WHATWEB(1)WHATWEB(1)NAME
WhatWeb - Next generation Web scanner. Identify technologies used by
websites.
SYNOPSISwhatweb [options] <URLs>
DESCRIPTION
WhatWeb identifies websites. It's goal is to answer the question, "What
is that Website?". WhatWeb recognises web technologies including con‐
tent management systems (CMS), blogging platforms, statistic/analytics
packages, JavaScript libraries, web servers, and embedded devices.
WhatWeb has over 1700 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 sup‐
ports 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 iden‐
tify a website but when it does not, WhatWeb can interrogate the web‐
site further. The default level of aggression, called 'passive', is the
fastest and requires only one HTTP request of a website. This is suit‐
able 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 identi‐
fied by the meta HTML tag, e.g. '<meta name="generator" content="Word‐
Press 2.6.5">', but a minority of WordPress websites remove this iden‐
tifying 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:

able), XML, JSON, MagicTree, RubyObject, MongoDB, SQL.
* Proxy support including TOR
* Custom HTTP headers
* Basic HTTP authentication
* Control over webpage redirection
* Nmap-style IP ranges

TARGET SELECTION
<URLs> Enter URLs, filenames or nmap-format IP ranges. Use /dev/stdin
to pipe HTML directly
--input-file=FILE -i

Add a prefix to target URLs
--url-suffix
Add a suffix to target URLs
--url-pattern

AGGRESSION
The aggression level controls the trade-off between speed/stealth and
reliability.
--aggression -a=LEVEL
Set the aggression level. Default: 1.
1. Stealthy Makes one HTTP request per target and also follows
redirects.
3. Aggressive If a level 1 plugin is matched, additional requests
will be made.
4. Heavy Makes a lot of HTTP requests per target. URLs from
all plugins are attempted.
HTTP OPTIONS--user-agent, -U=AGENT
Identify as AGENT instead of WhatWeb/0.4.9.
--header, -H
Add an HTTP header. eg "Foo:Bar". Specifying a default header
will replace it. Specifying an empty value, e.g. "User-Agent:"
will remove it.
--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 redirects. Default: 10.
AUTHENTICATION--user, -u=<user:password>

title,md5,+./plugins-disabled/
-p + is a shortcut for -p +plugins-disabled.
--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'"
