In order to really use Google Hacking techniques, you have to have a knowledge base that directs your search and helps you recognize when you reach a destination. While checking on hq-teens.com to see if the are still on line feeding images of abused anorexic young girls (they are), I also checked the source code and was reminded of the ucj cookie and cgi image feed.
Since all the images are fed from links containing a /ucj/ directory, I figured I’d do a long shot and Google
link:*/ucj/* which amazingly worked better than the Google “site” or “inurl” commands and led to two sites. One was a dead kiddie porn site and the other http://www.ucj.com Interestingly this is a site which cannot be explored through the front door because entry is blocked to the home page. The page I found is a manual for the ucj porn delivery system and the backdoor is wide open.
The URL, http://www.ucj.com/docs/ucj45/c.html is still live and for those who care you can move up the directory tree by eliminating the c.html and then the ucj45 drectory until you reach docs where you are once again are shut out. Now recognizing the weak link, you can explore the site with
site:ucj.com and find
http://www.ucj.com/features.html which takes you to a list of 1951 porn sites some of which contain kiddie porn because some known kiddie porn sites are on the list.
Now searching through 1951 sites for kiddie porn is a pretty inefficient uses of time but this line of thought allowed me to target my Google Search and zero in on the really nasty sites with one simple entry into the search bar.
