摘要: Botnets continue to pose a significant threat network-based applications and communications over the Internet. A key mitigation strategy has been take down command control infrastructure of botnets. The efficiency those methods not extensively studied. In this paper we investigate several observable characteristics botnet controls (C&C) estimate variability in survival rate these C&Cs factors that are related such variability. Furthermore, show different type efforts have impact. Kaplan-Meier analysis is performed evaluate C&C ratios particular case ZeuS botnet. Using lasso penalized Cox regression model, identify influence lifetime C&C. Location, malware family type, registrar, hosting popularity fundamental explain Our results location two affect more significantly lifetime. Thus, certain regions Asia prone stay online longer located Europe.
