Botnets are overlay networks built by cyber-criminals from hacked smartphones and computers. In this paper, we report a vulnerability of the air interface of 4G cellular networks, the Long Term Evolution (LTE), to Distributed Denial-of-Service (DDoS) attacks launched from botnets. The attack scenario constitutes of a bot-master instructing the botnet nodes to start sending or downloading dummy data...
Botnets, overlay networks built by cyber criminals from numerous compromised network-accessible devices, have become a pressing security concern in the Internet world. Availability of accurate mathematical models of population size evolution enables security experts to plan ahead and deploy adequate resources when responding to a growing threat of an emerging botnet. In this paper, we introduce the...
Botnets have become platforms to launch distributed denial-of-service attacks and coordinate massive e-mail spam campaigns, to name just a few of botnet-related nefarious activities. Apart from the wired networks, the increasingly Internet-enabled cellular wireless networks are also vulnerable to botnet attacks; a situation which motivates a thorough study of botnet expansion and the mathematical...
