Measuring and Defending Against Search Result Poisoning

Search-result poisoning–the technique of fraudulently manipulating web search results–has become over the past few years a primary means of advertisement for operators of questionable websites. I will first describe the evolution of search-result poisoning using data on over five million search results that we collected over nearly four years. I will then discuss the design, implementation and evaluation of a novel classification system which predicts, whether a given, not yet compromised website will become malicious in the future. Such a system could be proactively used at scale to prevent compromises of vulnerable web servers, in turn making search-poisoning attacks far more difficult.
