This module uses John the Ripper to identify weak passwords that have been acquired as hashed files (loot) or raw LANMAN/NTLM hashes (hashdump). The goal of this module is to find trivial passwords in a short amount of time. To crack complex passwords or use large wordlists, John the Ripper should be used outside of Metasploit. This initial version just handles LM/NTLM credentials from hashdump and uses the standard wordlist and rules.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/analyze/jtr_windows_fast
msf auxiliary(jtr_windows_fast) > show actions
...actions...
msf auxiliary(jtr_windows_fast) > set ACTION < action-name >
msf auxiliary(jtr_windows_fast) > show options
...show and set options...
msf auxiliary(jtr_windows_fast) > run
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
