Weakpass – Rule-Based Online Generator To Create A Wordlist Based On A Set Of Words

The tool generates a wordlist based on a set of words entered by the user.

For example, during penetration testing, you need to gain access to some service, device, account, or Wi-Fi network that is password protected. For example, let it be the Wi-Fi network of EvilCorp. Sometimes, a password is a combination of device/network/organization name with some date, special character, etc. Therefore, it is simpler and easier to test some combinations before launching more complex and time-consuming checks. For example, cracking a Wi-Fi password with a wordlist can take several hours and can fail, even if you choose a great wordlist because there was no such password in it like Evilcorp2019.

Therefore, using the generated wordlist, it is possible to organize a targeted and effective online password check.

The hashcat rule syntax is used to generate the wordlist. By default, the generator uses a set of rules “online.rule”, which performs the following mutations:

  1. Adding special characters and popular endings to the end of the word – !,!@, !@#, 123! etc. evilcorp!, evilcorp!123
  2. Adding digits from 1 to 31, from 01 to 12 – evilcorp01, evilcorp12.
  3. Adding the date 2018-2023 – evilcorp2018, evilcorp2019
  4. Various combinations of 1-3 – evilcorp2018!
  5. Capitalize the first letter and lower the rest, apply 1-4. Evilcorp!2021

As a result, for the word evilcorp, the following passwords will be generated (216 in total):

  • evilcorp
  • Evilcorp
  • evilcorp123456
  • evilcorp2018
  • Evilcorp!2021
  • Evilcorp!2022
  • Evilcorp2018!@#

You can use your own hashcat rules, just click “Show rules” and put in the “Rules” textarea them with the list of rules you like best. Rules that are supported (source https://hashcat.net/wiki/doku.php?id=rule_based_attack):
