Hashattack - Auditing Privilged Oracle Passwords
------------------------------------------------------------------------
SUMMARY
DETAILS
Hashattack is a tool that can be used to build a table of Oracle password
hashes from a dictionary file for a designated username.
Hashes are calculated by creating a user account similar to the target
account to be audited and repeatedly changing the password with "ALTER
USER" for each dictionary word, storing the hash for each password in a
table.
Once the table of hashes is built, a simple SELECT can be issued to
determine if the password hash for a target user is a simple dictionary
word:
SQL> select h.username, h.password, h.hash
2 from hashattack h, dba_users d
3 where d.password = h.hash and h.username = 'SYS';
USERNAME PASSWORD HASH
