"In this book, a team of experts examines a new type of cyber threat intelligence from the heart of the malicious hacking underworld - the darkweb. These highly secure sites have allowed anonymous communities of malicious hackers to exchange ideas, techniques and 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 darkweb 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."--Cover, page 4
