Internet worm infection continues to be one of top security threats and has been widely used by botnets to recruit new bots. In this work, we attempt to quantify the infection ability of individual hosts and reveal the key characteristics of the underlying topology formed by worm infection, i.e., the number of children and the generation of the worm infection family tree. Specifically, we first apply...
Peer-to-peer botnets formed by worm infection have become a real threat to the Internet and are expected to become rampant in the near future. In our previous work, we have analyzed the underlying botnet topology formed by worm infection, without considering potential user defenses. In this paper, we extend the study to characterize the evolution of the botnet structure when users patch or clean part...
