Botnets, i.e., networks of compromised machines under a common control infrastructure, are commonly controlled by an attacker with the help of a central server: all compromised machines connect to the central server and wait for commands. However, t
Computer worms evolved continually, faster and smarter. Proactive P2P worms with new “gene” propagate over logical P2P overlay networks defined by peer relationship. Observations suggest that the node degrees of an unstructured P2P network are power
