DOMAIN MALWARE FAMILY CLASSIFICATION

A method for classifying domains to malware families includes identifying a corpus of malicious domains, identifying one or more suspicious domains, extracting a timeframe corresponding to the one or more suspicious domains, calculating a rank coefficient between the one or more suspicious domains and a current seed domain of the corpus of malicious domains, determining whether the rank correlation coefficient exceeds a rank threshold for the one or more suspicious domains, comparing a number of suspicious domains whose correlation coefficients exceed the rank threshold to a relation threshold, and responsive to determining the number of suspicious domains whose correlation coefficients exceed the rank threshold exceeds the relation threshold, applying a tag to the suspicious domains indicating that the one or more suspicious domains correspond to a same malware family as the current seed domain.
