Search spam, using techniques that manipulate the search results, is becoming more dangerous each and every day. Some search spammers go as far as hacking sites to inject link spam into unsuspecting web pages. And some go even further by polluting the search results with nasty malware.

Yesterday we covered a story about a serious malware issue in the search engines, where hundreds of pages were being returned by Google, Yahoo, Live, and other search engines that contained harmful malware. Today, a WebmasterWorld thread pointed me to Spammers hack Al Gore’s climate site from Vnunet. In the Al Gore example, hackers used a Wordpress loophole to inject links into the source code of the site, which were invisible to normal users but very visible to search engines.
