I’ve found today 2 resources which are connected to good old Google Hacking Database :

1. Googlehacks which is  a dedicated application for Windows / Linux / Mac and allows you to easily run specialized Google queries (a.k.a googledorks). I would say that it’s a "must" inclusion in”Web Hacking for Dummies".
2. Google Hack Honeypot which is a set of PHP scripts used to detect any Google hacking attempts targeting your site. Well, it might me one of your friends using the tool described at #1 above

I find the Google Hacking Honeypot specifically interesting because I think it might be used as an IDS-like PHP class / module to identify who’s pulling some intelligence reports on your website.
