What is WhatWeb?
WhatWeb can be stealthy and fast, or thorough but slow. WhatWeb supports an aggression level to control the tradeoff 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 use 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.
We wrote about WhatWeb way back in 2010, and there actually hasn’t been a release since 2011 (v0.4.7). I was glad to find however it still is under active development and there is work being done on what is going to become 0.4.8 at some point, it has many changes (as listed below) but hasn’t yet been released.
But due to the wonders of technology, you can grab the unreleased development version from Github now (link also below).
