Overview & Goal
WebSlayer is a tool designed for bruteforcing Web Applications, it can be used for finding not linked resources (directories, servlets, scripts, etc), bruteforce GET and POST parameters, bruteforce Forms parameters (User/Password), Fuzzing, etc.

The tools have a payload generator and a easy and powerful results analyzer.


Some features are:

  • Encodings: 15 encodings supported
  • All parameters attack: the tool will inject the payload in every parameter (Headers, Get, Post)
  • Authentication: Webslayer supports Ntml and Basic authentication, also you can brute force the authentication
  • Multiple payloads: you can use 2 paylods in different parts
  • Proxy support (authentication supported)
  • Live filters: You can change the filters as the attack is taking place
  • Multiple threads: You can set how many threads to use in the attack
  • Session import/export: Allows you to save the session and to continue working with the results
  • Integrated web browser: a full fledge webkit browser is included to analyze the results
  • Predefined dictionaries for predictable resource location, based on known servers (Thanks to Dark Raver,
  • Payload Generator (custom payload generator)
Contents Materials
The training will show how to use the tool and will cover the following topics:
  • Interface overview
  • Basic Payloads overview
  • Basic directory discovery setup
  • Advance directory and file discovery
  • Login form brute force attack
  • Basic authentication attack
  • Custom payload generation
  • Advanced uses


The training is a hands on course, so it is recommended to bring your own laptop (it´s possible to follow the training without a computer)

The latest version of Webslayer can be downloaded from google code subversion here.
