Introduction

Username Anarchy is 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

Usage

Username Anarchy is a command line tool.
