Subject: New Tool: Username Anarchy

Hi FD,

Have you ever discovered a user's real name on a pentest and then had to make a list of potential
usernames so you could bruteforce some passwords, Apache home directories, etc? It sucked didn't
it..? With username-anarchy you can generate usernames without tears.

Feedback is welcome.




Username Anarchy
======================================

* Version: 0.2 (November 2012)
* Author: urbanadventurer (Andrew Horton)
* Homepage: http://www.morningstarsecurity.com/research/username-anarchy
* Download: https://github.com/urbanadventurer/username-anarchy/archive/master.zip

Description
------------
Tools for generating usernames when penetration testing. *Usernames are half the password brute
force problem.*

This is useful for user account/password brute force guessing and username enumeration when
usernames are based on the users' names. By attempting a few weak passwords across a large set of
user accounts, user account lockout thresholds can be avoided.

Users' names can be identified through a variety of methods:
* Web scraping employee names from LinkedIn, Facebook, and other social networks.
* Extracting metadata from document types such as PDF, Word, Excel, etc. This can be performed with
FOCA.

Common aliases, or self chosen usernames, from forums are also included.


Features
--------

* Plugin architecture for username formats
* Format string style username format definitions
* Substitutions. e.g. when only a first initial and lastname is known (LinkedIn lists users like
this), it will attempt all possible first names
* Country databases of common first and last names from Familypedia and PublicProfiler
* Has the Facebook common first and lastnames lists


Extras
------

* Common forum usernames, ordered by popularity
