Arachni Web scanner (CLI & WEB GUI)

Download the CDE package from:

Linux users enjoy the privilege of a CDE package which is a compressed archive and contains a full preconfigured Linux environment in the form of a sandbox.

Quick Basic Usage  of Arachni:

To see help type :

$ arachni -h

You can check the options here.

You can simply run Arachni like:

$ arachni
which will load all modules, the plugins under
and audit all forms, links and cookies.

In the following example all modules will be run against, auditing links/forms/cookies and following subdomains —with verbose output enabled.

The results of the audit will be saved in the the file

$ arachni -fv
 You can do module loading by following commands using wildcard.:

To load all xss modules using a wildcard:

$ arachni --mods=xss_*

To load all audit modules using a wildcard:
$ arachni --mods=audit*

To exclude only the csrf module:
$ arachni --mods=*,-csrf

Or you can mix and match; to run everything but the xss modules:
$ arachni --mods=*,-xss_*

Performing a full scan quickly

The full profile adds header auditing to the defaults.

 You can use it like:
$ arachni --load-profile=profiles/full.afp
You have lots of options/flags/modes to explore here 
based on ur usage. 

for example we have Debug mode :

When this flag is enabled the system will output a lot of messages detailing what’s happening internally.
If you don’t want to be flooded by annoying and obscure messages you can pipe debugging output to a separate file when running Arachni using:

$ arachni -pv --mods=xss http://localhost/~zapotek/tests/forms/xss.php --debug
The debug.log file will contain something like:


Arachni WEB UI

now unzip it ,goto the folder location you will find the arachni console and web UI

There are two ways to start WEB UI :

just type in shell prompt :
$ arachni_web_autostart

This will setup a local Dispatcher, the WebUI server and even open up your browser.


Start a Dispatcher like:
$ arachni_rpcd 
Then start the WebUI by running:
$ arachni_web
And finally open up a browser window and visit: http://localhost:4567/ 

The WebUI supports HTTP Basic auth which you can configure using the Username and Password 
The WebUI can serve many purposes ranging from just a simple way to use Arachni to a Grid construction and management interface.
You can use it to perform and monitor a single scan, hassle-free, via any web-browser enabled device or use it to setup a worldwide High Performance Grid of Arachni scanners ready to combine their resources in order to perform lightning fast audits.
The first page, so eloquently entitled ‘Start a scan’, allows you to do just that.

A single scan can be performed easily enough, you just select a Dispatcher, enter the URL of your target and hit ‘Launch Scan’.

A high performance scan utilizes more than one Arachni Instance to perform the audit.

The master instance will perform the crawl and then calculate and distribute the workload amongst its slaves.
This allows scan-time to be severely decreased.

Once you have set up a Grid (i.e. configured at least 2 Dispatchers to have each other as neighbours) the “Start a scan” screen will change to this:

Modules and Plug-ins

The Modules and Plug-ins pages are pretty self-explanatory, they simply allow you to select which components to load.


Nothing special, these options have the same effects as their CLI(Command Line Interface) counterparts.


This page contains a list of audit reports along with the option to convert them to a fair amount of different formats.


Not much to add to this, the name says it all:


You can kill the WebUI by sending Ctrl+C to the console from which you started it.
