Below is an example of what I observed:

During one of my strolls through the dark alleys of the web I came across another interesting black hat search engine optimization technique: branch offices for counterfeit luxury goods installed within legitimate sites. At first observation, the website I saw selling counterfeits looked like any other. But, after a closer look, the URL appeared to be much longer than the typical domain-based URL like fakestuffseller.com. Instead it looked like this: http://legitimatesite.com/includes/ice/ _vti_cnf/lib/ brand/boots/brand-boots.php. I noticed an extra directory ‘/includes/‘ that looked out of place and perhaps would not be in the normal structure of this particular legitimate website. My next step was to test my theory and delete the extra crap (/includes/ice/ _vti_cnf/lib/brand/boots/brand-boots.php) from the URL, leaving it to be simply legitimatesite.com. As I has suspected this led me to a perfectly legitimate university website.
The two questions you are asking right now are “how?” and “why?”. Allow me to enlighten you. The “how” is similar to what I explained in another recent article I wrote regarding black hat search engine optimization techniques where hackers find weaknesses (like unlocked doors) in websites whose security software is not up to date. Once that vulnerability is detected, the hacker can install thousands of his own websites within your website without your knowledge and, perhaps, for years before you even notice anything is strange. The reason they do it is so that they can create tens of thousands of websites selling counterfeits. Since this is done on a mass scale, the criminal is only minimally affected when your lawyer takes down poor old legitimatesite.com. He has an unlimited supply. Now I’m going to finish my coffee.
