WhatWeb - Next generation web scanner

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. '', 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.

Usage: whatweb [options] 

TARGET SELECTION:
    Enter URLs, filenames or nmap-format IP ranges.
   Use /dev/stdin to pipe HTML directly
  --input-file=FILE, -i Identify URLs found in FILE, eg. -i /dev/stdin

TARGET MODIFICATION:
  --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 

AGGRESSION:
  The aggression level controls the trade-off between speed/stealth and
  reliability.
  --aggression, -a=LEVEL Set the aggression level. Default: 1
  Aggression levels are:
  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.

HTTP OPTIONS:
  --user-agent, -U=AGENT Identify as AGENT instead of WhatWeb/0.4.8-dev.
  --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.
  --follow-redirect=WHEN Control when to follow redirects. WHEN may be `never',
   `http-only', `meta-only', `same-site', `same-domain'
   or `always'. Default: always
  --max-redirects=NUM Maximum number of contiguous redirects. Default: 10

AUTHENTICATION:
  --user, -u= HTTP basic authentication
  Add session cookies with --header, e.g. --header "Cookie: SESSID=1a2b3c;"

PROXY:
  --proxy   Set proxy hostname and port Default: 8080
  --proxy-user   Set proxy user and password

PLUGINS:
  --list-plugins, -l List all plugins
  --plugins, -p=LIST Select plugins. LIST is a 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
   -p + is a shortcut for -p +plugins-disabled
  --info-plugins, -I=PLUGINS Display detailed information for plugins. 
Optionally search with keywords in a comma delimited list.
  --grep, -g=STRING Search for STRING in HTTP responses. Reports with a plugin named Grep
  --custom-plugin=DEFINITION Define a custom plugin named Custom-Plugin,
   Examples: ":text=>'powered by abc'"
   ":version=>/powered[ ]?by ab[0-9]/"
   ":ghdb=>'intitle:abc \"powered by abc\"'"
   ":md5=>'8666257030b94d3bdb46e05945f60b42'"
   "{:text=>'powered by abc'},{:regexp=>/abc [ ]?1/i}"
  --dorks=PLUGIN List google dorks for the selected plugin
  --example-urls, -e=PLUGIN Update the target list with example URLs from
   the selected plugins.

OUTPUT:
  --verbose, -v  Verbose output includes plugin descriptions. Use twice
   for debugging.
  --colour,--color=WHEN control whether colour is used. WHEN may be `never',
   `always', or `auto'
  --quiet, -q  Do not display brief logging to STDOUT
  --no-errors  Suppress error messages

  --log-brief=FILE Log brief, one-line output
  --log-verbose=FILE Log verbose 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 of the MongoDB database
  --log-mongo-collection Name of the MongoDB collection. Default: whatweb
  --log-mongo-host MongoDB hostname or IP address. Default: 0.0.0.0
  --log-mongo-username MongoDB username. Default: nil
  --log-mongo-password MongoDB password. Default: nil
  --log-errors=FILE Log errors

PERFORMANCE & STABILITY:
  --max-threads, -t Number of simultaneous threads. Default: 25.
  --open-timeout Time in seconds. Default: 15
