Module to provide an easy way to perform password attacks

Instance Method Summary collapse

Instance Method Details

#attack(users, passwords, opts = {}) {|CMSScanner::User| ... } ⇒ Object

Due to Typhoeus threads shenanigans, in rare cases the progress-bar might be incorrect updated, hence the ‘rescue ProgressBar::InvalidProgressError’

TODO: Make rubocop happy about metrics etc

rubocop:disable all

Parameters:

Options Hash (opts):

  • :show_progression (Boolean)

Yields:

  • (CMSScanner::User) —

    When a valid combination is found
