"An infamous hacking group called Cult of the Dead Cow (cDc) recently released a tool called Goolag Scanner, which simplifies and automates Google hacking.
In case you haven’t heard of it: Google hacking is a term used to describe complex search queries designed to uncover sensitive data on the web that have been archived via Google. For instance, suppose you misconfigure one of your web servers, accidentally exposing a directory that contains a commonly named password file. Using a specially crafted search query in Google, a hacker could easily find your vulnerable server and its unprotected password file. Johnny Long, a well-known white hat hacker and friend of the LiveSecurity team, maintains the official Google Hacking Database and wrote the de facto book on the subject, Google Hacking for Penetration Testers. If you want to learn more about Google hacking, I recommend reading Long’s book." – Content courtesy of WatchGuard Wire: RSS Feed | WatchGuard
