bopscrk

bopscrk (Before Outset PaSsword CRacKing) is a tool to generate smart and powerful wordlists for targeted attacks.

Included in BlackArch Linux pentesting distribution and Rawsec's Cybersecurity Inventory since August 2019.

  • Targeted-attack wordlist creator: introduce personal info related to target, combines every word and transforms results into possible passwords. The lyricpass module allows to search lyrics related to artists and include them to the wordlists.

  • Customizable case and leet transforms: create custom charsets and transforms patterns trough a simple config file.

  • Wordlists exclusion: Exclude words from another wordlist (to avoid passwords that you have already tested).

  • Interactive mode and one-line command interface supported.

Requirements

  • Python 3 (secondary branch keeps Python 2.7 legacy support)
  • optional - to use lyricpass module:
    pip install lib/lyricpass/requirements.txt

Usage


  -h, --help         show this help message and exit
  -i, --interactive  interactive mode, the script will ask you about target
  -w                 words to combine comma-separated (non-interactive mode)
  --min              min length for the words to generate (default: 4)
  --max              max length for the words to generate (default: 32)
  -c, --case         enable case transformations
  -l, --leet         enable leet transformations
  -n                 max amount of words to combine each time (default: 2)
  -a , --artists     artists to search song lyrics (comma-separated)
  -x , --exclude     exclude all the words included in other wordlists
                     (several wordlists should be comma-separated)
  -o , --output      output file to save the wordlist (default: tmp.txt)
  -C , --config      specify config file to use (default: ./bopscrk.cfg)


How it works

  • You have to provide some words which will act as a base.
  • The lyricpass feature allows to introduce artists. The tool will download all his songs' lyrics and each line will be added as a new word. By default, artist names and a word formed by the initial of word on each phrase, will be added too.
  • The tool will generate all possible combinations between them.
  • To generate more combinations, it will add some common separators (e.g. "-", "_", "."), numbers and special chars frequently used in passwords.
  • You can use leet and case transforms to increase your chances.
  • You can provide wordlists that you have already tested against the target in order to exclude all this words from the resultant wordlist (-x).

Tips

  • Fields can be left empty.
  • You can use accentuation in your words.
  • In the others field you can write several words comma-separated. Example: 2C,Flipper.
  • If you want to produce all possible leet transformations, enable the recursive_leet option in configuration file.
  • You can select which transforms to apply on lyrics phrases found trough the cfg file.
  • Using the non-interactive mode, you should provide years in the long and short way (1970,70) to get the same result than the interactive mode.
  • You have to be careful with -n argument. If you set a big value, it could result in too huge wordlists. I recommend values between 2 and 5.
  • To provide several artist names through command line you should provides it comma-separated. Example: -a johndoe,johnsmith
  • To provide artist names with spaces through command line you should provides it quotes-enclosed. Example: -a "john doe,john smith"

Lyricpass

This feature is based in a modified version of a tool developed originally by initstring. The changes are made to integrate input and output's tool with bopscrk.

It will retrieve all lyrics from all songs which belongs to artists that you provide. By default it will store each artist, each phrase found with space substitution, each phrase found reduced to its initials (which will be transformed later if you have activated leet and case transforms).

Advanced usage

Customizing behaviour using .cfg file

  • In bopscrk.cfg file you can specify your own charsets and enable/disable options:

    • threads: number of threads to use in multithreaded operations
    • extra_combinations (like (john, doe) => 123john, john123, 123doe, doe123, john123doe doe123john) are enabled by default. You can disable it in the configuration file in order to get more focused wordlists.
    • separators_chars: characters to use in extra-combinations. Can be a single char or a string of chars, e.g.: !?-/&(
    • separators_strings: strings to use in extra-combinations. Can be a single string or a list of strings space-separated, e.g.: 123 [email protected]
    • leet_charset: characters to replace and correspondent substitute in leet transforms, e.g.: e:3 b:8 t:7 a:4
    • recursive_leet: enables a recursive call to leet_transforms() function to get all possible leet transforms (disabled by default). WARNING: enabled with huge --max parameters (e.g.: greater than 18) could take several minutes. Can be true or false.
    • remove_parenthesis: remove all parenthesis in lyrics found before any transform
    • take_initials: produce words based on initial of each word in lyric phrases found (if enabled with remove_parenthesis disabled, it can produce useless words)
    • artist_split_by_word: split artist names and add each word as a new one
    • lyric_split_by_word: same with lyrics found
    • artist_space_replacement: replace spaces in artist names with chars/strings defined in charset
    • lyric_space_replacement: same with lyrics found
    • space_replacement_chars: characters to insert instead of spaces inside an artist name or a lyric phrase. Can be a single char or a string of chars, e.g.: !?-/&(
    • space_replacement_strings: strings to insert instead of spaces inside an artist name or a lyric phrase. Can be a single string or a list of strings space-separated, e.g.: 123 [email protected]
  • Some transforms have extensive charsets preincluded. To use it instead of the basic, just uncomment the corresponding line.

  • Parameters configuration examples

    • Combine all the words using dots as separator, and same using commas
      separators_chars=.,
    • Convert all "a/A" occurrences into "4" and all "e/E" occurrences into "3"
      leet_charset=a:4 e:3

Weighted-words system
