Searching for Malware: A Review of Attackers' Use of Search Engines to Lure Victims

Presented at DEF CON 18 (2010), July 31, 2010, 11 a.m. (50 minutes)

For many people, the first page they visit online is a search engine; in fact, in the US alone more than 14 billion searches per month happen on Google, Yahoo! and Bing. These searches are then siphoned into thousands of popular search terms that are ripe for attackers to exploit. Attackers understand the number of eyeballs and browsers that are at stake and have targeted their attacks against popular search engine results in order to reach the broadest audience possible. For the past five months, Barracuda Labs has been observing and measuring attackers' use of search engine results to host malware or redirect users to malicious sites, collecting data multiple times a day and checking for malicious content around the clock across Google, Yahoo!, Bing and Twitter. In this talk, we reveal statistical data about the search engines and terms that were most targeted. We will highlight key attacker trends, and examine the ability of traditional security approaches like anti-virus and URL filters to react to the rapid movements by the SEO poisoning attacks.
