Title: Detecting fraudulent clicks from BotNets 2.0
Abstract:
DNS rebinding attacks allow fraudsters to create immense ephemeral bot
networks and to use those bots to commit click fraud. In this talk,
I'll explain the anatomy of a DNS rebinding attack, present a simple
analysis of the economics of such an attack, and explain the
implications for click-fraud detection schemes. Additionally, I'll
propose a defense that resists these attacks by leveraging the fact
that the (x, y) coordinates of an ad click reveal information about
the cognitive abilities of the clicker, allowing an ad network to
estimate the proportion of clicks originating from humans and from
bots.
