The book has good reviews and sounds very thorough. I plan to buy it at the weekend in Borders or Waterstones if they have it in, if not from Amazon - I will let you know what I think after I get it and read it.
The website contains also a database of search strings - the database is called "Google Hacking Database (GHDB)!". This is a great list broken down into categories such as advisories and vulnerabilities, error messages, files containing passwords, files containing juicy info, pages containing login portals, sensitive directories, vulnerable files and many more.
There are of course many Oracle security search strings in the database but there doesn't seem to be a search box for the database to isolate the all of the Oracle search strings or anyway to download all of a particular group of searches such as the Oracle ones.
There is also a list of "signatures" that were part of Nitesh's article that may be useful but again they are not Oracle specific.
