Analysis of Exploit-kit Incidents and Campaigns Through a Graph Database Framework
Abstract: A great deal of automation can be achieved here by using public APIs such as VirusTotal, whois databases, IP blacklists, etc during the analysis and a first part of our work is dedicated to that. We will then show that this approach reveals patterns and clusters from which decisions can be made from a defensive perspective.
