WHATWEB(1)WHATWEB(1)NAME
WhatWeb - Web scanner to identify what websites are running.
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 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 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:
* Over 1000 plugins
* Control the trade off between speed/stealth and reliability
* Performance tuning. Control how many websites to scan concur‐
rently.
* Multiple log formats: Brief (greppable), Verbose (human read‐
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
* 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 (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 -

title,md5,+./plugins-disabled/
./plugins-disabled,-md5
--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=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-sql=FILE
Log SQL INSERT statements
--log-sql-create=FILE
Create SQL database tables
--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
--no-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.
--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

by abc'" ":regexp=>/powered[ ]?by ab[0-9]/" ":ghdb=>'intitle:abc
"powered by abc"'" ":md5=>'8666257030b94d3bdb46e05945f60b42'"
