Vulnerable Application
This module attempts to use a password cracker to decode AIX based password hashes, such as:
Formats:
Common | John | Hashcat |
---|
des | descript | 1500 |
Sources of hashes can be found here: source, source2
Verification Steps
Have at least one user with a des
password in the database
Start msfconsole
Do: use auxiliary/analyze/crack_aix
Do: set cracker of choice
Do: run
You should hopefully crack a password.
Actions
john
Use john the ripper (default).
hashcat
Use hashcat.
Options
CONFIG
The path to a John config file (JtR option: --config
). Default is metasploit-framework/data/john.conf
CRACKER_PATH
The absolute path to the cracker executable. Default behavior is to search path
.
CUSTOM_WORDLIST
The path to an optional custom wordlist. This file is added to the new wordlist which may include the other USE
items like USE_CREDS
, and have MUTATE
or KORELOGIC
applied to it.
DeleteTempFiles
This option will prevent deletion of the wordlist and file containing hashes. This may be useful for running the hashes through john if it wasn't cracked, or for debugging. Default is false
.
Fork
This option will set how many forks to use on john the ripper. Default is 1
(no forking).
INCREMENTAL
Run the cracker in incremental mode. Default is true
ITERATION_TIMEOUT
The max-run-time for each iteration of cracking
KORELOGIC
Apply the KoreLogic rules to Wordlist Mode (slower). Default is false
.
MUTATE
Apply common mutations to the Wordlist (SLOW). Mutations are:
'@' => 'a'
'0' => 'o'
'3' => 'e'
'$' => 's'
'7' => 't'
'1' => 'l'
'5' => 's'
Default is false
.
POT
The path to a John POT file (JtR option: --pot
) to use instead. The pot
file is the data file which records cracked password hashes. Kali linux's default location is /root/.john/john.pot
. Default is ~/.msf4/john.pot
.
SHOWCOMMAND
Show the command being used run from the command line for debugging. Default is false
USE_CREDS
Use existing credential data saved in the database. Default is true
.
USE_DB_INFO
Use looted database schema info to seed the wordlist. This includes the Database Name, each Table Name, and each Column Name. If the DB is MSSQL, the Instance Name is also used. Default is true
.
USE_DEFAULT_WORDLIST
Use the default metasploit wordlist in metasploit-framework/data/wordlists/password.lst
. Default is true
.
USE_HOSTNAMES
Seed the wordlist with hostnames from the workspace. Default is true
.
USE_ROOT_WORDS
Use the Common Root Words Wordlist in metasploit-framework/data/wordlists/common_roots.txt
. Default is true.
WORDLIST
Run the cracker in dictionary/wordlist mode. Default is true
Scenarios
Sample Data
The following is data which can be used to test integration, including adding entries to a wordlist and pot file to test various aspects of the cracker.

We'll set ITERATION_TIMEOUT 60
for a quick crack, and ShowCommand true
for easy debugging.
