How to use Msf::Auxiliary::AuthBrute to write a bruteforcer

The Msf::Auxiliary::AuthBrute mixin should no longer be used to write a login module, you should try our LoginScanner API instead. However, some of the datastore options are still needed, so let’s go over them right quick.

Regular options

  • USERNAME - (String) A specific username to authenticate as.
  • PASSWORD - (String) A specific password to authenticate with.
  • USER_FILE - (String) File containing usernames, one per line.
  • PASS_FILE - (String) File containing passwords, one per line.
  • USERPASS_FILE - (String) File containing users and passwords separated by space, one pair per line.
  • BRUTEFORCE_SPEED - (Integer) How fast to bruteforce, from 0 to 5.
  • VERBOSE - (Boolean) Whether to print output for all attempts.
  • BLANK_PASSWORDS - (Boolean) Try blank passwords for all users.
  • USER_AS_PASS - (Boolean) Try the username as the password for all users.
  • DB_ALL_CREDS - (Boolean) Try each user/password couple stored in the current database.
  • DB_ALL_USERS - (Boolean) Add all users in the current database to the list.
  • STOP_ON_SUCCESS - (Boolean) Stop guessing when a credential works for a host.

Advanced options

  • REMOVE_USER_FILE - (Boolean) Automatically delete the USER_FILE on module completion.
  • REMOVE_PASS_FILE - (Boolean) Automatically delete the PASS_FILE on module completion.
  • REMOVE_USERPASS_FILE - (Boolean) Automatically delete the USERPASS_FILE on module completion.
  • MaxGuessesPerService - (Integer) Maximum number of credentials to try per service instance. If set to zero or a non-number, this option will not be used.
  • MaxMinutesPerService - (Integer) Maximum time in minutes to bruteforce the service instance. If set to zero or a non-number, this option will not be used.
  • MaxGuessesPerUser - (Integer) Maximum guesses for a particular username for the service instance. Note that users are considered unique among different services, so a user at 10.1.1.1:22 is different from one at 10.2.2.2:22, and both will be tried up to the MaxGuessesPerUser limit. If set to zero or a non-number, this option will not be used.
