Vulnerable Application

This module attempts to use a password cracker to decode Windows based password hashes, such as:

  • LANMAN based passwords

  • NTLM based passwords

  • M$ CASH hashes (1 and 2) based passwords

  • NETNTLM and NETNTLMV2 based passwords

CommonJohnHashcat
lanmanlm3000
ntlmnt1000
mscashmscash1100
mscash2mscash22100
netntlmnetntlm5500
netntlmv2netntlmv25600

Sources of hashes can be found here: source, source2

Verification Steps

  1. Have at least one user with an uncracked windows based password hash in the database

  2. Start msfconsole

  3. Do: use auxiliary/analyze/crack_windows

  4. Do: set cracker of choice

  5. Do: run

  6. 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.

LANMAN

Crack LANMAN hashes. Default is true.

MSCASH

Crack MSCASH hashes. Default is true.

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.

NETNTLM

Crack NETNTLM hashes. Default is true.

NETNTLMV2

Crack NETNTLMV2 hashes. Default is true.

NTLM

Crack NTLM hashes. Default is true.

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.
