- ItemOpen AccessBlack Market Botnets(2007-07-24) Friess, Nathan; Aycock, JohnBotnets have yet to be exploited to their full potential, because they have yet to take advantage of all the information available to them. The zombie computers that comprise a botnet have access to the private documents of the people that use the computers. A botmaster who controls the botnet can harvest the documents and sell them to third parties, creating a viable if illegal online business. We outline motivations for such a business model, as well as the mechanics of a possible implementation. We then present a variety of defenses against this scenario.
- ItemOpen AccessSpam Zombies from Outer Space(2006-02-14) Aycock, John; Friess, NathanHow can better email worms be created? How can spyware claim more victims? How can better spam be sent? It turns out that these three questions are all related. We look at the future threat posed by email worms, spyware, and spammers that use zombie machines in a new way: sophisticated data mining of their victims saved email. The end result skirts many defenses, and could trick even experienced users. We present new defenses that can be deployed now against this threat.
