How to do phishing With XSS Vulnerability | Advance Level of Phishing



Before i start my Article first i would like to tell if your a newbie or you r new to hacking then you can learn phishing here in my previous articles:
                                
facebook phishing  , How to perform phishing manually


Advantages over normal phishing:
In Normal phishing the victim will be given a link which is made by the hacker. A person with basic knowledge can recognize that it was a fake link.But in XSS the victim cannot suspect the link because it contains a trusted URL.



Now lets start , in this article i will be showing you that how you will craft your link into A Clint side script link of a XSS vulnerable website. which will confuse even a Smart victim to click on the link & enter private data like emails,password because the phisher link wiill be crafted in the original link of Xss vulnerable website.
                                 
What is Cross site Scripting(XSS)?
It is a vulnerability typically found in web applications.A hacker can use this vulnerability to inject client-side script into web pages viewed by other users. 


  • A Web application vulnerable to XSS allows a user to inadvertently send malicious data to self through that application.


  • Attackers often perform XSS exploitation by crafting malicious URLs and tricking users into clicking on them.


  • These links cause client side scripting languages )VBScript, JavaScript etc,) of the attacker s choice to execute on the victim's browser.


  • XSS vulnerabilities are caused by a failure in the web application to properly validate user input.
  • What can an attacker do with this?

    •  Steal user cookies and can take complete account takeover
    •  Steal data on web pages viewed by victim
    •  Deface pages viewed by victim
    •  Use web pages for phishing


    Lets Start Our Attack Demonstration:



    1. The very firs thing you have to do is, find An Xss Vulnerable Website


    This can be done using google. Go to google and search using the following Dork.
    inurl: "search.php?q="
    To test the vulnerability you can inject the following code in search fields,comment fields of your website.
    <script>alert("hacker dev")</script>
    If it returns an alert box showing “hacker dev”, That site is vulnerable to XSS.


    2. this is a very main part , how to craft your link:
    Your link will look like
    http://site.com/search.php?q=<script>alert("you are hacked")</script>
    You can use your specially crafted link to steal your victim’s information just as in phishing|

     EXAMPLE:
    I am showing you an example with vulnerable link found in google.
    Note:
    This link is kept here for demonstration purpose only. I will not be held responsible if you do any thing illegal with this and this bug is not fixed yet. If google fixes it,it may not work.


    http://www.google.com/search?btnI&q=allinurl:http://www.devzcyberarena.blogspot.com/
    You can replace “http://www.devzcyberarena.blogspot.com/” with your fake login page’s link.Then it takes the victim to your fake login page.

    Step 3:Send the link to your victim
    Now you can send your specially crafted link to the victim by any means as you do in normal phishing.


    This is such a dangerous vulnerability in web applications. It got 2nd rank in OWASP top 10 vulnerabilities.If a hacker finds this vulnerability in any of the bank websites, he can attempt a malicious attack against the customers of the bank and steal lots of information like credit cards, account numbers, passwords etc by simply sending a group mail to the customers of the bank.
