DOM Based Cross Site Scripting(XSS) vulnerability Tutorial

So far i have explained about the Traditional Cross site scripting that occurs because of insecure server-side code. In this post , i am going to explain the DOM Based Cross Site Scripting vulnerability. if you don't what cross site scripting is, then i recommend you to read the basics from here.
Before explaining about the DOM based xss, let me explain what DOM is.
DOM is expanded as Document object model that allows client-side-scripts(Eg: Javascript) to dynamically access and modify the content, structure, and style of a webpage.
Like server-side scripts, client-side scripts can also accept and manipulate user input with the help of DOM.

Here is a very simple HTML code that accepts and writes user input using JavaScript with the help of DOM.

How to make your application run when windows loads

Ok this one isn't to hard, you just need to learn how to use the registry API functions... I'm not going to go over what the windows registry is, if you don't know i advise you google it Wink.

In the registry there is a (path)key that windows reads, in that key is a list of sub-keys, there values contain file paths which are executed when windows loads, so in order to make our server load on startup we just need to add a sub-key into this key containing the path to our server, make sense Wink.

Break Into Email Accounts, Email hacking



Introduction



I have written this tutorial to address a question that is all too commonly asked in any channel/chat room with "hack" in the title (asked in frequency to the point of harrassment really). So since this is a question that so many people ask, then I believe that there should at least be an answer available (regardless of the morality or "lameness" of such a question). So you as the reader are most likely reading this because you want to break into somebody's email account.


Well, you must understand that there is no 1-2-3 process to anything. I will give you options to consider when persuing such a task, but it will ultimately be up to you to do this. This is what you want to do, and no matter what sort of offers you throw up at anybody, nobody is going to do this for you. There is no program that is going to do all this for you. Also don't forget that nobody is going to hold your hand and lead you through this. I'm offering you as the reader suggestions for ways you can address this task, and that is about all the help you are going to get from anybody. So now that I've made all that clear, let's begin...

Breaking CAPTCHA without OCR

For my own PHP CAPTCHA implementation, click here.
This article details a method I have discovered to bypass CAPTCHA security, without having to use Optical Character Recognition software. It depends on an implementation problem that was quite common among CAPTCHA scripts when I originally published this in May 2005.
Most CAPTCHAs don’t destroy the session when the correct phrase is entered. So by reusing the session id of a known CAPTCHA image, it is possible to automate requests to a CAPTCHA-protected page.
I have tested a number of free and commercial CAPTCHA scripts, and most of them are vulnerable to this method of exploitation. This includes the popular humanVerify solution, and many others.
