Google AdWords Exploit Seen in the Wild
This is an explicit tool in adwords, believe it or not.<p>The feature is intended so that you can have a link "to" <a href="http://trackersRus.com/" rel="nofollow">http://trackersRus.com/</a> which forwards to <a href="http://ebay.com/" rel="nofollow">http://ebay.com/</a>, without the user seeing that bit of ugly.<p>It's been used in campaigns for years, I've reported probably hundreds of these distributing malware.
