Lab Password Cracking - echadbourne/ChadbourneSYS-140 GitHub Wiki

Summary:

  • In this lab we used a password cracking software on Kali called JohnTheRipper to try and crack a password protected file. In order to do this we made a hash file of the password protected file, and ran JohnTheRipper on it to try and crack it's password. I have used this tool before so I knew by combining capitalization, dictionary words, and a 3 digit number I could pretty easily fool it. We saw a successful password crack too, by cracking "champ" as a password using JohnTheRipper.

Useful Information:

  • zip2john labdoc.zip > hashfile.txt - creates a text file of the hash of the password protected file
  • john hashfile.txt - runs JohnTheRipper on the hash file to see if it can crack it
