MediaCrack

MediaCrack is a password revorery tool for MediaWiki "B" passwords. "B" type passwords consist of the following components:

  • A colon and the capital letter "B", followed by
  • A colon and a pseudo-random eight-digit hex salt, followed by
  • A colon and the MD5 hash of a concatenation of:
    • The eight-digit hex salt,
    • A dash ("-"), and
    • The MD5 hash of the password

Requirements

  • OpenSSL library
  • POSIX threads

Usage

To compile, use make.

MediaCrack takes words from standard input and attempts them in order. You can run MediaCack alongside John the Ripper:

% john --incremental=alpha --stdout | ./mediacrack :B:838c83e1:e4ab7024509eef084cdabd03d8b2972c
Salt: 838c83e1, MD5: e4ab7024509eef084cdabd03d8b2972c
Success! The password was "password"

...or provide an actual wordlist:

% cat wordlist | ./mediacrack :B:838c83e1:e4ab7024509eef084cdabd03d8b2972c
Salt: 838c83e1, MD5: e4ab7024509eef084cdabd03d8b2972c
Success! The password was "password"
