About WhoKnows

WhoKnows is a Penetration test tool and webscanner that can penetrate websites, domains, sub domainss, DNS, metadata, web crawling, web scraping, IPs, web technologies including content management systems (CMS), blogging platforms, statistic/analytics packages, JavaScript libraries, web servers, and embedded devices. WhoKnows has over 1800 plugins by diffrent authors around the globe, each to recognise something different. WhoKnows also identifies version numbers, email addresses, account IDs, web framework modules, SQL errors, and more.

WhoKnows is flexible can be stealthy and fast, or thorough but slow. WhoKnows 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, WhoKnows 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 WhoKnows 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 WhoKnows. The WordPress WhoKnows plugin has over 15 tests, which include checking the favicon, default installation files, login pages, and checking for “/wp-content/” within relative links.

Logging & Output

The following types of logging are supported:

You can output to multiple logs simultaneously by specifying multiple command line logging options. Advanced users who want SQL output should read the source code to see unsupported features.

Description:    phpBB is a free forum 
Website:        http://phpbb.org/

Google Dorks:

================================================================================

Plugin Selection

All plugins are loaded by default.

Plugins can be selected by directories, files or plugin names as a comma delimited list with the -p or –plugin command line option.

Each list item may have a modifier: + adds to the full set, - removes from the full set and no modifier overrides the defaults.

Examples

The –dorks command line option returns google dorks for the selected plugin. For example, --dorks wordpress returns "is proudly powered by WordPress"

The –grep, -g command line option searches the target page for the selected string and returns a match in a plugin called Grep if it is found.

Aggression

WhoKnows features several levels of aggression. By default the aggression level is set to 1 (stealthy) which sends a single HTTP GET request and also follows redirects.

--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.

Level 3 aggressive plugins will guess more URLs and perform actions that are potentially unsuitable without permission. WhoKnows currently does not support any intrusion/exploit level tests in plugins.

An example of the different results between level 1 and level 3:

A level 1, stealthy scan identifies that smartor.is-root.com/forum/ uses phpBB version 2:

$ ./whoknows smartor.is-root.com/forum/
http://smartor.is-root.com/forum/ [200] PasswordField[password], HTTPServer[Apache/2.2.15], PoweredBy[phpBB], Apache[2.2.15], IP[88.198.177.36], phpBB[2], PHP[5.2.13], X-Powered-By[PHP/5.2.13], Cookies[phpbb2mysql_data,phpbb2mysql_sid], Title[Smartors Mods Forums - Reloaded], Country[GERMANY][DE]

A level 3, aggressive scan triggers additional tests in the phpBB plugin which identifies that the website uses phpBB version 2.0.20 or higher:

$ ./whoknows -p plugins/phpbb.rb -a 3 smartor.is-root.com/forum/
http://smartor.is-root.com/forum/ [200] phpBB[2,>2.0.20]

Note the use of the -p argument to select only the phpBB plugin. It is advisable, but not mandatory, to select a specific plugin when attempting to fingerprint software versions in aggressive mode. This approach is far more stealthy as it will limit the number of requests.

WhoKnows has no caching so if you use aggressive plugins on redirecting URLs you may fetch the same files multiple times.

Plugins

Please refer to the Plugins Wiki for full tutorial on plugin development.

WhoKnows lets you identify content management systems (CMS), blogging platforms, stats/analytics packages, javascript libraries, servers and more. When you visit a website in your browser the transaction includes many unseen hints about how the webserver is set up and what software is delivering the webpage. Some of these hints are obvious, eg. “Powered by XYZ” and others are more subtle. WhoKnows recognises these hints and reports what it finds.

WhoKnows has many plugins and needs community support to develop more. Plugins can identify systems with obvious identifying hints removed by also looking for subtle clues. For example, a WordPress site might remove the tag but the WordPress plugin also looks for “wp-content” which is less easy to disguise. Plugins are flexible and can return any datatype, for example plugins can return version numbers, email addresses, account ID’s and more.

Performance & Stability

WhoKnows features several options to increase performance and stability.

The –wait and –max-threads commands can be used to assist in IDS evasion.

Changing the user-agent using the -U or –user-agent command line option will avoid the Snort IDS rule for WhoKnows.

If you are scanning ranges of IP addresses, it is much more efficient to use a port scanner like massscan to discover which have port 80 open before scanning with WhoKnows.

Character set detection, with the Charset plugin dramatically decreases performance by requiring more CPU. This is required by JSON and MongoDB logging.

Optional Dependencies

To enable MongoDB logging install the mongo gem. gem install mongo

To enable character set detection and MongoDB logging install the rchardet gem. gem install rchardet cp plugins-disabled/charset.rb my-plugins/

Writing Plugins

Plugins are easy to write. Start by going through the plugin tutorials in the my-plugins/ folder.

An overview of the plugin tutorials is here. plugin-tutorials.txt

After progressing through the tutorials read through the Development section of the wiki.
