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
Usage
Username Anarchy is a command line tool.
