Malware writers are so creative.

The Koobface Gang, which is the group of malware authors responsible for the Koobface worm that has plagued Facebook and other social networking sites, showed their creativity last fall by using search engine optimization techniques to embed the worm in Web pages that are likely to get the most page views.

According to a recent report  from security vendor Websense, 95 percent of comments that purport to come from readers of blogs, chat rooms, and message boards are actually auto-generated messages containing spam or malware, showing just how infected social networking has become.

Social networking sites are a prime target for spreading spam and malware because they offer this ability for just about anyone to post comments, presenting hackers with a back door via which they can easily post links to malicious Web sites.  Considering how much malware has been found lurking on the pages of social networking sites, some readers must be following these links and offering hackers wonderful click-through rates.
