Red Database Security has released more Oracle password algorithm information
Alex has also craeted a new page titled "Oracle Password Checker (Cracker)" which details checkpwd his Oracle password cracker. As I said last night there are two versions of this cracker available. The first has a simple password list, the second a 1.5 million word list. Links are available on Alex's page and I have also added them to my Oracle Security Tools page. Alex gives examples of both methods of running the tool and also mentions that a Linux version will be available soon.
