Google Poisoning - Be careful with Internet searches
This article provides a good update related to malicious links being embedded in returned search results. Folks should always avoid unusual links and keep AV/FW protection up-to-date. The current malicious links have domain names ending in "cn" (representing China, although they could be hosted from anywhere and this could change as this sophisticated attack continues).
VIRUS EXPERTS WARN OF 'GOOGLE POISONING'
QUOTE: You might want to take an extra half-second the next time you click on search engine results to make sure you know where you're going. Computer criminals have refined a sinister technique for tricking Web surfers into clicking on infected Web pages, turning search engines like Google into unwitting partners.
It's known as “Google poisoning,” because Google is the biggest target, but it can impact any search engine. Criminals construct booby-trapped Web pages, then dupe search engines into giving them high rankings.
A Google spokeswoman who declined to be identified said the company is aware of the problem and working to keep its results clean. "Google works hard to preserve the quality of our index,” the company said in a statement. “We actively identify sites that serve malware or abuse our quality guidelines in other ways."
No one knows how successful the tactic is, though Eckelberry points out the criminals wouldn't keep doing it if it didn't work. Still, even an attack of 40,000-50,000 fake Web sites still represents an infinitesimal portion of the sites in Google's index, making the odds of any individual consumer encountering a poisoned Google link still quite small. "I don't want people to get scared of Google," he said. “Google is impressive with how quickly they remove bad sites.”
