I have had a few emails from people asking me about the hashattack 2.0 tool written by Josh Wright that can be used to pre-compute password hashes from a dictionary of common words for a specific database users. The results stored in a table can then be easily re-used for ongoing checks for the same user in the same database or any other database.
I announced this tool here a few posts ago and added it to my Oracle Security Tools page
but unfortunately I got the URL wrong. The URL on my tools page has now been corrected.
There is also currently a thread on my Oracle Security Forum
discussing this tool.
