Be Careful With Your Search Results

Sep 1

 Update:  Learn about the latest BHSEO attack here.

Blackhat SEO (BHSEO) is currently one of the most prevalent distribution methods for Malware on the Internet.  It’s also one of the most dangerous methods because of the user-implied trust in search results.  A Forrester research study conducted in 2008 showed that 50 percent of Internet users trust content delivered by search engines. It’s no surprise that cyber criminals have been using malicious search results as a main monetization stream.

The Rogueware campaign we blogged about last week turned into a full blown BHSEO attack targeting relevant news topics such as, the California wildfires, Ted Kennedy’s death, DJ AM’s death, Mega Millions Lottery, Hurricane Danny, UFC 102, CNN and BBC breaking news among thousands of search terms and 123,000 links.  Upon clicking one of many malicious links in the top ranking search results, the victim is put through several redirections and finally taken to a fake scan website designed to infect and extort money.
