Abstract
In this paper, we present a case study of visual analytics of a Malware Distribution Network (MDN), a connected set of maliciously compromised domains used to disseminate malicious software to victimize computers and users. We formally define the graph of an MDN to visualize top-level-domain (TLD) data collected from Google Safe Browsing reports in a temporal manner characterizing the topological structure. From the collected data, we were able to identify and label a TLD's role in malware distribution. The visual analytics provided insights on the topological structure of MDNs over time including highly connected and persistent TLDs and subnetworks.
