WhatWeb just updated to v0.4.2

WhatWeb is a next generation web scanner that identifies what websites are running. Flexible plugin architecture with over 80 plugins so far. Passive plugins use information in the headers, cookies, HTML body and URL. Aggressive plugins can identify versions of Joomla, phpBB, etc by making extra requests to the webserver

Version 0.4.2

  • Added header-hash plugin. Makes a hash of the first 500 characters. This is useful to identify unknown systems
  • Added footer-hash plugin. Makes a hash of the last 500 characters, only if the page has > 1000 characters. This is useful to identify unknown systems
  • Added div-span-structure plugin. Makes a hash of a signature of div and span tags. This is useful to identify unknown systems
  • Added MikroTik Router plugin. Recognises version
  • Fixed a bug where the URL had a ? suffix. This caused some types of http servers to repspond incorrectly.
  • Added SquirrelMail plugin. Recognises version
  • Added SearchFitShoppingCart plugin. Recognises version
  • Added RoundCube plugin.
  • Modified OSCommerce plugin. Recognises security warnings about file permissions and installation directory.
  • Changed output colour to be more readable. Plugins that create hashes are in grey
  • Changed output order of plugins, so plugins that create hashes come last

WhatWeb has over 80 plugins and needs community support to develop more. Plugins can identify systems with obvious signs removed by looking for subtle clues.

There are both passive and aggressive plugins, passive plugins use information on the page, in cookies and in the URL to identify the system. Aggressive plugins guess URLs and request more files. Plugins are easy to write, you don’t need to know ruby to make them.
