Gone Rogue: An Analysis of Rogue Security Software Campaigns

In the past few years, Internet miscreants have developed a number of techniques to defraud and make a hefty profit out of their unsuspecting victims. A troubling, recent example of this trend is cyber-criminals distributing rogue security software, that is malicious programs that,by pretending to be legitimate security tools (e.g., anti-virus or anti-spyware), deceive users into paying a substantial amount of money in exchange for little or no protection.While the technical and economical aspects of rogue security software (e.g., its distribution and monetization mechanisms) are relatively well-understood, much less is known about the campaigns through which this type of malware is distributed, that is what are the underlying techniques and coordinated efforts employed by cyber-criminals to spread their malware.In this paper, we present the techniques we used to analyze rogue security software campaigns, with an emphasis on the infrastructure employed in the campaign and the life-cycle of the clients that they infect.
