Psudohash : Password List Generator That Focuses On Keywords Mutated By Commonly Used Password Creation Patterns

psudohash is a password list generator for orchestrating brute force attacks. It imitates certain password creation patterns commonly used by humans, like substituting a word’s letters with symbols or numbers, using char-case variations, adding a common padding before or after the word and more. It is keyword-based and highly customizable.

Pentesting Corporate Environments

System administrators and other employees often use a mutated version of the Company’s name to set passwords (e.g. Am@z0n_2022). This is commonly the case for network devices (Wi-Fi access points, switches, routers, etc), application or even domain accounts. With the most basic options, psudohash can generate a wordlist with all possible mutations of one or multiple keywords, based on common character substitution patterns (customizable), case variations, strings commonly used as padding and more. Take a look at the following example:

The script includes a basic character substitution schema. You can add/modify character substitution patterns by editing the source and following the data structure logic presented below (default):

transformations = [
{‘a’ : ‘@’},
{‘b’ : ‘8’},
{‘e’ : ‘3’},
{‘g’ : [‘9’, ‘6’]},
{‘i’ : [‘1’, ‘!’]},
{‘o’ : ‘0’},
{‘s’ : [‘$’, ‘5’]},
{‘t’ : ‘7’}
]

Individuals

When it comes to people, i think we all have (more or less) set passwords using a mutation of one or more words that mean something to us e.g., our name or wife/kid/pet/band names, sticking the year we were born at the end or maybe a super secure padding like “!@#”. Well, guess what?

Installation

No special requirements. Just clone the repo and make the script executable:

git clone https://github.com/t3l3machus/psudohash
cd ./psudohash
chmod +x psudohash.py

Usage

./psudohash.py [-h] -w WORDS [-an LEVEL] [-nl LIMIT] [-y YEARS] [-ap VALUES] [-cpb] [-cpa] [-cpo] [-o FILENAME] [-q]

The help dialog [ -h, –help ] includes usage details and examples.

Usage Tips

  • Combining options --years and --append-numbering with a --numbering-limit ≥ last two digits of any year input, will most likely produce duplicate words because of the mutation patterns implemented by the tool.
  • If you add custom padding values and/or modify the predefined common padding values in the source code, in combination with multiple optional parameters, there is a small chance of duplicate words occurring. psudohash includes word filtering controls but for speed’s sake, those are limited.
