An Analysis of the Domain Names Linked to the Important World Events using a Longitudinal Measurement Approach

Since the lack of sufficient security mechanisms, domain system (DNS) has become the main operational infrastructure for cyber intruders to launch cyber-attacks. Therefore, how to discover and block the potential malicious domains and its corresponding IP addresses fast and accurately has become a hot research area as it is one of the most important method in preventing unknown cyber-attacks. In this paper, we proposed an approach to detect malicious domains by analyzing massive mobile web traffic data. We used multiple features to classify, including the textual features and the traffic statistics features of domains and presented three typical classifiers to compare the classifying effect of each. Spark framework is leveraged to speed up the calculation of a large-scale DNS traffic. The efficiency of our system makes us believe the approach can help a lot in the field of network security. The new features are harder to be tampered with and can help determine whether a domain is malicious from a more comprehensive perspective. We evaluate MalPortrait on the passive DNS traffic collected from real-world large ISP networks.
