WhatWeb Web Scanner

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. Screenshots on the homepage.

Identify content management systems (CMS), blogging platforms, stats/analytics packages, javascript libraries, servers and more. When you visit a website in your browser the transaction includes many unseen hints about how the webserver is set up and what software is delivering the webpage. Some of these hints are obvious, eg. “Powered by XYZ” and others are more subtle. WhatWeb recognises these hints and reports what it finds.

WhatWeb has over 160 plugins and needs community support to develop more. Plugins can identify systems with obvious signs removed by looking for subtle clues. For example, a WordPress site might remove the tag but the WordPress plugin also looks for “wp-content” which is less easy to disguise. Plugins are flexible and can return any datatype, for example plugins can return version numbers, email addresses, account ID’s and more.

There are both passive and aggressive plugins, passive plugins use information on the page, in cookies and in the URL to identify the system. A passive request is as light weight as a simple GET / HTTP/1.1 request. Aggressive plugins guess URLs and request more files. Plugins are easy to write, you don’t need to know ruby to make them.
