Visualizing the Hosting Patterns of Modern Cybercriminals

The Domain Name Service (DNS) forms the basis of all Internet hosting for companies, individuals and criminals alike. Passive DNS logging provides a domain history, linking it not only to Internet Protocol (IP) addresses, but to domain registrars, ISPs and geographic locations. This paper will demonstrate the applied utility of passive DNS records through pivots, relationships to Internet Service Providers (ISPs), and the power of link-nodal visualization. It will also show how 'bullet-proof' hosters layer their products from their legitimate bases of operations, package them, and provide resiliency to illegitimate purposes. The ultimate goal of the analysis, beyond education of how illicit hosting works, is to provide techniques for incident responders to employ in making intelligent decisions when selecting the most useful combination of layered defense techniques, either for efficiency or completeness, against an identified, mapped threat.


Note: You have to add .pdf on the end of the file. Not sure why SANS Reading room can't get that right, but whatever.
