1. About WhatWeb
================================================================================

WhatWeb identifies websites. Its goal is to answer the question, "What is that Website?". WhatWeb recognises web technologies including content management systems (CMS), blogging platforms, statistic/analytics packages, JavaScript libraries, web servers, and embedded devices. WhatWeb has over 1500 plugins, each to recognise something different. WhatWeb also identifies version numbers, email addresses, account IDs, web framework modules, SQL errors, and more.

WhatWeb can be stealthy and fast, or thorough but slow. WhatWeb supports an aggression level to control the trade off between speed and reliability. When you visit a website in your browser, the transaction includes many hints of what web technologies are powering that website. Sometimes a single webpage visit contains enough information to identify a website but when it does not, WhatWeb can interrogate the website further. The default level of aggression, called 'stealthy', is the fastest and requires only one HTTP request of a website. This is suitable for scanning public websites. More aggressive modes were developed for in penetration tests.

Most WhatWeb plugins are thorough and recognise a range of cues from subtle to obvious. For example, most WordPress websites can be identified by the meta HTML tag, e.g. '<meta name="generator" content="WordPress 2.6.5">', but a minority of WordPress websites remove this identifying tag but this does not thwart WhatWeb. The WordPress WhatWeb plugin has over 15 tests, which include checking the favicon, default installation files, login pages, and checking for "/wp-content/" within relative links.


Features:
	* Over 1500 plugins
	* Control the trade off between speed/stealth and reliability
	* Plugins include example URLs
	* Performance tuning. Control how many websites to scan concurrently.
	* Multiple log formats: Brief (greppable), Verbose (human readable), XML, JSON, MagicTree, RubyObject, MongoDB.
	* Proxy support including TOR
	* Custom HTTP headers
	* Basic HTTP authentication
	* Control over webpage redirection
	* Nmap-style IP ranges
	* Fuzzy matching
	* Result certainty awareness
	* Custom plugins defined on the command line

        Description:

--------------------------------------------------------------------------------
1 plugins found


All plugins are loaded by default.

Plugins can be selected by directories, files or plugin names as a comma delimited list with the -p or --plugin command line option.

Each list item may have a modifier: + adds to the full set, - removes from the full set and no modifier overrides the defaults.

Examples :

	--plugins +plugins-disabled,-foobar
	--plugins +/tmp/moo.rb
	--plugins foobar (only select foobar)
	-p title,md5,+./plugins-disabled/
	-p ./plugins-disabled,-md5


The --dorks <plugin name> command line option returns google dorks for the selected plugin.

For example, --dorks wordpress returns "is proudly powered by WordPress"

The --grep, -g command line option searches the target page for the selected string and returns a match in a plugin called Grep if it is found.


6. Aggression
================================================================================

WhatWeb features several levels of aggression. By default the aggression level is set to 1 (stealthy) which sends a single HTTP GET request and also follows redirects.

--aggression, -a

	1. Stealthy	Makes one HTTP request per target. Also follows redirects.
  	2. Unused
  	3. Aggressive	Can make a handful of HTTP requests per target. This triggers
	  		aggressive plugins for targets only when those plugins are
	  		identified with a level 1 request first.
	4. Heavy	Makes a lot of HTTP requests per target. Aggressive tests from
  			all plugins are used for all URLs.

Level 3 aggressive plugins will guess more URLs and perform actions that are potentially unsuitable without permission. WhatWeb currently does not support any intrusion/exploit level tests in plugins.

An example of the different results between level 1 and level 3:
-----------------------------------------------------------------
A level 1, stealthy scan identifes that smartor.is-root.com/forum/ uses phpBB version 2:

$ ./whatweb smartor.is-root.com/forum/
http://smartor.is-root.com/forum/ [200] PasswordField[password], HTTPServer[Apache/2.2.15], PoweredBy[phpBB], Apache[2.2.15], IP[88.198.177.36], phpBB[2], PHP[5.2.13], X-Powered-By[PHP/5.2.13], Cookies[phpbb2mysql_data,phpbb2mysql_sid], Title[Smartors Mods Forums - Reloaded], Country[GERMANY][DE]

A level 3, aggressive scan triggers additional tests in the phpBB plugin which identifies that the website uses phpBB version 2.0.20 or higher:

$ ./whatweb -p plugins/phpbb.rb -a 3 smartor.is-root.com/forum/
http://smartor.is-root.com/forum/ [200] phpBB[2,>2.0.20]

Note the use of the -p argument to select only the phpBB plugin. It is advisable, but not mandatory, to select a specific plugin when attempting to fingerprint software versions in aggressive mode. This approach is far more stealthy as it will limit the number of requests.

WhatWeb has no caching so if you use aggressive plugins on redirecting URLs you may fetch the same files multiple times.


7. Performance & Stability
================================================================================

WhatWeb features several options to increase performance and stability.

  --max-threads, -t     Number of simultaneous threads. Default: 25.
  --open-timeout        Time in seconds. Default: 15
  --read-timeout        Time in seconds. Default: 30
  --wait=SECONDS        Wait SECONDS between connections
                        This is useful when using a single thread.

The --wait and --max-threads commands can be used to assist in IDS evasion.

Changing the user-agent using the -U or --user-agent command line option will avoid the Snort IDS rule for WhatWeb.

If you are scanning ranges of IP addresses, it is much more efficient to use a port scanner like nmap to discover which have port 80 open before scanning with WhatWeb.

Character set detection, with the Charset plugin dramatically decreases performance by requiring more CPU. This is required by JSON and MongoDB logging.



8. Optional Dependencies
================================================================================

To enable JSON logging install the json gem.
	gem install json

To enable MongoDB logging install the mongo gem.
	gem install mongo

To enable character set detection and MongoDB logging install the rchardet gem.
	gem install rchardet
