Link Farms Injecting Malware in Search Engine Results

According to Team Leader malware Researcher, Chris Larsen at Blue Coat System, similar to the malicious code inserted into the database by SQL attacks, likewise link farms "injects" malware into results of a search engine. And the trouble is not diminishing, said Larsen while addressing at a RSA conference held in San Francisco recently, as reported by the website esecurityplanet on February 29, 2012.

Larsen held the view that infecting search engine result is quite easy and at the same time, quite difficult for search engine operators also.

While speaking about the recent malware inception, Larsen also denoted that if the crooks have some plans to victimize the naïve, higher officials also have enough security measures to befall them.

Search engine are poisoning and targeting lead searchers or scam destinations. Initially, Black Hat technique forms link farms and fills the sites thousand of malware encrypted links and fake pages. Then, they utilize bots to infect the web with malware-infected links to the false sites by making all kind of crap comments on blogs and even in the forums. While discussing about all such facts, Larsen also showed a screen that was sought from a forum discussion containing computer-generated usernames in which people were responding each other with the links attached with them.
