Cyber-Criminals Create Specialized Search Engines to Lead Users to Malicious Web Sites, According to PandaLabs

/PRNewswire/ -- PandaLabs, Panda Security's malware analysis and detection laboratory, today announced that it has uncovered evidence that cyber-criminals are starting to create their own search engines and use them to lead users to malicious pages, often created for distributing malware.

This new trend underlines how cyber-crime is becoming increasingly professional. Previously, cyber-crooks would use malicious SEO (Search Engine Optimization) or "blackhat SEO" techniques to improve the ranking of their pages among popular search engines. Now, they are beginning to use their own search engines which lead users directly to pages designed to infect or defraud them. One such malicious search engine, detected by PandaLabs, has already received approximately 195,000 visits.

These search engines operate as follows: When users enter a search term, the engine returns just five or six results. Clicking on any of these results will redirect the user to a Web page created specifically to distribute malware. The pages may include content such as pornographic videos, which ask users to download the latest version of "Web media player" in order to watch the clip. However, the file downloaded is really the adware WebMediaPlayer. These pages are also being used to distribute fake antivirus programs.

This technique is known as social engineering, and basically involves infecting users by enticing them to click a link or run a malicious file.

"We started searching for words and issues frequently exploited by cyber-crime, in this case swine flu, or celebrity names such as Britney Spears or Paris Hilton and this took us to pages created to distribute malware. But, we then found that even searching for our own names would reveal results that were in fact malicious pages," explains Luis Corrons, Technical Director of PandaLabs. "Strangely though, there is the occasional normal result among all the malicious ones. Perhaps this is to bolster the illusion that this is a genuine search engine."

To avoid falling victim to these attacks, PandaLabs advises users only to use trusted search engines, and to be wary of Web sites offering sensational videos or unusual stories.

"If on this kind of Web site you are asked to download a codec or any other kind of program to watch videos, there is a strong chance that it is really malicious code," warns Corrons.
