybercrime research.
