WHATWEB(1)

NAME
WhatWeb - Web scanner to identify what websites are running.

SYNOPSIS
whatweb [options] <URLs>

DESCRIPTION

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.

Features:

* Over 900 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.

* Recursive web spidering

* 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

OPTIONS

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

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

--aggression -a
    1 (Passive) - Make one HTTP request per target. Except
     for redirects. 2 (Polite) - Reserved for future use 3 (Aggressive) - Triggers aggressive plugin functions only when
     a plugin matches passively. 4 (Heavy) - Trigger aggressive functions for all plugins. Guess a lot of URLs like Nikto.

--recursion -r
    Follow links recursively. Only follows links under the path (default: off)

--depth -d
    Maximum recursion depth (default: 10)

--max-links -m
    Maximum number of links to follow on one page (default: 250)

--spider-skip-extensions
    Redefine extensions to skip. (default: zip,gz,tar,jpg,exe,png,pdf)

--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
     title,md5,+./plugins-disabled/
     ./plugins-disabled,-md5

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

--example-urls -e
    Add example urls for each plugin to the target list

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

--log-verbose=FILE
    Log verbose output

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

--log-brief=FILE
    Log brief, one-line output

--log-xml=FILE
    Log XML format

--log-json=FILE
    Log JSON format

--log-json-verbose=FILE
    Log JSON Verbose format

--log-magictree=FILE
    Log MagicTree XML format

--log-object=FILE
    Log Ruby object inspection format

--log-mongo-database=NAME
    Name of the MongoDB database

--log-mongo-collection=NAME
    Name of the MongoDB collection. Default: whatweb

--log-mongo-host=NAME
    MongoDB hostname or IP address. Default: 0.0.0.0

--log-mongo-username=NAME
    MongoDB username. Default: nil

--log-mongo-password=NAME
    MongoDB password. Default: nil

--log-errors=FILE
    Log errors

--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.

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

--max-redirects=NUM
    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

--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.

--custom-plugin
    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}"

--url-prefix
    Add a prefix to target URLs

--url-suffix
    Add a suffix to target URLs

--url-pattern
    Insert the targets into a URL. Requires --input-file, eg. www.example.com/%insert%/robots.txt

--help -h
    Display usage

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

--debug
    Raise errors in plugins.

--version
    Display version information.

EXAMPLES

Passive:
     whatweb example.com

Passive (Verbose):
     whatweb -v example.com

Aggressive:
     whatweb -a 3 example.com

IP Ranges
     whatweb 192.168.1.0/24

BUGS
WhatWeb is not compatible with Ruby 1.9 Do not use aggressive plugins with recursive site crawling. Logging modes append to the user-selected log file by default.
 Appending will result in malformed XML due to multiple <xml> tags
 in XML and MagicTree logging modes.
