Checkpwd 2.00 A12 released

23 Okt 2007 von Alexander Kornbrust.

I just uploaded checkpwd 2.00 A12. This first version of checkpwd  2.0 comes with a lot of new features making it the smartest and most convenient Oracle password checker around… (and it’s free).

2 weeks ago Laszlo released his password cracker woraauthbf becoming the fastest password cracker for Oracle (but not the smartest). Woraauthbf is working in offline mode only and does not use information from the database.

Checkpwd is connecting to the database (offline is possible too) and uses passwords and potential password candidates from the database for cracking Oracle passwords. This approach is often more successful than the normal dictionary based approach (see password of MGMT_VIEW in screenshot). Due to this technique checkpwd finds more passwords than woraauthbf and that’s the main goal of a password checking tool. Speed is not everything…

Another interesting but dangerous feature writes the found passwords into a file called foundpw.txt. The content of this file is used the next time, making the passwords dictionary more and more powerful. This feature is useful for cloned databases which are normal in company environments. Be careful with this file…

Here are some of the new features of checkpwd:

* support for Oracle 11g passwords
* support for APEX passwords (1.4-3.0.1)
* collect passwords from the database
* collect password candidates from the database
* option not to display the oracle password in command line
* crack passwords from the password history
* crack role passwords
* save checkpwd default configuration in a configuration file
* read username and password hashes from a file
* …

Feature-Requests and comments are welcome.
