WATOBO - THE Web Application Toolbox

WATOBO is a security tool for web applications. WATOBO is intended to enable security professionals to perform efficient (semi-automated) web application security audits.

Most important features:

  • WATOBO has Session Management capabilities! You can define login scripts as well as logout signatures. So you don’t have to login manually each time you get logged out.

  • WATOBO can perform vulnerability checks out of the box.

  • WATOBO supports Inline De-/Encoding, so you don’t have to copy strings to a transcoder and back again. Just do it inside the request/response window with a simple mouse click.

  • WATOBO has smart filter functions, so you can find and navigate to the most interesting parts of the application easily.

  • WATOBO is written in (FX)Ruby and enables you to easiely define your own checks

  • WATOBO is free software ( licensed under the GNU General Public License Version 2)

  • It’s by siberas ;)


Please install Ruby 1.9.2+ first before you continue.

Note: Ruby 1.8 is no longer supported!

Note: WATOBO will not run under Ruby 1.8 anymore!

Note: Please upgrade Ruby to 1.9.2+, because WATOBO will not run under Ruby 1.8!

Note: Ruby 1.8 is crap, so get rid of it!

… just want to be sure ;)
