WhatWeb - Web scanner to identify what websites are running.


whatweb [options] <URLs>


WhatWeb identifies websites. It's 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 900 plugins, each to recognise something different. WhatWeb also
identifies version numbers, email addresses, account ID's, 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 'passive', 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.

MagicTree, RubyObject, MongoDB, SQL.

* Proxy support including TOR

* Custom HTTP headers

* Result certainty awareness

* Custom plugins defined on the command line


<URLs> Enter URLs, filenames or nmap-format IP ranges. Use /dev/stdin to pipe HTML

--input-file=FILE -i
Identify URLs found in FILE

--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.

--list-plugins -l
List the plugins

--plugins -p
Comma delimited set of selected plugins. Default is all.
Each element can be a directory, file or plugin name and
can optionally have a modifier, eg. + or -
Examples: +/tmp/moo.rb,+/tmp/foo.rb

--info-plugins -I
Display information for all plugins. Optionally search
with keywords in a comma delimited list.

--grep -g
Search for a string. Reports in a plugin called Grep

--colour=[WHEN] --color=[WHEN]
control whether colour is used. WHEN may be "never", "always", or "auto"

Log verbose output

--quiet, -q
Do not display brief logging to STDOUT

Log brief, one-line output

Log XML format

Log JSON format

Log SQL INSERT statements

Create SQL database tables

Log JSON Verbose format

Log MagicTree XML format

Log Ruby object inspection format

Name of the MongoDB database

Name of the MongoDB collection. Default: whatweb

MongoDB hostname or IP address. Default:

MongoDB username. Default: nil

MongoDB password. Default: nil

Log errors

Suppress error messages

--user-agent -U
Identify as user-agent instead of WhatWeb/VERSION.

--user -u <user:password>
HTTP basic authentication

--header -H
Add an HTTP header. eg "Foo:Bar". Specifying a default
header will replace it. Specifying an empty value, eg.
"User-Agent:" will remove the header.

--max-threads -t
Number of simultaneous threads. Default is 25.

Control when to follow redirects. WHEN may be "never", "http-only", "meta-only",
"same-site", "same-domain" or "always"

Maximum number of contiguous redirects. Default: 10

--proxy <hostname[:port]>
Set proxy hostname and port (default: 8080)

--proxy-user <username:password>
Set proxy user and password

Time in seconds. Default: 15

Time in seconds. Default: 30

Wait SECONDS between connections. This is useful when using a single thread.

Define a custom plugin call Custom, Examples: ":text=>'powered by abc'"
":regexp=>/powered[ ]?by ab[0-9]/" ":ghdb=>'intitle:abc "powered by abc"'"
":md5=>'8666257030b94d3bdb46e05945f60b42'" "{:text=>'powered by
abc'},{:regexp=>/abc [ ]?1/i}"

--dorks <plugin name>
List google dorks for the selected plugin

Add a prefix to target URLs

Add a suffix to target URLs

Insert the targets into a URL. Requires --input-file, eg.

--help -h
Display usage

--verbose -v
Increase verbosity (recommended), use twice for debugging.

Raise errors in plugins.

Display version information.
