Oracle Pwnage Part 3

Sorry no metasploit for this one.

But

I did get asked how to get the SCOTT/TIGER username and pass. I left a (hint) in the first blog post. But by request here is the link:

Second thing was that you may find yourself with some oracle hashes after some crafty (well not realy) sql queries. Something that probably looks like this:

[*] DBSNMP,E066D214D5421CCC
[*] SCOTT,F894844C34402B67
[*] XDB,88D8364765FCE6AF

There are a couple of crackers, but I like checkpwd from red-database security. http://www.red-database-security.com/software/checkpwd.html

Rainbow tables are also a good way to crack Oracle password ;-)
