Method 1. Find a vulnerable site where you can post content. A message board is a good example. Remember, if the site is not vulnerable to a cross-site scripting attack, then this will not work.
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. 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 and is vulnerable to remote code execution via upload. An example cookie catcher code can be found in the sample section.
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. Use the collected cookies. After this, you can use the cookie information, which should be saved to your website, for whatever purpose you need. Method 2. Find a vulnerable site. You will need to find a site that is vulnerable, due to an easily accessible admin login.
Try searching on your favorite search engine for admin login. Login as an admin. Type admin as the username and use one of a number of different strings as the password. Be patient. This is probably going to require a little trial and error. 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.
Then, logged in as an administrator, you can perform further actions, such as uploading a web shell to gain server-side access if you can perform a file upload. Method 3. 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, PHP necessary for exploiting server-side vulnerabilities or SQL, so that you can gain better control of computers and identify vulnerabilities in systems.
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. 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. This returns the results shown in the screengrab above. Having a huge number of sites which may or may not be vulnerable is not much use unless you can pinpoint one which is actually open to attack. This is when a programme called a vulnerability scanner comes into its own and the most popular is called Acunetix. Acunetix, developed by a UK-based company, was designed, and is still used, as a tool for web developers to test sites they are building.
However the hacking community has commandeered the tool and uses it to identify existing vulnerable sites. You can download a trial version of the software for free from the official Acunetix website or if you venture into the murky depths of a hacker forum and search for Acunetix, you can find cracked versions of the full application freely available. Acunetix, as you can see from the screen shots above, is a simple, straight-forward Windows application and all you need to do is enter the URL of the site you want to target, and press Process.
Acunetix will scan the entire website, including all pages associated with it, and return a list of vulnerabilities it finds. If you find the type you are looking for, you will need to move onto Step 3, as Acunetix does not perform any website penetration.
Attacking a website is done by two main methods. The first is by carrying out a Distributed Denial of Service DDoS attack which overwhelms a website's servers and forces it to shut down.
We will deal with this type of attack later, but first we will look at how you can hack into an account and steal some information contained within databases on the site. This type of attack is known as a SQL pronounced sequel Injection. SQL is a programming language designed for managing data in a database.
The following are common web application threats. In this website hacking practical scenario, we are going to hijack the user session of the web application located at www. We will use cross site scripting to read the cookie session id then use it to impersonate a legitimate user session.
The assumption made is that the attacker has access to the web application and he would like to hijack the sessions of other users that use the same application. The above code uses JavaScript. It adds a hyperlink with an onclick event. Note : the value you get may be different from the one in this webpage hacking tutorial, but the concept is the same.
