+### TL;DR;
+
+Chatur is a Javascript based port scanner. This tool proves the vulnerability of
+fingerprinting open TCP ports at client workstation using Javascript.
+
+
+### Background
+
+Recently, I came across a possibility to fingerprint open TCP ports at client
+workstation using browser side (aka client side) Javascript. This attack is
+discovered by AndLabs in the year 2010. In this section, I will explain the
+anatomy of this venerability in the simplest way. Knowledge of basic XML HTTP
+Request is expected to understand this post.
+
+
+#### What happens when you fire an XHR?
+
+Browser initiates a TCP socket at the destination URL and sends header and body
+of the request. Once header and body is sent, browser terminates the active
+socket and waits for the server to deliver a response. That is how HTTP works
+under the hood.
+
+
+#### How to fingerprint open TCP port of client workstation?
+
+
+If I write a Javascript code to put a XHR to 'http://localhost:8084' and host
+that code at 'xyz.com' then when you visit the 'xyz.com' the browser will fire
+that XHR to port '8084' of your workstation because 'localhost' for your browser
+is your workstation. This gap invites many vulnerabilities for user.  One of
+them is the possibility to fingerprint open TCP ports at client workstation.
+
+While counting the time browser took to receive headers from the destination
+were highlighting a clear pattern. A XHR to port where no service was running
+were returning quick than a occupied port.
+
+
+#### Algorithm
+
+1. Fire a bunch of XHR at a target port of client workstation.
+2. Measure the time browser took to receive the response headers
+3. If timing of response headers is greater than the usual response time
+   repetitively consider that any service is running on that port.
+
+
+You should read
+[this](http://blog.andlabs.org/2010/12/port-scanning-with-html5-and-js-recon.html)
+blog post published by the AndLabs which is briefly describing this
+venerability.
+
+### Chatur
+
+#### How to pronounce Chatur?
+
+The Cha is Charming and Tur is Turn. Cha-Tur. You can observe
+[this][chatur_videp]
+
+#### How Chatur works?
+
+Chatur accepts range of ports and floods all them with XHR. It captures the
+response time browser took to return the headers for all the requests. From
+header response time of all the requests, unusual hike is considered as occupied
+port.
+
+#### My motivation for writing this tool
+
+Browser is the most common tool used by us. Asserting this venerability requires
+knowledge of Javascript and everyone is not a developer. Despite trying hard, I
+failed to find the source code of JS-Recon (the tool written by AndLabs proving
+possibility of this attack). I am sharing this tool so that you or anyone else
+irrespective of your technical backgrounds can try this tool to verify the
+possibility of this attack.
